Natural Hair care Chapter 6-Practice Test

Assisting clients in understanding their hair can indeed help them improve their self-care. When clients have a better understanding of their hair type, texture, and specific needs, they can make more informed decisions about the products and treatments they use. This knowledge can lead to better hair care practices, resulting in healthier and more manageable hair. Ultimately, improved self-care in regards to hair can boost clients' confidence and overall well-being.

Chemical relaxers are used to straighten curly or kinky hair by breaking down the protein structure of the hair. This process weakens the hair strands, making them more susceptible to breakage. Hair breakage is a common side effect of using chemical relaxers because the hair becomes fragile and prone to splitting or snapping. This can result in noticeable hair loss and a decrease in overall hair volume. It is important to take proper care of relaxed hair to minimize breakage and maintain its health.

Essential oils such as peppermint, rosehip seed, lavender, and tea tree oil have healing and nurturing properties that can benefit the body. Natural hair stylists can use these essential oils to promote hair growth, improve scalp health, and provide aromatherapy benefits. They are often used in hair care products and treatments due to their natural properties and pleasant scents.

Slow therapeutic scalp and head massages are recommended to increase blood circulation and create a nurturing environment which helps relax the client. Massaging the scalp stimulates the blood vessels, promoting better blood flow to the hair follicles. Improved blood circulation brings more oxygen and nutrients to the hair follicles, which can promote hair growth. Additionally, the gentle and soothing nature of the massage can induce a sense of calmness and relaxation in the client, further enhancing the overall therapeutic experience.

During the shedding phase of the hair growth cycle, it is normal for people to lose a certain amount of hair each day. The correct answer is 50-100 hairs. This range indicates the typical amount of hair loss during this phase. It is important to note that hair loss within this range is considered normal and does not necessarily indicate a problem with hair health.

The parietal front refers to the widest area of the head, starting at the temples and ending at the bottom of the crown. This area is often associated with hair loss and thinning, which is known as diffuse alopecia or miniaturization.

When hair loss occurs, the client's self-image is impaired. Hair loss can have a significant impact on how a person perceives themselves and their overall self-esteem. It can lead to feelings of insecurity, embarrassment, and a negative body image. Hair is often seen as an important part of one's physical appearance and losing it can cause a loss of confidence. This impairment in self-image can affect various aspects of a person's life, including their social interactions and overall mental well-being.

Petroleum is the most frequently used emollient to base the scalp and hairline before applying a sodium hydroxide or lye relaxer. This is because petroleum acts as a protective barrier, preventing the relaxer from coming into direct contact with the scalp and hairline, which can cause irritation and damage. It also helps to minimize the potential for chemical burns and scalp irritation during the relaxing process. Tea tree oil and mineral oil are not commonly used as emollients in this context.

A dermatologist is a medical professional who specializes in the diseases and disorders of the skin, hair, and nails. They have extensive knowledge and training in diagnosing and treating various skin conditions, including acne, eczema, psoriasis, and skin cancer. Dermatologists are qualified to perform procedures such as biopsies, surgeries, and laser treatments. They are also trained to provide cosmetic treatments for improving the appearance of the skin. Therefore, a dermatologist is the correct answer in this case as they specifically focus on the health and well-being of the skin, hair, and nails.

Hair loss is more common in men compared to women. This is due to several factors such as hormonal differences, genetics, and the presence of androgen hormones. Male pattern baldness, also known as androgenetic alopecia, is the most common type of hair loss in men. It is characterized by a receding hairline and thinning of hair on the crown area. While women can also experience hair loss, it is generally less frequent and often related to hormonal changes, medical conditions, or certain medications.

Alopecia is the correct answer because it is the general term used to describe a variety of hair problems, including abnormal hair loss, balding, or reduced hair density. Male pattern baldness and Tinea capitis are specific conditions that fall under the umbrella term of alopecia.

Postpartum alopecia refers to temporary hair loss that occurs after giving birth. During pregnancy, hormonal changes cause an increase in hair growth and thickness. However, after delivery, these hormonal levels drop, leading to a shedding of hair. This shedding typically begins around three months after childbirth and can last for several months. Postpartum alopecia is a common condition that affects many women, but the hair loss is temporary and the hair usually regrows within a few months. It is important to note that postpartum alopecia is different from other forms of alopecia, such as alopecia areata or androgenetic alopecia, which are not related to pregnancy.

Traction alopecia occurs when the hair is pulled too tightly, causing damage to the hair follicles. This can be caused by hairstyles that put constant tension on the hair, such as tight ponytails, braids, or extensions. Over time, this constant pulling can lead to hair loss in the affected areas. Unlike other types of alopecia mentioned, traction alopecia is specifically caused by external factors and can be prevented by avoiding hairstyles that cause excessive pulling and tension on the hair.

During the anagen phase of the hair life cycle, the hair follicles are actively producing new hair cells. This is the period of hair growth, where the hair shaft extends from the follicle and continues to grow longer. The anagen phase can last for several years, and the length of this phase determines how long the hair can grow. It is the longest phase of the hair cycle and is followed by the catagen and telogen phases, where the hair follicles shrink and the hair eventually falls out.

Telogen is the correct answer because it refers to the shedding phase of the hair life cycle. During this phase, the hair follicle is at rest and the hair strand is no longer growing. It is in a dormant state before it eventually falls out and is replaced by a new hair strand. This phase typically lasts for a few months before the cycle repeats itself.

Canities is the correct answer because it refers to the loss of natural pigment or melanin in the hair, resulting in gray hair. Traction alopecia refers to hair loss caused by excessive pulling or tension on the hair, while hypertrichosis refers to excessive hair growth.

Pustules are small white pimples that seep pus. They are a type of acne lesion that forms when the pores become clogged with dead skin cells, bacteria, and oil. The body's immune response causes inflammation, leading to the formation of a pustule. Pustules are typically filled with a yellowish or whitish fluid, which is a mixture of dead skin cells, bacteria, and white blood cells. They can be painful and may leave behind scars if not treated properly.

Congenital canities refers to a hair disease or disorder where graying of the hair occurs at or before birth. This condition is present from birth and is not acquired later in life. It is characterized by the premature graying of the hair, which can be caused by genetic factors or certain medical conditions. Unlike acquired canities, which refers to graying of the hair that develops later in life, congenital canities is present from the beginning.

Minoxidil is a topical medication that is applied to the scalp twice a day. It has been scientifically proven to stimulate hair growth. This medication is commonly used to treat male pattern baldness and can also be used to promote hair regrowth in women. Minoxidil works by widening blood vessels and opening potassium channels, which allows more oxygen, blood, and nutrients to reach the hair follicles. This, in turn, can lead to increased hair growth and thickness.

The lower the number on the pH scale, the more acidic. This is because the pH scale measures the concentration of hydrogen ions in a solution. A lower pH value indicates a higher concentration of hydrogen ions, which makes the solution more acidic.

The correct answer is epidermis because it is the outermost layer of the scalp. The epidermis is the top layer of the skin, which covers the entire body including the scalp. It acts as a protective barrier against environmental factors and helps regulate body temperature. The epidermis also contains melanocytes, which produce melanin that gives color to the hair.

Hormonal imbalance can cause dandruff. Fluctuations in hormone levels can affect the oil production in the scalp, leading to an overgrowth of yeast that causes dandruff. Hormones play a crucial role in regulating various bodily functions, including the production of sebum, the natural oil that keeps the scalp moisturized. When there is an imbalance in hormones, it can disrupt the normal functioning of the oil glands, resulting in a dry and flaky scalp. This imbalance can be caused by factors such as puberty, pregnancy, menopause, or certain medical conditions.

Pityriasis is the correct answer because it refers to the accumulation of large, visible clumps of scales on the scalp, commonly known as dandruff. Pityriasis is a condition that affects the epidermis, which is the outermost layer of the skin. It is often caused by an overgrowth of a yeast-like fungus called Malassezia. This overgrowth leads to the shedding of excessive skin cells, resulting in the formation of dandruff. Therefore, pityriasis is the appropriate term to describe this condition.

Seborrheic dermatitis is a skin condition caused by inflammation of the sebaceous glands. It is characterized by symptoms such as redness, dryness, oily scaling, crusting, and itching. These symptoms are similar to wet dandruff, which is why seborrheic dermatitis is the correct answer. Pityriasis capitis simplex and pityriasis steroids are not correct answers as they do not accurately describe the given symptoms.

Finasteride is an oral prescription medication specifically designed for men. It is used to treat male pattern baldness and enlarged prostate. If taken by women, it can lead to serious birth defects in unborn babies. Therefore, it is important for women to avoid using finasteride to prevent any potential harm to the fetus.

Miniaturization refers to a condition of the hair follicle where long, thick, and pigmented hair strands are replaced by short, thin, and unpigmented hair. This process is commonly seen in androgenetic alopecia, also known as male or female pattern baldness. It occurs due to the shrinking of hair follicles over time, leading to the production of smaller and weaker hair strands. This ultimately results in the thinning and loss of hair in affected areas.

Alopecia universalis refers to a condition where there is complete hair loss on the scalp and body. This condition is considered an advanced form of alopecia areata, which is characterized by patchy hair loss. In alopecia universalis, the immune system mistakenly attacks the hair follicles, leading to their destruction and subsequent hair loss. Unlike other types of alopecia, which may only affect certain areas of the body or scalp, alopecia universalis results in the loss of all body hair.

When there is an overgrowth of the fungal yeast called malassezia on the scalp, it can lead to the appearance of dandruff. Malassezia is a common type of yeast that is naturally present on the skin. However, certain factors such as hormonal changes, stress, or a weakened immune system can cause an overgrowth of this yeast, leading to dandruff. This overgrowth can disrupt the normal balance of the scalp, resulting in flaking and itching.

Keloidal tissue refers to a thick scar that forms due to the excessive growth of fibrous tissue. This type of scar is characterized by its raised, firm, and smooth appearance. Keloidal tissue can develop as a result of various factors, such as trauma, surgery, or inflammation. It is often seen in individuals with a genetic predisposition to keloid formation. The excessive growth of fibrous tissue in keloids can cause discomfort, itching, and cosmetic concerns. Treatment options for keloidal tissue include corticosteroid injections, surgical removal, and laser therapy.

The correct answer is lack of proper cleansing. Dandruff can occur when the scalp is not cleaned regularly or thoroughly. Improper cleansing can lead to a buildup of oil, dead skin cells, and product residue on the scalp, creating an environment for the overgrowth of a fungus called Malassezia. This fungus can cause irritation and excessive shedding of skin cells, resulting in dandruff. Therefore, maintaining good scalp hygiene and regularly washing the hair can help prevent dandruff.

Acquired canities refers to a hair disorder where graying of the hair is caused by the aging process. This means that the individual's hair turns gray naturally as they get older. It is not a congenital condition, which means it is not present from birth. Other options like ringed hair, hypertrichosis, trichoptilosis, trichorrhexis nodosa, monilethrix, and fragilitas crinium do not specifically relate to graying of the hair due to aging.

Seborrheic dermatitis is the most common scalp disorder that a natural hair stylist can recommend treatments for. This condition is characterized by red, itchy, and flaky patches on the scalp. It is caused by an overproduction of oil and a yeast called Malassezia, which leads to inflammation. Natural hair stylists can recommend treatments such as medicated shampoos, essential oils, and natural remedies like apple cider vinegar or aloe vera to help manage and alleviate the symptoms of seborrheic dermatitis.

Tinea capitis refers to a fungal infection of the scalp, commonly known as ringworm of the scalp. It causes hair loss and can result in patches of baldness. Alopecia, on the other hand, is a general term for hair loss and is not specific to a fungal infection. Tinea favosa is a type of fungal infection that affects the scalp, but it is characterized by the formation of yellow crusts or scutula, which is not mentioned in the question. Pediculosis capitis is a condition caused by head lice infestation and does not involve a fungal infection. Therefore, the correct answer is tinea capitis.

Many commercial dandruff shampoos contain tar solutions that cosmetically and temporarily address the problem. Tar has antifungal and anti-inflammatory properties that help reduce dandruff symptoms such as itching and flaking. However, these shampoos only provide temporary relief, and regular use is required to maintain the results.

The average life cycle of a hair strand is estimated to be between 4 to 6 years. This means that on average, a single hair strand will grow, rest, and shed over a period of 4 to 6 years before being replaced by a new hair strand.

Ringed hair refers to a hair condition where the hair shaft has alternating light and dark bands or rings. This can be caused by various factors such as changes in hair pigmentation or damage to the hair shaft. It is different from other hair disorders listed, such as congenital canities (premature graying of hair), acquired canities (graying of hair due to aging or other factors), hypertrichosis (excessive hair growth), trichoptilosis (split ends), trichorrhexis nodosa (brittle hair), monilethrix (beaded hair), and fragilitas crinium (hair breakage).

Larkspur tincture can be advised to the client to apply to the entire head before bedtime in order to kill head lice.

Androgenetic alopecia is the correct answer because it is commonly known as male pattern baldness. This condition is characterized by hair loss in a specific pattern, typically starting at the temples and crown of the head. It is caused by a combination of genetic and hormonal factors, with dihydrotestosterone (DHT) playing a significant role. Androgenetic alopecia can affect both men and women, although it is more common in men. It is a progressive condition that can lead to complete baldness in severe cases.

Trichoptilosis is the correct answer because it refers to the technical term for split hair ends. Trichoptilosis occurs when the hair cuticle becomes damaged, causing the hair to split and become frayed at the ends. This condition is commonly caused by excessive heat styling, chemical treatments, or rough handling of the hair. Trichoptilosis can make the hair appear dull, damaged, and unhealthy.

Diffuse alopecia is the most appropriate answer because it refers to a condition where there is widespread hair loss on the head. This condition is often sudden and affects young females, which aligns with the given information. Inflammatory response and alopecia totalis do not accurately describe the specific characteristics mentioned in the question.

Tinea favosa is a type of honeycomb ringworm that is characterized by a dry sulfur yellow cuplike crust on the scalp. This condition is caused by a fungal infection and can lead to hair loss and scarring if left untreated. It is important to seek medical treatment for tinea favosa to prevent further complications and to effectively eliminate the infection.

Alopecia areata is a condition characterized by sudden hair loss in patches or spots. It is an autoimmune disease where the immune system mistakenly attacks the hair follicles, resulting in hair loss. This condition can affect any hair-bearing area of the body, including the scalp, eyebrows, and beard. Unlike other types of alopecia, such as androgenetic alopecia which is hereditary, alopecia areata is not caused by genetics. It is believed to be a combination of genetic and environmental factors that trigger the immune system to attack the hair follicles.

The correct answer is Guanidine hydroxide and sodium hydroxide. These two chemicals are commonly used in hair straightening products. Guanidine hydroxide is a strong alkali that breaks the disulfide bonds in the hair, allowing it to be reshaped. Sodium hydroxide, also known as lye, is another strong alkali that works in a similar way to guanidine hydroxide. Both chemicals are effective in straightening hair, but they can also cause damage if not used properly.

Trichorrhexis nodosa is the correct answer because it refers to a dry, brittle condition of the hair that includes the formation of nodular swellings along the hair shaft. This condition is characterized by weak points in the hair shaft, leading to breakage and the formation of knots. The term "trichorrhexis" means hair breakage, and "nodosa" refers to the nodular swellings. Therefore, trichorrhexis nodosa accurately describes the described condition.

The catagen phase is the correct answer because it is the transitional phase between the active growth phase (anagen) and the resting phase (telogen) of the hair life cycle. During catagen, the hair follicle shrinks and detaches from the blood supply, causing the hair to stop growing. This phase typically lasts for a few weeks before the hair enters the telogen phase, where it remains in a resting state before eventually shedding and being replaced by a new hair.

The correct answer is "Inflammatory response." Inflammatory response refers to the body's reaction to perceived threats or damage, which includes releasing chemicals and immune cells to the affected area. In the case of the scalp, when the body identifies an area as a threat, it initiates an inflammatory response that can lead to the destruction of the hair follicle. This can result in conditions such as hair loss or alopecia.

Monilethrix is a technical term for beaded hair, where the hair breaks between beads and nodes. This condition is characterized by the presence of multiple nodes or constrictions along the hair shaft, giving it a beaded appearance. It is a genetic disorder that affects the structure of the hair shaft, leading to increased fragility and breakage. The term "monilethrix" is derived from the Latin words "monile" meaning necklace and "thrix" meaning hair, which accurately describes the appearance of the hair in this condition.

Hypertrichosis is a hair disease or disorder characterized by abnormal development of terminal hair, leading to excessive and superfluous hair growth. Unlike other options listed, hypertrichosis specifically refers to the condition of excessive hair growth, which can occur either congenitally (congenital hypertrichosis) or later in life (acquired hypertrichosis). Therefore, hypertrichosis is the correct answer in this context.

Pediculosis capitis refers to the infestation of the hair and scalp with head lice. This condition is characterized by the presence of lice eggs (nits) attached to the hair shafts, as well as the presence of adult lice. It is a common problem, especially in children, and is spread through close contact with an infested individual or by sharing personal items such as combs or hats. Symptoms of pediculosis capitis include itching, redness, and the presence of small red bumps on the scalp. Treatment typically involves the use of medicated shampoos or lotions to kill the lice and their eggs.
