2.
Lasers use pulsating light beams to destroy the hair follicles.
Correct Answer
A. True
Explanation
Lasers are indeed used to destroy hair follicles. Laser hair removal works by emitting a concentrated beam of light that is absorbed by the pigment (melanin) in the hair follicles. This light energy is converted into heat, which damages the follicles and inhibits future hair growth. The pulsating nature of the light beam allows for precise targeting and controlled energy delivery, ensuring effective destruction of the follicles while minimizing damage to the surrounding skin. Therefore, the statement "Lasers use pulsating light beams to destroy the hair follicles" is true.
3.
Electrolysis is the only hair removal system considered permanent by the FDA.
Correct Answer
A. True
Explanation
Electrolysis is considered the only hair removal system that is recognized as permanent by the FDA. This means that it is the only method that has been proven to permanently remove hair follicles and prevent future hair growth. Other methods such as waxing, shaving, and laser hair removal may provide temporary results, but the hair eventually regrows. Electrolysis, on the other hand, uses a small electric current to destroy the hair follicle, preventing regrowth. Therefore, it is considered the only permanent hair removal option approved by the FDA.
4.
The cost of each treatment for electrolysis cost the same as a laser treatment.
Correct Answer
B. False
Explanation
The given statement is "The cost of each treatment for electrolysis cost the same as a laser treatment." The correct answer is False. This means that the cost of each treatment for electrolysis does not cost the same as a laser treatment.
5.
Electrolysis uses electric energy to destroy the hair follicles.
Correct Answer
A. True
Explanation
Electrolysis is a method of hair removal that uses electric energy to destroy the hair follicles. By inserting a tiny probe into each hair follicle, a small electric current is delivered, which damages the follicle and prevents future hair growth. This process is effective in permanently removing unwanted hair and is commonly used for areas such as the eyebrows, chin, upper lip, and bikini line. Therefore, the statement "Electrolysis uses electric energy to destroy the hair follicles" is true.
6.
Galvanic current uses AC current.
Correct Answer
B. False
Explanation
Galvanic current actually uses DC (direct current) rather than AC (alternating current). DC current flows in one direction only, while AC current alternates its direction periodically. Galvanic current is commonly used in electrotherapy and skin treatments, such as iontophoresis and galvanic facials, where a low-level constant current is applied to the skin to enhance product penetration or stimulate muscles.
7.
Lye is produced from the sebum in the follicle.
Correct Answer
B. False
Explanation
False.
Lye is not produced from the sebum in the follicle. Lye, also known as sodium hydroxide (NaOH), is a chemical compound that is typically produced through the electrolysis of sodium chloride (salt) solution. It is commonly used in soap making, cleaning, and various industrial processes.
Sebum is a natural oily substance produced by sebaceous glands in the skin. It helps to lubricate and protect the skin and hair, but it is not related to the production of lye.
8.
Laser and IPL is considered Permanent Reduction of hair growth.
Correct Answer
A. True
Explanation
Laser and IPL (Intense Pulsed Light) treatments are commonly used for hair removal. These procedures work by targeting the hair follicles with concentrated light energy, which damages them and inhibits future hair growth. While these treatments are often referred to as "permanent hair reduction" rather than "permanent hair removal," they are generally effective in significantly reducing hair growth over time. Therefore, the statement that Laser and IPL is considered Permanent Reduction of hair growth is true.
9.
Pathogenic Bacteria is good bacteria.
Correct Answer
B. False
Explanation
Pathogenic bacteria are not considered good bacteria because they can cause diseases and harm to the host organism. Good bacteria, on the other hand, are beneficial to the host organism and play important roles in various biological processes such as digestion, immunity, and synthesis of vitamins. Therefore, the statement that pathogenic bacteria are good bacteria is false.
10.
Hirsutism is excessive hair growth all over the body like the wolf man.
Correct Answer
B. False
Explanation
Hirsutism is not excessive hair growth all over the body like the wolf man. Hirsutism refers to the growth of coarse, dark hair in areas where hair growth is typically seen in males, such as the face, chest, and back, in women. It is often caused by hormonal imbalances, such as an excess of androgens. The comparison to the wolf man is an exaggeration and does not accurately describe hirsutism. Therefore, the correct answer is False.
11.

Explanation
Vellus refers to short, fine, downy hair. This type of hair is usually unpigmented and covers most parts of the body, except for the palms, soles, and certain areas like the lips and genitals. Vellus hair is different from terminal hair, which is thicker, longer, and more pigmented. It is commonly found in children and can also be present in adults in certain areas, such as the face of women.
25.
What is hirsutism?
Correct Answer
B. Excessive hair growth
Explanation
Hirsutism refers to excessive hair growth in women, typically in areas where hair is normally minimal or absent, such as the face, chest, and back. This condition is often caused by an excess of male hormones called androgens. Hirsutism can be a result of various factors including hormonal imbalances, polycystic ovary syndrome (PCOS), certain medications, or underlying medical conditions. It is important to note that hirsutism is different from hypertrichosis, which is characterized by excessive hair growth all over the body.
26.
What causes a menopause mustache?
Correct Answer
C. Adrenocortical activity
Explanation
Adrenocortical activity refers to the functioning of the adrenal cortex, which is responsible for producing hormones such as cortisol and androgens. During menopause, there is a decrease in estrogen levels, which can lead to an increase in androgen levels. This hormonal imbalance can cause the growth of facial hair, commonly referred to as a "menopause mustache." Therefore, adrenocortical activity is the most likely cause of this phenomenon.
