Question

1. what are three specific internal and external factors that can affect hair health? 4. imagine one of your clients asks you if diet supplements or other changes to their diet can serve as a “quick fix” to improve the health of their hair. what will you tell them? 5. what role do androgens and thyroid hormones play in the loss or thinning of hair? 6. list three examples of styling techniques, processes, or tools that might harm hair. minoxidil a topical medication, scalp, a hair transplant, can assist clients with non - surgical options to counter hair loss wigs

Explanation:

1. Internal factors: Hormonal imbalances (e.g., high - androgens can cause androgenetic alopecia), nutritional deficiencies (lack of biotin, zinc), genetic predisposition. External factors: Harsh hair products (containing sulfates), excessive heat styling (using flat - irons), environmental pollutants.
2. Explain that diet supplements alone are not a quick fix. Hair health is a result of overall health. A balanced diet rich in vitamins (like B - vitamins, vitamin E), minerals (iron, selenium), and proteins is crucial. Also, lifestyle factors like stress management and proper sleep play important roles.
3. Androgens, especially dihydrotestosterone (DHT), can bind to hair follicle receptors, causing miniaturization and eventually hair loss in androgenetic alopecia. Thyroid hormones regulate metabolism and cell growth. Hypothyroidism or hyperthyroidism can disrupt the hair growth cycle, leading to hair loss or thinning.
4. Tight braiding can cause traction alopecia over time. Using hot combs at high temperatures can damage hair shafts. Chemical relaxers can break down hair proteins and lead to hair breakage and thinning.
