Hormones play a crucial role in regulating hair growth. In the study of HEALTH AND SKINCARE / SOMATOLOGY / BEAUTY AND NAILS / HAIR AND BEAUTY / COSMETOLOGY, we learn that the balance and interaction of various hormones influence the growth, thickness, and patterns of hair on different parts of the body.
Here are some key hormones that impact hair growth:
- Androgens:
- Androgens are male sex hormones that are responsible for stimulating the growth of terminal hair (coarse, pigmented hair) in areas such as the face, chest, and genital region.
- Estrogen:
- Estrogen is a female sex hormone that plays a role in hair growth.
- Progesterone is another female sex hormone that, in combination with estrogen influences hair growth.
- Insulin and Insulin-like Growth Factor-1 (IGF-1):
- Insulin, a hormone with growth-promoting effects, can influence hair growth.
- Thyroid Hormones (T3 and T4):
- Thyroid hormones play a role in metabolism and can influence hair growth.
- Cortisol:
- Elevated levels of cortisol due to chronic stress can contribute to hair loss.
- Prolactin:
- Elevated prolactin levels may be associated with hair loss in some cases.
- Melatonin:
- Melatonin may also have an impact on hair growth.
- DHEA (Dehydroepiandrosterone):
- Changes in DHEA levels may influence hair growth.
Hormonal imbalances, whether due to natural fluctuations, medical conditions, or external factors, can lead to changes in hair growth patterns. Should you wish to study HEALTH AND SKINCARE / SOMATOLOGY / BEAUTY AND NAILS / HAIR AND BEAUTY / COSMETOLOGY, you will learn that conditions such as androgenetic alopecia (genetic hair loss), PCOS, and thyroid disorders are examples of conditions where hormonal influences play a role in hair-related issues. If someone is experiencing significant changes in hair growth or hair loss, it is advisable to consult with a healthcare professional or a dermatologist for a thorough evaluation and appropriate guidance.
