How Hormones Affect Hair Health in Men and Women

Hair health is influenced by many factors — nutrition, genetics, stress, and lifestyle — but few play as significant a role as hormones. These powerful chemical messengers regulate growth cycles, oil production, and even the thickness of each strand. When hormones fluctuate or fall out of balance, it can directly lead to thinning, shedding, or pattern baldness in both men and women.

The Role of Hormones in Hair Growth

Each hair follicle goes through a cycle of growth, rest, and shedding. Hormones such as androgens, estrogen, and thyroid hormones help regulate this cycle. When these hormones shift — due to age, medical conditions, or stress — hair follicles can become weaker or dormant, leading to visible hair loss.

• Androgens (Testosterone & DHT):
  In men, the conversion of testosterone into dihydrotestosterone (DHT) is one of the main causes of male pattern baldness. DHT binds to hair follicles, shrinking them over time and shortening the growth phase.
• Estrogen and Progesterone:
  In women, higher estrogen levels during pregnancy often make hair fuller and shinier. However, postpartum or during menopause, estrogen levels drop, causing increased shedding and thinner hair density.
• Thyroid Hormones:
  An underactive (hypothyroid) or overactive (hyperthyroid) gland can cause brittle hair or diffuse hair loss. Balancing thyroid hormones is often key to restoring natural growth.

Hormonal Hair Loss in Men vs. Women

Men typically experience receding hairlines and bald spots caused by androgenetic alopecia. Women, on the other hand, notice overall thinning — especially around the crown and part line — often due to hormonal changes related to pregnancy, menopause, or contraceptive use.
