Peat Archive

Ray Peat approached hair loss as a metabolic and hormonal problem. He argued that the conventional focus on DHT (dihydrotestosterone) misses the larger picture: hair follicles require adequate thyroid function, good circulation, and proper hormonal balance. Hypothyroidism is one of the most common causes of hair loss, and restoring thyroid function often improves hair growth.

Peat also noted that progesterone opposes the hair-damaging effects of cortisol and excessive androgens, and that reducing stress, improving nutrition, and addressing hormonal imbalances are more effective long-term strategies than anti-DHT drugs.
