Association Between Stress-Related Hormone Levels in Hair and Subjective Mental Health in Japanese Workers

High DHEA levels may contribute to hair loss by increasing DHT in hair follicles, potentially explaining why finasteride is ineffective for some. Treatments like high-dose dutasteride and RU58841 are suggested, but the underlying cause, such as adrenal issues, should be investigated.

A 23-year-old male is considering starting Finasteride for hair loss after experiencing persistent shedding and hairline recession, with bloodwork showing normal testosterone levels but low DHEA-S and Vitamin D. He plans to discuss DHEA supplementation with his doctor and has already started Vitamin D supplementation.

The conversation discusses the hypothesis that a lack of the enzyme 3-alpha hydroxysteroid dehydrogenase (3α-HSD) on the scalp may contribute to hair loss by allowing DHT to accumulate. Despite interest in this theory, no recent research has been conducted, and current treatments like finasteride and minoxidil remain the most supported options.

Corticosterone inhibits GAS6, affecting hair follicle stem-cell activity, with potential implications for stress-related hair loss. Ashwagandha and Vitamin K are suggested for reducing cortisol, but their effectiveness is debated.

The user has been taking 1mg finasteride daily for a year with no improvement in hair loss and reports low cortisol levels, sleep issues, and anxiety changes. The conversation includes discussions on the potential effects of finasteride on cortisol and neurosteroids, with suggestions to consult a doctor and consider other factors.

Prolactin and cortisol are identified as key factors in hair loss, with stress hormones impacting hair shedding. Finasteride and minoxidil are effective treatments, while DHT's role and individual sensitivity are significant factors.
