🔬 What Is DHT, and Why Does It Matter?
Dihydrotestosterone (DHT) is a hormone derived from testosterone.
While it's essential for male development, it’s also the primary cause of male-pattern baldness — known medically as androgenic alopecia.
When DHT binds to hair follicle receptors, it causes them to shrink over time, producing thinner and shorter hairs, and eventually halting growth altogether.
According to a 2020 study in the Journal of Dermatology, over 80% of men and 40% of women experience DHT-related hair thinning by the age of 50.
🧪 How DHT Inhibitors Work
There are two types of DHT blockers:
-
Internal (Systemic): These include medications like Finasteride and Dutasteride, which inhibit the 5-alpha-reductase enzyme responsible for converting testosterone to DHT.
-
Topical: Shampoos and serums containing ketoconazole, saw palmetto, or pumpkin seed oil have shown localized DHT-blocking effects.
A double-blind placebo-controlled study in 2014 showed that saw palmetto improved hair density in 60% of participants after 24 weeks.

✅ Effective For:

Women with PCOS-related hair loss

Early-stage androgenic alopecia
❌ Avoid If:
