How DHT Affects Hair Loss & How 826 Helps 

Discover how DHT affects hair follicles and how 826 helps block androgen signaling to support healthier follicles, a longer growth phase, and healthier hair growth.
1

Product efficacy

KOSHINE’s patented core ingredient, 826, is an androgen receptor antagonist. By competitively inhibiting the binding of dihydrotestosterone (DHT) to androgen receptors in target tissues, it helps block DHT–androgen receptor activity, allowing hair follicle cells to return to a healthier state. It also helps improve sebaceous gland hyperplasia and excessive scalp oil production, thereby supporting oil control, hair-loss prevention, and protection against baldness. Full name of 826: Methylpyridinyl Fluoromethoxybenzonitrile Dimethyloxothiooxoimidazolidine

Mechanism of Action

Research indicates that hair follicles affected by androgenetic alopecia are more sensitive to dihydrotestosterone (DHT). DHT binds to androgen receptors, causing follicle miniaturization, shorter growth cycles, thinner hair, and eventually hair loss. This process is often accompanied by increased scalp oil production. 826 is an androgen receptor antagonist that competitively blocks DHT from binding to androgen receptors, helping reduce androgen-related effects on hair follicles. With consistent use, it may help support healthier follicles, reduce hair loss, extend the growth phase, and promote a healthier hair-growth cycle.

Experimental Data

According to the clinical trial report, 826 demonstrated favorable efficacy and safety. In the 0.5% twice-daily (BID) treatment group, the target area’s non-vellus hair count increased by 22.73 hairs/cm² from baseline after 24 weeks of treatment. Some participants observed visible hair regrowth as early as Week 6.
