Glossary Steroid 5 Alpha-Reductase 2

enzyme converting testosterone to potent androgen dihydrotestosterone (DHT)

Steroid 5 Alpha-Reductase 2 (also known as 5α-Reductase Type 2 or SRD5A2) is an enzyme that converts testosterone into dihydrotestosterone (DHT), a more potent androgen. This enzyme plays a crucial role in the development of male characteristics and is also implicated in conditions like male pattern baldness and benign prostatic hyperplasia.

community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?

27 upvotes 1 year ago

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

learn procapil

Want to stop hormonal hair loss without touching your hormone levels? Procapil could block the enzyme doing the damage. Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.

learn Fluridil

How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.

learn Omega 3

Is the omega-3 to omega-6 ratio in your diet feeding your hair problem without you knowing? Nutrition sources describe a lopsided omega-6 to omega-3 intake as pro-inflammatory, but no published human study shows that the dietary ratio changes 5-alpha reductase, scalp DHT or hair loss; the one relevant trial tested a commercial omega-3/6 plus antioxidant supplement in 120 women, not a change in dietary fat ratio.

learn Ecklonia Cava

Can Ecklonia Cava be used as a preventive treatment for early signs of hair thinning? No human trial has tested Ecklonia cava for hair loss, so it cannot be called preventive; the evidence is mouse studies and cell cultures suggesting antioxidant activity and 5-alpha-reductase inhibition in the lab.

learn Metformin

Does metformin help control DHT levels that trigger androgenic alopecia? Metformin has been shown to lower circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.
