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?

in Finasteride/Dutasteride 26 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.

community 5ar alpha reductase stimulation is different depending on whether it’s type 1 or 2

in Hair Systems 17 upvotes 3 years ago

The conversation discusses how different factors can stimulate type 1 and type 2 isoforms of 5-alpha reductase, which are enzymes linked to hair loss. Specific treatments mentioned include oral Dutasteride and topical Finasteride.

community ghk-cu is potent 5-ar inhibitor?

in Product 10 upvotes 2 years ago

GHK-Cu is a potent inhibitor of the type 1 5-alpha reductase enzyme in hair follicles, which may reduce hair loss without the side effects associated with type 2 5-alpha reductase inhibitors. The user previously experienced side effects with 5-alpha reductase inhibitors and is considering GHK-Cu as an alternative.

community Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.

in Research/Science 9 upvotes 3 years ago

Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.

community Seeking Advice on Norwood 3 Hairline at Age 15

in Basic Questions 533 upvotes 8 months ago

A 15-year-old is concerned about hair loss, possibly at Norwood 2 or 3, and is using shampoos and conditioners recommended by a trichologist. Suggestions include considering topical minoxidil and consulting a doctor about topical anti-DHT treatments like finasteride or RU58841, but avoiding 5-alpha-reductase inhibitors at this age.
