I would seriously doubt either fin or dut would prevent any Hair loss caused by accutane as both only help to block the conversion from test to DHT, and the mechanism by which accutane can cause Hair loss is totally different.

Accutane is essentially megadosed Vitamin A. This high dose Vitamin A basically shuts down the oil glands and cures any acne problems one may suffer from. Unfortunately, it's this high dose of Vit A which is responsible for any potential side effects.

The one positive note is that any Hair loss resulting from accutane use is generally reversible (unlike MPB). If you did happen to experience the dreaded Hair loss side effect, you could discontinue use and have a great chance of growing back any lost hair.

Agreed, I think finasturide or dutasteride will only work for hairloss due to AAS.

I thought it might be different.

Is hairloss on accutane dose dependant or individual? Also, what's the most common dose and duration?

I would think it would be more of an individual thing as you should start off at a low/mid range dose to begin with so early on you'll be able to tell if Hair loss might possibly become a concern.

As for the dose, I know that it varies according to bodyweight. A 200 lb person would start off somewhere around 40mg/d in divided doses. It is usually run for a duration of 4-6 months I believe.

Have you already tried topicals such as clindamycin or benzamycin or internals such as tetracycline or doxycycline? I've used just topical clindamycin for quite some time and I find that it works extremely well. No acne whatsoever (well part of that is the fact that I haven't cycled in well over a year...LoL)

even if you are prone to mpb, i highly doubt you have anything to worry about with accutane brolly. I don't think i ever heard of anyone thinning or even losing small amounts of hair on it. I wouldn't run dut/propecia just for the sake of running accutane cause the side affects of dut and so forth out way any effects from accutane in imo.
