But this atRAS level being high is something permanent or something that subside with time?
Accutane itself is proven to cause diffuse hairloss through tellogen effluvium
by what u said we can conclude that, accutane can induce hairloss and by inducing hairloss it can worsen AAG what is evident, everything that cause hairloss will worsen the aag state of a person, meaning that the hairs that felt maybe wont comeback because theyre being attacked by DHT while they fall for another reason beside dht
i didnt understand right but u said that accutane can induce alopecia areata too?
Yes on studies it tells that it can change permanently the genes expression in the cells. Means that the aldh1a3 (who is transforming enzymes in atRAs and so determinate the level of atRA) will be more active for life longterm
then it depend on how strong accutane alterated our RA metabolism. Every metabolism react in different proportion. Maybe it's possible that the atRAs are really high for the first years post accutane and then decreased, but still if it's too high it will have the negative conséquences. they say on the studies that precise level is really important for evertyhing work well about the hair follicle
In my case, since accutane I never see one little white sebum acne again for years, my skin never react the same as before under the sun (more sunburns and more difficult to tan (tan process is related to the ALDHs family!), so I'm pretty sure accutane have done his 'job' well in my skin cells
For your last question, no alopecia areata and universalis are non cicatricial alopecias
Alteration of the vitaminA metabolism is linked to cicatricial alopecias (CCCA, PCA, LLP, FFA), a kind of inflammation that destroy the follicle and the stem cells. Look in the msg, i put the different studies that explain how altered vitA metabolism (higher RA metabolism activity) lead to hair destruction ( less wnt, less anti inflammation protectors, less growth factors, etc)
And this can work in synergy with the Androgenetic Alopecia factors, all of that kill the follicles faster logically
