How can accutane cause hair loss if it is rich in vitamin A which promotes hair growth?
The key to the answer is in your question: “accutane is a high dose of vitamin a”. And, in fact, high doses of Vit A cause marked shedding of the skin and the associated structures. Thus, if you were to take a very high dose of Vit A, your skin would turn a bright red, and you’d start shedding skin, hair, nails. The advantage of Accutane is that it, more often than not, gives the beneficial effects of high dose Vit A without the unwanted side effects. However, there are some people who also see some of the unwanted side effects, such as hair thinning.
