Can You Explain Hair Loss from Amphetamines?

On a molecular level, how do ampetamines cause hair loss and how can this drug induced hair loss be halted or reversed? Thank you for you time.

I really do not know the answer to your question. My previous posting reflected what is known by the manufacturers of the various amphetamines and from others that have suffered from this hair loss side effect. I am sure that the answer is intricate and related to many other factors in those particular people taking the drug.
