Accutane - Hair Loss? Question for Male Accutane Users

Hello- my husband has had severe acne his entire teenage and adult life. I am trying to convince him to try accutane, as it completely transformed my skin years ago.

For the men who have been on accutane, did you experience any hair loss? If so, was it permanent?

Also, any major weight changes or other long term negative side effects that he should consider?

Thanks in advance.
