welcome to healthcare magic forum
thank you for your query
you are really concern about your future hair also .
has side effect of hair loss ,but it do not cause thinning of hair .
happen in all scalp
in donor area also ,but it is temporary .
we have to see the risk benefit ratio,if it is compulsory to use roaccutane continue it for short time and if not needed than stop it .
i hope i answered your question
