The answer you will mostly get from us will be Nizoral. That shampoo is a must for anyone juicing. Some people will recommend Nioxin too but it's really expensive. If you're worried about your hair do a search. It's been talked about alot on these forums.
get some polysorbate 80 too, the stuff is really great. its the only treatment i use every single day. it wont reverse hairloss but it will help greatly in keeping what you got. the nizoral is a good idea too.
This combined with polysorbate 80, left on all night is giving me no more shedding and much thicker hair. I have also got new hair not just the baby type hairs. I have even got a no.2 hair cut without worrying.
