Hairsite is a waste of time. It has outdated info on the main pages and promotes very dubious doctors. On the forums themselves there is nothing of value to learn; a lot of needless bitching. There are some genuine posters but they are jumped on by the mob; as jototronic he has sufferred there when all he was doing was giving advice to some posters. There are also many fake posters there who either lie about great results from avodart or dramatise the negatives. The moderator has no control as you dont have to register to post and can thus use diff names which adds to the confusion.
Hairlosshelp is a very good site and has many genuine posters. There is some conflict at times but it is usually honest debate gone a bit personal. I definitely reccommend this site as you will get an honest response. Arfy, jo and myself all post there regularly, although the two of them recently had a public falling out which i hope is now resolved. The only problem with the site is that its moderator, Farrel, intervenes in nearly every thread deletes posts and bans members at his discretion. That said he does seem to be a decent guy who wants to help people.
This site is very good but sometimes it can take days for someone to respond which can be frustrating but pats a good guy and its like a family here so i will always poat here. Hope this helps.
