Wigs? does it really get that bad?
I too have very long hair. I've been taking biotin and scheduled for sugery in 6 days.
Try not to stress because I know from personal experience stress can make it very bad.
I don't know if i would go so far as a pixie cut (personally) from long hair unless that's something you've always wanted but shorter hair will definately take the weight of and common sense says it will help. IMHO.
I hope it improves.
