I was told on Monday that I have androgenic alopecia. Devastating at any age and definitely not something I thought I'd be dealing with at 33. I've been offered a scalp biopsy to be sure and I was wondering if anyone has had one. If so, could you let me know where they take the hair from? I don't want it taken from my thinning bits. I know it would only be a small bit taken away but every hair counts!!
