Im sorry to read you have to be going through this. Im wondering if you have changed hair products or hair dyes in the last few months? A new hair brush? If not, this could be down to medication and i would let your Doctor know anyway.He can help you. With many of the meds you take, it is normal for hair to start thinning.But it doesnt mean your hair will fall out. Also, as you get older its very normal for hair,eyebrows,lashes to fall out natrually. They will and do grow back. If you tie your hair up, say in a pony tail, when you take your hair down, you will notice more hair than normal falling out.Aspecially then if you wash it.This is because, if your hair was down, the wind would blow away any hair that natrually falls out and you never notice.But when tied up, you are stopping that process and its a big worry when washing your hair to find what looks like clumps falling when really, its normal. You are supposed to loose 150 hairs a day. When my hair was long, i lost about 450 hairs a day I have extremely thick hair and curly yak!
I know its not easy to go through, so let your doctor know and he will help you with solutions that can go on your scalp, like a medicated shampoo and stuff.
Hope this helps a little.
