Hair Loss & Hair Color

Hello All!   I actually have 2 questions for everyone .... for those who have had hair loss after surgery, was there anything that helped reduce the amount of hair that you lost after it began to thin? ( I have since increased my protein intake and have been taking the suplment Biotin, seems to be helping a little) Second question, my grey hairs are getting really bad and I am in desperate need of hair coloring ... has anyone colored their hair after their hair loss began and what were the results?

I am affraid that if I color my hair, it will add more stress to my scalp ( it already is super sensative from the loss of hair) and cause it to fall out more!  Any reccomendations??

I'd love to hear more on this too - I am almost 5 months post-op and losing a lot of hair.  I dont have any really thin spots but I run my hand through and pull out a LOT of hair, it reminds me of that post-partum shed you usually go through but worse.  I dont know how long this should last, how much to worry, etc.  I have heard of the Biotin but havent tried it.  Michelle
