I had my surgery about 10 months ago and started losing my hair 6 months post-op. My hair was thick and curly and now its thin and the curl is not like it used to be. I started taking biotin, I'm using the OGX biotin and collagen shampoo and conditioner and now my husband got me the Spoiled Child biotin hair boost spray. I have baby hairs that have definitely grown in the last month, so maybe something is helping! I couldn't believe the amount of hair that came out in the beginning!! Thank god that only lasted about a month because I was scared I was going to have bald patches! For now I wear my hair up in a bun because I hate the way it looks when it is down.
