Well, I don't know what to tell you about your hair returning to normal. I had my surgery over 8 years ago. At the time my hair was long and fine. I started taking Biotin before the surgery and still lost a good bit of hair. I had to get it cut short. I take 10000mg of Biotin daily and my hair has only improved slightly. Only difference I have seen since it started growing back was that it came back curly. I still have to keep it short and I guess that's just the way it's going to be for me. It is also very dry even though I use an intense condition twice a week. That was the one drawback for me but I still do not regret getting the surgery. I know it's very important to get your Protein in daily. That is something I struggle with because I don't have much of an appetite anymore. I guess my hair was collateral damage. Now, that's just me. Everyone's hair is different so don't despair. Keep taking your biotin and get a good conditioner and talk to your hairdresser for some advice. Good luck!!!
