Dear all, I've been wondering about my sudden hair loss, I have never had an issue with losing hair (only opposite issues) and after numerous blood tests I know it's not hormonal or hereditary. I underwent coloring and a keratin treatment 2 months ago and I'm afraid it is the culprit. Are there any treatments/products that could reverse the damage or wash the keratin out of my hair? Have any of you heard/experienced keratin caused hair loss? My hair is very thin especially on the top.Thank you.
