My profuse hair loss lasted for four months before it slowed down. It does grow back in. I got the brown along with the gray. It did not come back healthier and shinier, etc. than before, it just came back as it was before. As such a huge quantity of my hair fell out at an incredible rate, the hair I managed to hold on to grew in length at an unprecedented rate. I had more hair cuts during this time than normal. Less hair but longer hair for the original. The new growth did not seem to grow as fast.

I'm just happy to have hair left.
