when hair loss will stop ??

I think you are referring to hair fall post child birth or pregnancy, right? It actually depends from woman to woman, and in my case, while I had severe hair loss for about 2 years after delivery, in the second birth, my hair fall stopped about 6 7 months after delivery. I think a lot of this has to do with your overall health, what type of food you are eating and how much sleep you are getting.
