How to avoid hairfall? anyidea?

Not sure if you mean preventing going bald but, overall you can expect to be shedding 50-100 hair follicles on a daily basis. This is the normal amount of hair a healthy scalp can except to lose on a daily basis. If your hair is falling out in clumps, in your shower drain or your hair brush then it's time you should see a doctor.

Hope this helped! :)
