Question

Why in winter the rate of hair fall is maximum as compare to other seasons?

Answer 1

It depends from person to person.

In winter some people may face hair fall as their hair becomes dry while some people may face hair fall during summer due to humidity.

Answer 2

My pets usually lose their hair in the spring, rather than in the winter. This is so that their coat can be thinner in the summer. I don't know what the situation is for humans.
