At any given point of time, between 85-90% of the hair on scalp of both men and women is in growing stage. Around 10-15% of the hair on your scalp is in resting stage. Hair in resting stage tend to remain in this stage for a period of 2 to 3 months after which they fall out and new hair grows in its place. This is a normal development cycle of healthy men and women.
During this cycle, it is absolutely normal for hair in the resting stage to fall out. Some people shed upto 100-125 hair a day which is quite normal. That’s because the lost hair is reproduced. However, some people may experience more than normal hair loss that can affect children, men and also women of any age group.
So, if you shed upto 100 hair a day and do not see any change in the density of the hair on your scalp, there is nothing to worry about. Your hair is reproducing. However, if you are experiencing sudden hair loss, you should consult a doctor immediately.
