The average person tends to lose 50-100 strands a day. People with shorter or thinner hair tend to shed less than longer-haired individuals. Long-haired individuals lose around 150-200 strands of hair on the washing day. The fallen hair can regrow if the follicle is still intact. But if the follicle has closed or is scarred, new hair does not grow in its place. There are two simple tests to determine whether you have abnormal hair fall:   Comb test  You must comb your hair from the back of your head to the front of the scalp and then count the hair strands lost during the combing process. Loss of more than 10-15 strains indicates abnormal hair fall. Pull test  Approximately 60 strands of hair are taken between the fingers and gently pulled. 5-8 strands of hair in the fingers are standard, but 15-20 are abnormal.
