It depends whether your hair texture strong enough? Some ppl lose 10-20 strands when they comb, overall per day would be average 20 strands ( if i'm not mistaken )

My tips is, try to use shampoo that has the ingredient of "BIOTIN". It prevent minor hair loss and also hair breakage problem. Generates hair growth, those who wants their hair to grow faster, try this ingredient. So far, I came across the Schwarzkopf shampoo that has this ingredient! Can purchase it in Guardian or Watson. Color is White bottle with the cap in brown.

Hope this help! ^_*
