I'm sure it is very normal for people to lose 100-150 hairs per day, that is for people who don't suffer from mpb. The problem with our situation is that the hairs grow back very tiny and wispy and eventually never at all, wheras people with healthy scalps grow back long healthy hairs. Our problem lies with hairs not growing back -- 150 hairs multiplied by 365 days a year = over 50,000 hairs, yikes!!!!
