An explaination of why I cut 5 inches off my hair a couple weeks ago when I was previously trying to grow it out...
Sandra Johnson, dermatologist, says:
All new moms experience hair loss, though some lose more than others.
Here's why it happens. During pregnancy, changes in your hormone levels cause your hair to stay in a resting phase for longer, so you lose less hair on a daily basis. (You may have noticed that your hair seemed thicker than usual.)
After you've given birth and your hormones have settled down — usually at about 12 weeks after delivery — more hair shifts into a shedding phase. You may be alarmed to find hair coming out by the handful.
Normally, you lose about 100 to 125 hairs a day, but after delivery, you may be losing about 500 a day. This can be very disturbing, but try not to worry too much — you won't go bald!
