The hair loss can seem more extreme if your hair grew much more than normal during pregnancy, or if you have long hair. Most women will return to their usual hair growth cycle within six months, or between 6 and 12 months after birth.

Other possible causes for excessive hair loss, thinning, or breakage include: Damage to the hair from hair care products, such as dyes and permanents, and from hot rollers, curling irons, or hair dryers.
