scalp. The causes are many, including ringworm.
Causes of hair loss that don't require medical treatment
- Newborn hair loss. The hair of many newborns falls out
during the first few months of life. This baby hair is
replaced by permanent hair.
- Rubbing. Babies from 3 to 6 months of age commonly rub
off a patch of hair on the back of their head due to
friction during head-turning against the mattresses of
cribs, playpens, and infant seats. The hair grows back
once they start sitting up.
- Hair abuse. Hair can be lost because of vigorous
hairbrushing, hot combs, tight pony tails, or braids.
- Stress. Hair follicles are very sensitive to stress.

illness, a psychological crisis, a crash diet, surgery,
or even childbirth). The hair falls out from all parts
of the head over the next 3 or 4 months. After the hair
stops shedding, it takes another 6 to 8 months for all of
the hair to grow back. The whole cycle takes about
12 months. This type of hair loss is called telogen
