Just a thought. A book I have, called "Your Child's Health" has this to say:
Hair loss can occur in patches or throughout the scalp. The causes are many, including ringworm, which requires medical diagnosis and treatment.
Call your child's physician during office hours.
All children who have hair loss should be seen by a physician with the following exceptions:
- newborns ....
- babies from 3 to 6 months of age ...
- Hair can be lost because of vigorous hairbrushing, hot combs, tight pony tails or braids, or exercising while wearing headphones.
- Stress-related hair loss. Hair follicles are very sensitive to stress. The hair begins to fall out about 3 months (100 days) after a severe stress (such as a high fever, severe illnesses, psychological crisis, crash diets, or surgery) ... after about 12 months, the hair has stopped shedding and has returned to normal. Complete hair regrowth is the "rule".
I hope this helps.
