In brief: Transitional hair
Newborn hair will usually fall out gradually over the first year & just as gradually be replaced with a thicker hair. It can be quite noticeable, producing a bald appearance, yet a close examination of the scalp shows emerging hair.Eyebrows & lashes are not affected during the process.
Some cultures appear less affected than others (darker hair<< lighter groups).

In brief: Alopecia universalis
Complete alopeecia is usually autoimmune.
It can be dealt with cosmetically in the short term, but i would see a dermatologist or immunologist. It often goes away, but in many cases not.
