In about half of the affected children, these bald patches grow back over time, even without treatment. However, hair loss may also progress further and lead to the loss of all hair on the head (alopecia totalis). In the worst case, it can even lead to the loss of all body hair, such as the eyebrows, eyelashes, and pubic hair (alopecia universalis).
If your child is affected by circular hair loss, you should monitor the progress of bald patches weekly.
You can also wait for a while in case of minimal outbreak - i.e. small spots on the head that do not (yet) bother your child. As with adults, the progression is usually gradual. That is why it is an advantage if you take pictures of the spots to be able to judge the progress better. If these bald patches become larger or you are unsure, contact a local hair growth specialist. Because the sooner you react, the sooner the spook will be over.
