Does hair lost with white bulb grow back? or is it a sign of telogen effluvium or male pattern baldnes ( i loose like below 100 hairs per day?) is it normal?

I refer patients, especially young ones, who have questions about their hair loss, to a dermatologist. This will ensure that the scalp will be examined for pathology, that any tests deemed appropriate will be ordered and the patient will be told what type of hair loss is present and whether it will regrow. Also any treatment options or preventative measures will be discussed.
