What can cause a sudden large hair loss?
Cetain stresses to the system can result in sudden hair loss. for example, extreme weight loss or gain, pregnancy, severe illness, high fever or drug use can cause temporary hair loss. this is a result of the ratio between resting hairs and growing hairs shifting in favour of the resting hairs. When this happens, a greater quantity of normally sleeping hairs fall out. a dermatologist can normally ascertain the particular reason for this type of hair loss and full regrowth can be expected.
