Does regrowth after telogen effluvium typically appear finer and lighter in color than the rest of hair?

In my opinion, the hair that grows back after telogen effluvium should be similar to your previous hair. It is possible that telogen effluvium can unmask a androgenic hair loss. This would lead to a decreased density. It is also possible that it may take a few cycles for the new hair to regrow with similar attributes to the lost hair. You should be evaluated by a hair expert. They will do a good magnified exam history and possibly blood work. The etiology of the change in your hair growth pattern will lead to a treatment plan. Hope this helps. Good luck.

If your hair grows back after Telogen Effluvium it should not regrow with a different color. You may be seeing something else.  You should see a doctor for an examination.

Telogen Effluvium cycles and normal hair returns after the cycle is complete. Your hair may be developing white hair which is changing its character that is common in aging. If you are thinning, scalp micropigmentation may have value for you (see below)
