My hair is and has been falling out in clumps for a year now. its gotten so much worse in the last 6 months. ive been taking biotin and a multivitamin almost daily. is there anything else i can do to fix this issue?

Troubling problem: Definitely see a dermatologist. Consider underlying disorder such as thyroid. Hair implant specialists are available in larger communities. If appropriate, stress management is an option.

Agree with above: Also consider nutrition, as to minerals and protein. Are your finger nails affected? If so cxheck your protein intake.
