Shock hair loss solution. Medication.

I went from having thin silky hair all life to dry rough dandruff filled hair in May. Mid May, it started falling out. I easily lost a fistful bunch every time I paid attention. I am now concerned because it is falling out in clumps, throughout the day, and it is everywhere without even trying to comb. Knot-free hair too, if tried to comb (even with a finger), results in clusters falling out at once. It is very very extreme. I am guessing it is Telogen effluvium considering my 10 day water fast experience in late april and continuous alternate day fasts ever since, that have helped me shed 10kgs (61kg-51kg) in a short period of time. Please clarify whether it is this or Female pattern baldness. I am losing hair at an alarmingly fast rate with visible baldness, and so I would kindly request an urgent supplement to save my hair. I'm willing to make a healthy diet lifestyle change asap, but until that shows on my hair, I'm afraid it'll be too late. Please suggest immediate medication.
