Female with massive hair loss

I am a 28 year old single female. 3 years ago I started losing a lot of hair, my my estimate almost 70% of my hair. Now I have started multivitamin for the past 3 months and the hair stopped falling out and some regrowth has happened.  Shall I get PRP added to what I am doing?  

If you have seen value from taking multivitamins, then you may have a Vitamin deficiency and you should get the various blood tests to document which type of problem you have rather than treat it blindly. Doing PRP is just grasping for straws and does not make sense in the absence of a diagnosis and you may be wasting your money or worse, losing hair while you fail to get the right treatment for your ‘unknown’ condition.
