Hi, Welcome to Healthcaremagic!
is a 'B' vitamin group vitamin (also known as vitamin H), which is used in high doses of 5-10 mg daily for hair loss; it is totally safe but will work for hair loss if hair loss WAS due to it's deficiency. As you are anaemic, consult a general physician as advised for finding a cause of your low Hb-- it will be much more fruitful to treat cause rather than taking a shotgun iron tablet or biotin tablet for hair loss. Minoxidil
2% is also useful in female pattern baldness-- so you may consider consultation with dermatologist
also. Good luck.
