Abnormal Hair Growth and Hair Loss. Do?

I am facing Hair Loss on crown and front-top area from past 1.5 years,Currently the hair fall is reduced but there is no or very slow growth of hairs. I am currently taking Biotin tab(10mg). I also have longer hairs over my front torso and legs(~1in). Also on my shoulders and my upper back(near shoulders), some hairs have grown much longer than others (apx.5x long & ~1inch) in the past 1 year.Could this be Hormonal? Or due to deficiency of something. What should I do? Previously during my 1.5 years, I was recommended MorF3% which I used for around 1 month(¾bottle) in the starting and it didn't had much impact and I don't want to use it because it have to be used for rest of life. I also started eating eggs to increase protein diet. This resulted in fewer hair fall. I have dandruff and sometimes I flick out dandruff flakes by scratching scalp.I also have felt a few bumps(like pimple)over my scalp(rare). I use selsun shampoo for dandruff and with 2-3 washes it clears out for a few weeks.
