Hi I'm A 24yrs Male Residing In USA. From The

Hi I'm a 24yrs male residing in USA. From the past few yrs i have been experiencing hair loss. Sometimes less sometimes more. For this,i started using the Jamaican black castor oil but i don't think it helped me in the hair fall but i could say it helped in darkening of hair and made it a little thicker. I masturbate alot. Sometimes 4 times a day sometimes 6 but yesterday i have stopped it completely . I workout regularly. Drink protein shakes. Should i go for the biotin supplements(5000mcg)? Also I'm using Nioxin system 2 shampoo.
