I'd recommend switching to organic products for your shampoo and conditioner, and to look in to preventative medications like Finasteride and Minoxidil which has been proven to halt and even reverse hair loss. PRP would also be an option for you. Before starting any medications it is best to check with your physician.
Most probably you have a androgenetic type hairloss. I dont advice to use finasteride because ofpossible side effects and being underthe necessity of using that chemical for almost life long to stop hairloss.You may start to use minoxidil %5 to thicken the crown area and stop hairloss.You would better planning to have anexam at hair loss expert for hair restoration surgery when you felluncomfortable about hair styling or total loss of hair..
