diagnose the problem. and then treat it.
1)inherit baldness (if ur father or mamoos are bald)= no solution, adapt bald styling, don't let it effect your life.(its some testosterone imbalance type problem, side effect of fixing it is dangerous and can cause permanent damage)
2)head fungus(itchy head , dandruff mixed with oil, other danny etc)= Use batonil lotion mixed with your Favorite oil(just apply no massage), wash your head daily with good anti-dandruff shampoo , use stieprox shampoo 3 times a week. continue for 3 months even if it seems its treated.
3) pattern baldness (back or front only) = use HAIR,NAILS,SKIN supplements(vitamins) recommended by doctor. massage with oil 3 time a week. get protean hair treatment from hair saloons(once a month). exercise daily. (its due to blockage in blood flow by fat).
4)Testosterone imbalance (non-inherit)= again don't take treatment for it. search for finasteride side effect. it causes prostate growth and cancer etc
always ask doctor before using any medicen. and once your hair starts falling u can only slow it down. after 35 years of age every men hair density starts decreasing. & ... REMEMBER !!! GETTING DEPRESS DUE TO HAIR FALL , SPEEDS UP THE HAIR FALL.
