My brother had male pattern baldness some where between strange 2 and 3. He's been using
vitamin tablets, trigaene shampoo and am-exildil hair spray fir around 6 months now. But haven't seen much effect yet. The hair fall has decrease but not much effect on the growth. I head people use onion juice for hair re growth. Is it effective is yes how should he use it and what should be the frequency. Also any other remedy or method he should try?
