How Apple Cider Vinegar Helps Hair Loss

I am 32 years old and from India and had a very thick hair before i came to US 3 years back. Eversince i have come here i started having terrible hair loss. I never had any ailment, stress etc. I have seen many of my male friends going nearly bald here. Is it in the water that we drink or shower. The right side of my scalp got more affected. Cutting the story short, i have started taking ACV for about a month now, 2 tablespoons in a glass of water taken twice a day. I also use diluted ACV as a final rinse when i wash my hair every weekend. I can say this - my hair has started looking much healthier. I cannot say if it has reduced my hair loss, i hope it does. I also started taking cold shower wash instead of hot water.
