Can Samy hair products make my hair grow thick and healthy that got damaged due to weather change?

I live in South Carolina and I have recently moved to this new city. However, I have been facing excessive hair fall lately, and I assume that it has been due to the weather change here. Nonetheless, I want to know from some hair expert whether I should Samy hair products could make my hair grow thick and healthy again. I have never used any chemical on my hair, and I had long hair until recently, when I used to live with my family in Redmond. I have also started taking vitamin B supplements for hair growth, but for the shampoo, I would like to know from some hair expert whether it is a good option to try! Please suggest! Thanks.
