Nutrition supplements for hair and nails?

[orangejuice]

I used to live in a humid place and my hair was really healthy and long. and recently i moved to a place that has really dry air so my hair started drying up and breaking. i noticed my nails are brittle too. so i want hair and nail supplements but i don't know which brand to get. i went to the vitamin store and they had so many different kinds. My question is what brand do you think is the most trustworthy and has the best quality. Please list the price or where i can purchase it. If you have any tips or advice on growing hair that would be helpful too. Thanks for taking the time to answer my question
