Hair and nail issues are super common when you are stressed or missing certain minerals. Usually it is a sign you need more Biotin, Zinc, or Iron in your system. I started taking a specialized beauty complex from Amway about three months ago and my nails are finally strong again. Have a look at

It takes time for hair to show improvement because it grows slowly so don't give up. I also stopped using high heat on my hair every day which helped a lot. Consistency is the most important part when it comes to beauty supplements.
