I am 44, my hair used to be thick and grow quickly, really quick and thick. I am devastated as my hair is now thinner and hardly grows.. I used to use semi permanent dye now I use permanent dye, ammonia free and although I do straighten my hair I used to staraughten before it started to thin and now grow. My nail are terrible, they split and flake, I used to have strong nails.. is this all part of getting older or not? I don't smoke or drink and exercise, eat fairly healthy. Oh and to boot my gums are receding. I feel I need some help..any advice please
