Can keratin therapy be used for kids about ten years old? Or its risky?

I know shampoo everyday is actually bad for you. What else?

How do I stop hair fall? Which food should I eat ? Which oil should I apply?

I always had the type 1 and 2A straight hair. And recently for a month I'm noticing my hair has become so wavy more like spring. Which is type 2C hair. I don't know what happened or how to get my straight hair back. Both my parents have straight 2A type hair. Please suggest any home remedy or suppliments or products that might help. (Not into permanent rebonding, keratin or chemical straightening)

I have a ton of gray hair. I used to be able to hide it by the way I parted my hair. Now it’s beyond that point. I’m keeping the gray for as long as I need to. My scalp isn’t healthy and it’s causing my hair to fall in the front for years. Hormones imbalances,low glutathione levels,oxidative stress, and chronic stress in general leads to early graying. It actually started in my teens,but I used to dye my hair blonde so it wasn’t noticeable. I need to get hormones under control once I am in my new home. This is me though. It is what it is.
