Keratin treatment

The package contains a shampoo and keratin and a mask. Instructions for use are easy. I myself have damaged hair due to bleaching, etc. Now my hair is a bit shiny and a bit straight, but feels soft. I don't have thick hair, but after one use, I still have a lot left over for a second or even third treatment. Product doesn't smell bad. It only smells a bit strong when you blow dry. After washing, the smell is already gone. I wonder what it will look like after a few washes.
