I heard Keratin hair treatment is good for your hair, but how do you prepare the treatment yourself?

What ingredients to use? I have fine hair and I would like to strengthen it and give it more volume

Thanks!

All "Keratin" is is protein.

Go to Sally Beauty Supply and ask what conditions are "Keratin" based.

Hope this helps.
