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!I heard Keratin hair treatment is good for your hair, but how do you prepare the treatment yourself?
All ';Keratin'; is is protein.


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


Hope this helps.
