Is the Keratin Hair Treatment by Coppola a good idea for me?

I recently went to an Ulta salon to have my hair done, and the stylist said that the new Keratin hair treatment would be good for my type of hair. I have very fine curly hair that is noticeably thin in some parts and she said it would make my hair looks thicker. Is this true or will it look worse?Is the Keratin Hair Treatment by Coppola a good idea for me?
the treatment could be beneficial to your hair routine. it smooths out the hair and gets rid of any frizz and uncontrollable curls. but since you state that your hair is thin, my suggestion would be to keep it that way because then your hair could turn out flat. no, the keratin treatment by no means does not make hair any thicker, it will make the hair stronger though, the protein will make the hair a lot less breakable. however if you want to try the product, it is not damaging to the hair and it only last for 6 months, by then the treatment would be gone and your hair will be back in it's natural state.
