Should I get a keratin treatment to keep my hair curly or straight?

My friend recently got a keratin treatment and her hair looks great! I was thinking about getting one and then talked my self out of it, because I didn't want my curls ruined. I am now debating whether or not I want to try and get the keratin treatment to keep my hair curly... I really like my hair straight but I only like my curls how they are in the shower. After they dry they shrink up and get frizzy! HELP!

Don't get a keratin treatment! They completely ruined my hair with damage. When I finally decided to go natural, I had to cut off 8 inches of fried hair. There are much healthier ways to stretch your curls. Bantu knots, twist outs, braid outs, roller sets, techniques with gel, etc. 
your hair is curly and you haven't hair Straight. the keratin nourish your hair but they will not be any more as before or a moment will return as before !!The only thing which I can to tell you it is looks at videos for your hair
