Tell me how to get straight hair. I am Asian and a little African American. My mom has curly hair and my dad has straight so I have a little of curly and mostly straight.

My hair is already straight, it's just that the front of my hair and my sides would get curly. Also, when I take showers, hours later, it would puff up. I need ways to help my hair get straight so I can let it grow.

What I can't do now:

Perms
Chemicals
Gel - I don't feel like doing it EVERY morning

My sister has a straighter so if you say I should use it I'll try too.
