I wouldn't suggest a perm. I got one to do the opposite to my hair and it took me 3 years to grow out the damage. Perms look pod the first couple times you do them but the damage accumulates and starts to look awful. So I jut suggest putting your hair in braids after wetting it, then taking it out the next morning and spritzing with hair spray
Yea it's called a digital perm, either way is damaging in my opinon. If you put heat in your hair all the time then it will ruin it, you can risk ruining your hair with a perm because of the chemicals but at least with a perm you don't have to maintain the waves with heat so much because it will already be wavy.
I have curly hair and I had a relaxer done, it ruined my hair. It would be better to just curl your hair like that using heat protector. Or just make sure you know exactly what you're doing when you take care of your hair
