curlyauburn, I believe that they do come back....the promise is that it's like a relaxer but without the chemicals that make your hair permanently straight....
my mom's hair went straight because it's wavy/curly...mine is 3B curly so it probably won't go straight....
I'm washing it tomorrow and I'll try this and let you know...If it turns out good I'll post pics...
Was 3b then I did a soft relaxer and I think I'm now a 3a
