Since you have straightened your hair alot, your hair has changed to a straighter texture. You should try not straightening it so much and let it grow out, it will go back to its curly texture eventually.How long do i have to use a shampoo for it to do what it claims it does?
try either perming it, or use a curling iron on it. That may help bring the curl back.
