Yes, you can start to lock your hair with a perm or texturized hair.
The technique that works best is Sisterlocks. With Sisterlocks the
natural hair is locked, and the relaxed hair is unlocked. You can style
your relaxed hair as normal, and as your natural hair grows out, trim
off the relaxed hair. To learn more about Sisterlocks visit the
