The answer is No.

-Because of the way the loc extension is created. My loc extensions are constructed in a very abstract way—-wrappping, braiding, and knotting. The ending result is a head full of natural looking locs. Hair is not added later and no special treatment required.

I’ve started many loc extensions with client who have permed hair. The fact is: the loc extension will be added on top of the hair; so the kinky hair growing out the scalp will only be shown as it grows out.
