What Is a No-Base Relaxer?

A no-base relaxer is a relaxer formula that includes a protective cream so that a protective base does not have to be applied to the scalp first. No-base relaxers also contain lower concentrations of lye, which means they are less likely to irritate the scalp.

The protective coating is typically made of petroleum jelly. Even when using no- base relaxers, stylists might apply an additional protectant around the ears and hairline to prevent irritation to the skin.

A relaxer is a chemical formula that relaxes tightly curled or wavy hair so that it falls straighter from the scalp. Some people apply relaxers to their own hair, while others visit a beauty salon for professional service.
