The hydroxide relaxer
that does not require the application of a protective base is a no-base
relaxer. No-base creams have a lower concentration of lye and may be
applied directly to the hair roots without requiring the protective layer like
use of petroleum jelly onto the scalp. In addition, even when using no- base relaxers, stylists still put an
additional protectant around the ears and hairline to prevent irritation to the
skin. Nevertheless, they still contain chemicals in the first place.
