How it works: The active ingredient is Guanidine Hydroxide, a mix of calcium
hydroxide cream and guanidine carbonate, or ammonium thioglycolate. These are
called no-lye, but they are still lye. These chemicals, like sodium
hydroxide, break down the hydrogen and sulfide bonds that give the hair its
shape rearranging the hair bonds.

A no-lye relaxer is an option for people whose scalps are sensitive or who use a
permanent coloring agent, although it is not recommended by many experts. This
formulation is best on hair that just needs its curl loosened a bit.

Pros:
It allows you to color and relax your hair, but never do both at the same time.
Space these processes at least two weeks apart, or be sure to consult a trained
cosmetologist before coloring your hair after a relaxer. Only a well-trained
and experienced professional can handle the dual processes well, and only women
with well-conditioned and coarse hair should opt for both.

Cons: This type of
relaxer deposits additional calcium on the hair, making it more prone to
dryness and breakage. A consistent moisturizing regimen is a must with relaxed
hair be it with no-lye or lye based relaxers. No-lye relaxers will not
completely straighten super-tight hair, which leaves the shaft more porous and
susceptible to damage. For this reason, many experts do not use this product.
Like lye relaxers, no-lye relaxers can cause severe scalp and hair damage. This
information does not mean that you should absolutely not apply No-lye Relaxer.
It’s still can be used if applied incorrectly. Always seek for professional
services.
