Reading through the thread I was wondering when actual facts were going to emerge
. Ladies lets not assume the chemicals are the same, it is very important we educate ourselves on the differences in chemicals otherwise you will mess up your hair. Texturizers and Relaxers have very different active ingredients. Intended for very different functions.
(Info taken from another site) Sodium Hydroxide Hair Relaxer:
Sodium hydroxide is used
to remove unwanted curl from the hair. The difference between the
strengths depends upon the percentage of active ingredients. This relaxer
is alkaline in pH, which forces the cuticle to open so that the relaxer
can penetrate into the cortex layer of the hair. Once there, the sodium
hydroxide breaks the disulfide bond. When this happens, the hair will
smooth out to a straightened form due to the weight of the crème, the
pressure of smoothing, or in extremely curly hair, the gentle combing of
the hair.Ammonium Thioglycolate Hair Straightening. (Nicknamed "Thio relaxer")
Thioglycolate is used to straighten as well as curl the hair.
Therefore, the process is reversible. The same chemical reaction that
puts curl in the hair during the permanent waving procedure, takes curl
out of hair in chemical straightening. Thioglycolate is the main
chemical ingredient in Japanese Thermal Reconditioning/TR systems, and
permanent wave products. This process is much less drastic in its
action than the sodium hydroxide. It acts a little differently by
softening and relaxing overly curly hair through changes to the hair's
cystine linkage. And of course,
a fragrance is added, since the “thio” compounds all possess a rotten egg
or skunk-like odor.
Thio works on the same formulation principles as
Thioglycolate permanent waves. Thio relaxers are also considered to be
less damaging, yet still require a neutralization step. Since Thio
relaxers are considered much milder, the risk of hair damage is also
reduced by comparison to the sodium hydroxide.
Today thioglycolate is the # one choice with stylists.NEVER perm hair that has been treated with a sodium hydroxide relaxer.
This also includes calcium hydroxide as well as potassium based
relaxers. Even if they say "No Lye" the rule still applies.
Sodium hydroxide and Thio chemistries are not compatible.
Hair that has been chemically relaxed with any of these can not be
permed until ALL the hair that was treated with the relaxer has been
cut off, as it would be destroyed anyway, by perming over it.Thio (Ammonium Thioglycolate, the reducing agent in perm lotion) breaks
bonds in the hair differently than sodium hydroxide, and as a result,
one can not be used over the other.
If however, the hair was treated with a thio relaxer, that is the same
chemistry as a perm, and the hair can be permed again, over that, as
long as its condition dictates that it all right to do so.Fin
So generally speaking from a natural vs chemically altered perspective. Relaxing/texturizing would be the same thing as they both dramatically change the hair from its natural state. However the chemicals differ greatly in the way they affect the hair. So basically, what ever chemical treatment you choose to apply to your hair, be prepared to make a long-term commitment because alternating between the two is a recipe for damaged hair or no hair at all.
