I just got this question from Tess and thought I should answer it in a blog post incase anyone else is interested in the answer.
Texlaxing is under processing the hair on purpose. It is done using a relaxer. This can be done by leaving the relaxer on your hair for a short time before rinsing it off, by adding an oil to the relaxer so as to weaken it, by adding just a little of the activator to the relaxer base (as opposed to adding the entire thing to the base) or by skipping the smoothing step. The idea is to lightly loosen the curl pattern resulting in a wavy texture.
Texlaxing is great for those looking to retain some degree of thickness in their hair, moreso, those with fine hair, or those who still want to relax their hair but find that for whatever reason, their hair is thinning.
Texlaxing is also the healthier option as opposed to relaxing hair straight. Don’t get me wrong, all chemical treatments damage hair to some extent but texlaxing is milder.
This is all I can come up with for now. Got any more questions? Please feel free to ask and I’ll try my best to answer 🙂
