Slightly off topic but what's the difference between Texlaxing and under-processing?
I used texlaxing as a bridge when I was transitioning from relaxed to natural/sisterlocks
.
Correct me if I'm wrong... my explanation of texlaxing is using a relaxer to reduce the curl in the hair. This is normally done by reducing the application time, using a milder relaxer, adding an oil or conditioner to the relaxer, applying a barrier to the hair prior to application or a combination of the above.
From my understanding people texlax for better managability, less frizz, to gain more volume or as a happy medium between natural and relaxed. The results are somewhat uniform.
Underprocessed hair is when a relaxer has not 'taken' or achieved the desired results. Underprocessing can be all over the head, isolated to one area or within a strand. I find it normally happens due to the incorrect strength relaxer, application method or not smoothing enough. Overtime you may experience breakage because of differing textures and a feeling of rough hair.
They are similar but underprocessed hair is normally accidental. Texlaxed hair is intended.
I tried to be texlaxed but could not tell the difference when my new growth came through so I relaxed straighter!
I was natural for 2.5 years and recently relaxed my virgin hair. However, it's came out underprocessed because I didn't leave the relaxer in for long enough at all
