OGX Brazilian Keratin Therapy Shampoo for Shiny Hair, Sulfate-Free, with Coconut Oil and Avocado Oil, 13 Fl Oz


My Hair Stays Straight & Tamed Without Products – Love It!


I have extremely thick hair down to my collar. Before I used this, my hair was wavy and very unruly. But after using this my hair is extremely straight and stays combed back without any product. 10/10 would recommend.


Shampoo Basics & Tips


How This Shampoo Works for Thick, Unruly Hair


The reviewer mentions achieving straightened hair without styling products. This occurs through specific smoothing agents like keratin proteins that penetrate hair shafts to reduce frizz. Thick hair often requires hydrating ingredients (e.g., argan oil) to soften coarse strands while maintaining volume control.


Why Hair Stays Combable Without Product


Cuticle-smoothing formulas flatten hair's outer layer, reducing static and friction. Ingredients like amino acids help maintain this effect through multiple washes. For collar-length hair, this creates natural weight distribution that keeps styles intact.


Managing Different Hair Types


Thick hair (50-120μm strands) needs stronger surfactants than fine hair. Look for sulfate-free cleansers with coconut-derived bases that remove buildup without stripping natural oils. Wavy textures benefit from pH-balanced formulas (4.5-5.5) to prevent curl disruption.


Common Shampoo Concerns Addressed


Users often ask: "Will straightening shampoos damage hair?" Quality versions use heat-free smoothing through chemical bonds rather than harsh alcohols. For color-treated hair, ensure formulas contain UV filters and color-lock technology.


Enhancing Results Between Washes


Pair with cold water rinses to seal cuticles. Sleep on silk pillowcases to maintain straightness. Avoid over-brushing – wide-tooth combs preserve smoothness better than boar bristle brushes for thick hair types.
