## Overview

De Fabulous Cysteine Complex is a professional-grade, formaldehyde-free curl softening treatment that reduces curl volume by up to 70%, eliminates frizz, and strengthens hair with cysteine amino acids. Safe for all hair types including color-treated and chemically processed hair, it delivers smooth, manageable curls and long-lasting softness for up to 12 weeks.

## Description

Cysteine Complex works in synergy with hair’s existing proteins to restructure, soften, and release curls from hair. The healing capabilities of the Dendrobium Orchid absorb and eradicate free radicals. Cysteine is a compound already found in hair, and it makes up about 40% of hair’s natural protein composition. Cysteine Complex from the desertcart Series works to restore the proteins in hair that have been lost over time. Curl volume is reduced, leaving hair straighter and more manageable. The reduction of curl volume as a result of applying Cysteine Complex is up to 60% on ethnic, virgin, and coarse hair, and up to 70% on Caucasian hair.

Review: Tamaño perfecto - Recomendado
Review: Beware of hair breakage - Perhaps this was an old bottle, but my stylist followed instructions that I looked up on YouTube. The newest video I could find was from 10 years ago. The end result, major hair breakage and shedding! To add insult to injury, I am unable to return this product.
