CHI Enviro American Smoothing Treatment (for Highlighted, Porous, and Fine Hair) is a professional-grade, salon-exclusive trichological therapy designed to restructure and align compromised hair fibers. From a dermatological and trichological perspective, highlighted and fine hair structures exhibit high porosity, protein depletion, and a vulnerable cuticle layer due to prior chemical processing (such as bleaching or oxidation).
Key Trichological Benefits & Clinical Value
1. Structural Repair of High-Porosity Hair Shafts
Chemical highlights strip the hair's natural lipid barrier and deplete internal keratin, causing a highly porous cortex that absorbs moisture unevenly, resulting in frizz. This treatment infuses bioavailable proteins directly into these microscopic voids, reinforcing the hair's structural integrity and restoring hydrophobic balance.
2. Elimination of Frizz without Loss of Natural Volume
Fine hair is highly susceptible to limpness and mechanical breakage when weighed down by heavy, synthetic polymers. This lightweight, targeted formula smooths the outer cuticle scales while preserving the natural body and elasticity of fine hair fibers, significantly reducing daily detangling friction.
3. Protection against Thermal and Mechanical Stress
Highlighted hair is highly vulnerable to heat-induced protein denaturation during daily styling. By coating the hair fibers with a resilient, heat-activated protective matrix, the treatment minimizes future moisture loss and cuticle cracking from blow dryers and flat irons.
Ingredients & Mechanism of Action
The Pearl & Silk Complex
The formulation utilizes a biological delivery system engineered to mimic the natural composition of human hair proteins:
Hydrolyzed Silk: Composed of 17 of the 19 amino acids present in human hair, hydrolyzed silk proteins possess an ultra-low molecular weight. This allows them to penetrate deeply past the cuticle into the cortex, bonding with damaged keratin chains to increase tensile strength.
Pearl Powder Extract: Rich in natural marine minerals, calcium, and amino acids, pearl powder acts as a natural UV-absorber and cuticle-refining agent, smoothing the hair surface to optimize natural light reflection.
Glycolic Acid & Amino Acid Blend: Instead of breaking sulfur-to-sulfur (disulfide) bonds to force a permanent structural change, this active blend temporarily rearranges the keratin chains under controlled heat. The acidic pH safely smooths the hair without causing chemical damage or cuticle swelling.
Paraben-Free & Formaldehyde-Free Preservation: Formulated to eliminate exposure to gaseous formaldehyde, a known respiratory and ocular irritant, ensuring safe application for both the stylist and client.
Professional Application Instructions & Safety Precautions
Step-by-Step Clinical Application Guide
Due to the precise temperature and chemical controls required, this treatment should be administered by a certified professional stylist:
Purification: Wash the hair thoroughly with CHI Enviro Purity Shampoo to strip away accumulated sebum, styling polymers, and mineral deposits, leaving the cuticles receptive to the treatment.
Drying: Rough-dry the hair to approximately 80% using a professional hair dryer on a medium heat setting.
Application: Section the hair into clean quadrants. Apply CHI Enviro Smoothing Treatment systematically in small, 1/4-inch sub-sections using an application brush, starting 1/4-inch away from the scalp to avoid direct follicular contact.
Processing: Allow the treatment to process at room temperature for 45 to 60 minutes, depending on the hair's density and porosity level. Do not apply artificial heat during this phase.
Drying & Thermal Activation: Blow-dry the hair completely smooth on a medium heat setting.
Flat Ironing: Using a high-quality ceramic or titanium flat iron, iron the hair in thin sections.
Important Thermal Limit: For highlighted and fine hair, the iron temperature must be strictly maintained between 180°C and 190°C (350°F and 375°F). Pass the iron over each section 4 to 6 times to thermally seal the amino acids without causing thermal damage.
Crucial Safety Precautions
Contraindications: Avoid application if the scalp presents open lesions, active dermatitis, psoriasis, or severe chemical burns from prior bleaching.
Ocular Contact: In case of accidental contact with the eyes, rinse immediately and thoroughly with sterile saline or lukewarm water for at least 15 minutes and seek medical advice if irritation persists.
Ventilation: Although formaldehyde-free, ensure the salon space is well-ventilated during the blow-drying and flat-ironing phases to minimize inhalation of concentrated water vapor and aerosolized emollients.
Post-Treatment Care: Do not wash, wet, tie back, or clip the hair for 48 hours following application to ensure the protein restructuring process fully stabilizes. Use only sulfate-free and paraben-free maintenance shampoos.
