ColorProof Biorepair Thicken Shampoo for Color-Treated Hair — 8.5 fl oz, Concentrated Thickening Cleanser with AHA & Biotin

ColorProof Biorepair Thicken Shampoo is a concentrated thickening cleanser designed to refresh scalp health and create thicker, fuller-looking color-treated hair.

This salon-grade shampoo targets fine, thinning strands while preserving color vibrancy. Formulated with exfoliating Alpha Hydroxy Acid (AHA), grape stem cell Phyto-CP Complex, biotin and copper peptides, it removes product build-up and nourishes the scalp to support visible fullness. The scent blends fresh lime, eucalyptus, mint leaf and rosemary for an invigorating wash. Use it as the first step in the Biorepair Thicken system alongside conditioner and scalp serum for best results.

How does this shampoo help hair that’s been color-treated?

The formula includes an Advanced Color Last System that protects dyed hair from environmental fading while cleansing gently. It removes residues that can weigh down color-treated strands without stripping pigments, helping color stay vibrant between salon visits.

• Color-safe surfactants that lift impurities without aggressive fading
• Antioxidant-rich ingredients to guard against environmental stressors
• Designed for use on chemically treated and highlighted hair

What ingredients support thicker, fuller-looking hair?

Key actives such as AHA exfoliate the scalp to clear dead skin and buildup that can block healthy emergence of hair. Biotin and copper peptides supply nutrient support that helps prevent follicle minimization, while pea sprout and ginkgo deliver phytonutrients to strengthen strands.

• AHA to help gently exfoliate and renew the scalp surface
• Biotin and copper peptides for scalp nourishment
• Phyto-CP Complex (grape stem cells) to preserve scalp balance

How should I use it for best results?

Apply to wet hair, lather, and gently massage the scalp—using a scalp brush can lift impurities and increase circulation. Rinse and follow with the Biorepair Thicken Conditioner and Thicken Scalp Serum to complete the three-step routine aimed at improved thickness appearance.

• Use 2–3 times weekly or as needed for buildup-prone hair
• Pair with the scalp brush to enhance exfoliation
• Follow with step 2 conditioner and step 3 scalp serum for system benefits

Will this change the texture or weight of my fine hair?

The concentrated formula is formulated to cleanse deeply without leaving heavy residues, helping fine strands feel lighter and appear fuller. Ingredients focus on lifting and strengthening rather than coating, so hair retains natural movement and body.

• Lightweight conditioning that avoids weighing down fine hair
• Removes oil and product build-up for improved volume
• Fragrance adds a fresh, clean finish without heaviness

Who is this for: ColorProof Biorepair Thicken Shampoo is made for anyone with fine, thinning or color-treated hair who wants a salon-quality cleanse that enhances scalp health and the appearance of fullness. It suits men and women looking to protect hair color while removing build-up that undermines volume, and works best as part of the Biorepair Thicken three-step regimen for ongoing scalp and strand support.
