ColorProof Biorepair Thicken Conditioner 8.5 fl oz — Scalp-Exfoliating, Color-Safe for Fine & Thinning Hair

If you have fine or thinning hair that’s also color-treated, this conditioner combines gentle exfoliation, peptide nourishment, and plant-derived actives to refresh the scalp and create the appearance of thicker, more resilient strands. It’s formulated to protect color vibrancy while addressing the scalp environment—one of the key areas that affects hair density and perceived volume.

How does this conditioner improve scalp health without harming color?

The formula uses an Advanced Color Last System to shield dye molecules from environmental fade while Alpha Hydroxy Acid (AHA) gently exfoliates the scalp. Together they clear debris that can block follicles yet preserve the pigments and shine of treated hair.

• Advanced Color Last System defends against sun and pollution-related fading.
• AHA removes dead skin cells, oil, and product buildup to free follicles.
• Sulfate-free base and clean formulation maintain color integrity.

Which ingredients support thicker-looking hair and how do they work?

Biotin and copper peptides help nourish the scalp and support follicle health, while the Phyto-CP Complex—grape stem cells—supports a balanced scalp ecosystem. A blend of phytonutrients and essential oils revitalizes the scalp and hair for improved body and texture.

• Biotin and copper peptides target scalp nourishment and follicle support.
• Phyto-CP Complex maintains scalp balance and resilience.
• Pea sprout, ginkgo, tea tree, peppermint, and rosemary oils refresh and invigorate.

How should I use it for best thickening results?

Apply from scalp to ends after shampooing, then gently massage with a scalp brush to enhance exfoliation and circulation. Rinse and follow with the Biorepair Thicken Scalp Serum to complete the regimen for optimal fullness and scalp care.

• Use on damp hair after your cleanser—leave for a minute or two for active ingredients to work.
• Pair with a scalp massager brush to lift buildup and stimulate circulation.
• Follow with the matching scalp serum to support continued scalp health and thicker-looking hair.

Is this product clean, safe, and suitable for sensitive scalps?

The conditioner is formulated without parabens, is 100% vegan, cruelty-free, and free from harmful additives and sulfates. While it’s designed for thinning and color-treated hair, those with very sensitive scalps should patch-test because of active exfoliating ingredients like AHA and essential oils.

• Paraben-free, sulfate-free, and free from common harsh additives.
• Vegan and cruelty-free; formulated for thinning, color-treated hair types.
• Patch-test recommended for highly reactive or compromised scalps.

Who is this for: ColorProof Biorepair Thicken Conditioner is intended for people with fine, thinning, or density-challenged hair that is color-treated and needs a lightweight formula to boost volume without stripping dye. It’s a good choice if you want a clean, salon-grade product that pairs with a scalp brush and targeted serum to create fuller-looking hair while preserving color longevity.
