ColorProof Biorepair Thicken Scalp & Follicle Serum 3.4 oz — Lightweight, Color-Safe Scalp Exfoliant for Fuller-Looking Hair

This lightweight serum targets thinning, color-treated hair with a blend of biotin, copper peptides, AHA exfoliants and plant-derived actives designed to clear build-up, energize follicles and help hair appear denser. Formulated for regular use on damp or dry hair, it pairs with ColorProof Biorepair Thicken Shampoo and Conditioner to maintain scalp balance and color longevity. The fresh lime, eucalyptus, mint leaf and rosemary scent refreshes the routine without weighing hair down.

How does this serum help make hair look thicker?

The formula combines exfoliating AHAs with strengthening nutrients so strands can sit fuller at the root. By removing excess oil, dead skin and residue that can compact around follicles, the product helps hair emerge without obstruction while peptides support resilient-looking shafts.

• AHA gently exfoliates scalp surface and clears build-up.
• Biotin and copper peptides nourish the hair base and follicle area.
• Phyto-CP grape stem cells support scalp vitality for healthier-looking hair.
• Lightweight texture avoids weighing color-treated strands down.

Is this safe for color-treated hair and does it protect color?

Yes — the serum is built on ColorProof’s Advanced Color Last System to reduce color fade from environmental stressors. Ingredients were selected to be color-conscious, keeping strands vibrant while improving scalp condition.

• Advanced Color Last System shields hair from UV and pollution effects.
• No heavy silicones that mask color or create build-up.
• Cleansing AHA helps remove residue that can dull dyed hair.

How do you use the Biorepair Thicken scalp serum for best results?

Apply a few drops twice daily directly to the scalp using the dropper, then massage with fingertips to distribute. Use on damp or dry hair and follow with styling as usual; consistency yields the most noticeable change in scalp feel and hair density appearance.

• Apply 1–2 drops per section, targeting thinning areas twice daily.
• Massage for 30–60 seconds to activate circulation and distribute formula.
• Pair with Biorepair Thicken Shampoo and Conditioner for a complete routine.

What key ingredients are inside and what do they do?

The serum blends exfoliants, peptides and phytonutrients to address scalp environment and hair strength without harshness. Essential oils provide a fresh scent while delivering antioxidant and calming benefits to the scalp surface.

• AHA: exfoliates away dead skin and product build-up.
• Biotin & copper peptides: support stronger-looking hair emerging from the follicle.
• Phyto-CP (grape stem cells): helps maintain a balanced scalp ecosystem.
• Peppermint, tea tree, rosemary oils and pea sprout deliver nutrient support and a refreshing scent.

Who is this for: This serum is designed for people with thinning or fine hair who color their hair and want a non-greasy, daily scalp treatment that supports fuller-looking results. It’s suitable for all hair types seeking to reduce surface build-up, protect color vibrancy, and add the appearance of density without heavy styling products. Ideal for anyone wanting a targeted, easy-to-use dropper serum to add to an existing color-care routine.
