Redken Acidic Grow Conditioner 33.8 fl oz — Lightweight Densifying Scalp & Hair Conditioner for Thicker-Looking Hair

Redken Acidic Grow Full System Scalp and Hair Conditioner is a lightweight, densifying conditioner that hydrates the scalp and adds thicker-looking fullness to thin or flat hair.

This conditioners sits at the center of Redken’s Acidic Grow Full System: a four-step routine formulated to support scalp hydration and visibly fuller hair when used with the matching shampoo, serum, and instant densifying spray. It blends a 7% Densifying Complex with scalp-friendly ingredients including azelaic acid, giving thin, thinning, or flat hair an instant conditioning and volumizing finish while remaining safe for color-treated hair.

How does this conditioner add body without weighing hair down?

The formula is designed to be lightweight yet effective: it deposits moisture where hair and scalp need it most while avoiding heavy residues that flatten fine hair. The result is conditioned strands with lift and a soft, full feel.

• 7% Densifying Complex targets strand thickness and density for fuller look
• Light, non-greasy texture rinses clean to preserve volume
• Instant conditioning effect that improves manageability without buildup

Will this help my scalp feel balanced and comfortable?

Yes — the conditioner contains azelaic-acid–containing components that support a balanced scalp environment while delivering light moisture. It’s formulated to rebalance scalp hydration so skin doesn’t feel overly tight nor greasy after use.

• Gentle hydration targets dry areas without excess oiliness
• Scalp-conditioning ingredients help keep skin feeling comfortable
• Suitable for regular use as part of the full Acidic Grow system

How should I use this product to get the best results?

For optimal performance, use the conditioner after the Acidic Grow Full System Shampoo, then follow with the Redken Scalp & Hair Serum and Instant Densifying Spray. Work a small amount through mid-lengths to ends, focusing on areas where hair is thin or flat, and rinse thoroughly.

• Apply to wet, shampooed hair concentrating on mid-lengths and ends
• Leave in briefly to let the Densifying Complex penetrate, then rinse
• Use with the full four-step Acidic Grow system for best visible results

Is this safe for color-treated or chemically treated hair?

The conditioner is formulated to be safe for color-treated hair while delivering hydration and volumizing effects. It conditions without stripping color and is gentle enough for regular use when combined with appropriate color-care routines.

• Color-safe formula maintains color integrity during routine use
• Non-damaging, lightweight conditioning supports styled and treated hair
• Pairs with professional Redken color-care practices
