Redken Acidic Grow Full System Scalp & Hair Conditioner — 33.8 fl oz, Lightweight Azelaic Acid Densifying Formula

Redken Acidic Grow Full System Conditioner is a lightweight, scalp-focused conditioner that hydrates and helps create the appearance of fuller, thicker-looking hair while supporting a balanced scalp.

This salon-grade conditioner is formulated with a 7% Densifying Complex and azelaic acid to address the needs of thin, flat, or thinning hair without weighing strands down. Designed to pair with the rest of the Acidic Grow Full System, the formula targets scalp moisture balance and surface conditioning so hair looks fuller, feels softer, and is ready for styling. It’s safe for color-treated hair and created for daily use.

How does this conditioner add volume without heaviness?

The lightweight base and specific densifying actives condition strands without coating them in heavy silicones, so hair maintains lift at the root. It deposits just enough moisture to smooth and detangle while preserving body and natural movement.

• 7% Densifying Complex designed for fuller-looking strands
• Low-residue conditioning to avoid weighing hair down
• Instant detangling for easier styling and lift

What does it do for the scalp and why is that important?

The formula helps rebalance scalp moisture and soothe the surface, creating a healthier foundation for hair to look its best. A well-conditioned scalp supports smoother, shinier strands and can help hair appear denser overall.

• Azelaic acid to help maintain a balanced scalp environment
• Light hydration that won’t leave the scalp oily
• Made to work alongside the Acidic Grow Full System for full benefits

How should I use this product in my routine?

Apply after shampooing with the matching Acidic Grow shampoo. Work a small amount through mid-lengths to ends, and gently massage the scalp to distribute nourishment, then rinse thoroughly for optimal texture and hydration.

• Best used following Acidic Grow Full System shampoo
• Use daily or as needed for detangling and light conditioning
• Follow with styling products or the Acidic Grow Serum and Spray for added density effects

Will it work on color-treated or fine hair?

Yes — the conditioner is formulated to be safe on color-treated hair and gentle enough for fine textures. It is designed to deliver conditioning benefits while preserving color and preventing limpness.

• Color-safe formulation for salon-treated hair
• Non-greasy finish suits fine and thin hair types
• Compatible with additional Redken styling and densifying products

Who is this for: Redken Acidic Grow Full System Conditioner is intended for people with thin, flat, or thinning hair who want a lightweight conditioner that supports a hydrated scalp and creates a thicker-looking finish. It’s also a good match for those using GLP-1 medications who have noticed changes in hair density and for anyone seeking a color-safe, salon-quality conditioner to use daily or alongside Redken’s full Acidic Grow regimen.
