Redken Acidic Grow Full System Instant Densifying Spray 200mL

Is this product for you?
• Fine, thin or flat hair needing instant fullness
• Hair that struggles to hold body and volume
• Hair prone to breakage from brushing
• Regularly blow-dry or heat style your hair
• Want thicker-looking hair without heaviness or crunch

Redken Acidic Grow Full System Instant Densifying Spray is a lightweight leave-in treatment designed to instantly make fine, thin or flat hair look fuller, thicker and more dense. Formulated with Redken’s 5% Densifying Complex, it adds body to the hair while providing heat protection up to 230°C — making it the perfect final step before blow-drying and styling.

When used as part of the complete Acidic Grow Full System, it provides the appearance of fullness equivalent to +5,000 hair fibres.*

Why we love it:
✔️ Instant Density – Gives fine hair an immediate fuller, thicker-looking appearance
✔️ Lightweight Volume – Adds body without weighing down fine or flat hair
✔️ Heat Protection – Protects against heat styling up to 230°C
✔️ 2x Stronger Hair – Supports stronger strands when used as part of the complete system
✔️ 2x Less Breakage – Helps reduce breakage caused by brushing as part of the system
✔️ 5% Densifying Complex – Uses densifying polymers to create visible fullness
✔️ Colour-Friendly – Suitable for colour-treated hair

Perfect Pair:
For maximum fullness, use as the final step in the Redken Acidic Grow Full System. Start with Densifying Shampoo & Conditioner, apply the Scalp & Hair Serum to your roots, then finish with Instant Densifying Spray through your lengths before styling.

Who’s it for:
Fine & Thin Hair – Creates instant visible density and body
Flat Hair – Adds fullness when your hair tends to fall flat
Breakage-Prone Hair – Works within the complete system to help strengthen fragile strands
Heat-Styled Hair – Protects up to 230°C while adding fullness
Colour-Treated Hair – Suitable for coloured hair without creating unnecessary weight

How to use:

1. Apply to damp hair before styling
2. Hold approximately 15cm away from the hair
3. Spray evenly through the mid-lengths and ends
4. Comb through to distribute
5. Blow-dry and style as desired for maximum fullness

What’s inside:
Powered by Redken’s 5% Densifying Complex, including densifying polymers that help give each strand a fuller, thicker-looking appearance. The Acidic Grow Full technology also features Azelaic Acid, Caffeine and Prebiotics within the complete system to support scalp balance, hydration and stronger-looking hair.

Finished with a warm citrus fragrance featuring Italian Lemon, Neroli and Vanilla Bean.

Tip:
If your hair is fine, don’t assume more product = more volume. Light, even application is the secret. Spray through damp hair, comb it through and let your blow-dry do the rest. For the biggest difference in fullness, use all four steps of the Acidic Grow Full System together.
