Redken Acidic Growth Full System Instant Densifying Spray for Thin Hair, Strengthens & Thickens 190ml

Redken Acidic Grow Full System Instant Densifying Spray is a lightweight leave-in spray designed to give thin, flat hair a fuller, thicker-looking finish. Formulated with azelaic acid, caffeine and a 5% densifying complex, it works to support a balanced-feeling scalp while coating each strand for instant body and lift. The fine mist feels weightless on the hair, helping to add volume from root to tip without stiffness or heavy residue, and offers heat protection up to 230°C/450°F so it’s well suited to blow-drying and heat styling routines.

Ideal for hair that appears fine, thinning or prone to breakage from brushing, this product fits easily into an everyday haircare regime. Use it after cleansing and conditioning with the Acidic Grow Full System Shampoo and Conditioner, or alongside your usual wash routine, to help promote the look of denser, more resilient hair. Hair is left feeling soft and touchable, with enhanced lift and a naturally fuller appearance.

How to Use:
Start with freshly washed, towel-dried hair. Hold the bottle around six inches away and mist Redken Acidic Grow Full System Instant Densifying Spray evenly through damp hair, focusing on the roots and mid-lengths. Comb or brush through to distribute the formula, then blow-dry or style as desired without rinsing.

Frequency:
Use as needed after each wash or according to the product instructions.

Application Technique:
Apply to clean, damp hair before styling. Spray in light, even passes rather than saturating the hair, then work the product through with a comb or fingers to ensure even coverage before using a hairdryer or heat tools.

Best Practices:
For a complete routine, pair with Acidic Grow Full System Shampoo, Conditioner and Scalp & Hair Serum. Concentrate extra product at the roots if you want more lift, and avoid over-applying on very fine ends to keep the finish light.

Safety Tips:
Avoid contact with eyes. Use externally only. Discontinue use if irritation occurs and follow any additional guidance on the packaging. Keep out of reach of children.
