Redken Acidic Growth Full System Densifying Shampoo for Thin Hair, Strengthens & Thickens 300ml

Redken Acidic Grow Full System Densifying Shampoo is a lightweight, pH-balanced shampoo designed for thin or fragile hair that’s starting to feel flat. The fluid texture creates a soft lather that gently lifts away impurities while helping to support a comfortable, hydrated scalp. Infused with azelaic acid, caffeine and a 7% densifying complex, the formula works to promote the look of fuller, thicker hair without leaving lengths heavy or coated, making it a considered choice for fine hair that needs body as well as care.

Suitable for all hair types, including colour-treated hair, this shampoo fits easily into a daily or regular haircare routine whenever hair needs a fresh, volumising cleanse. Used consistently as the first step in the Acidic Grow Full System, it helps to reduce the feel of breakage from brushing and encourages hair to appear stronger and more resilient over time. Simply massage into wet hair, enjoy the fresh citrus-inspired fragrance, then rinse thoroughly before following with conditioner and the rest of your chosen routine.

How to use
How to Use:
Apply to thoroughly wet hair. Massage the shampoo into the scalp and roots to create a gentle lather, then work it through the lengths. Rinse well. Repeat if desired, then follow with Acidic Grow Full System Densifying Conditioner and the rest of your chosen styling routine.

Frequency:
Use as needed or according to the product instructions, as part of your regular hair-washing routine.

Application Technique:
Focus application at the scalp first, using your fingertips to massage in small circular motions to help lift away product build-up and excess oil. Smooth the remaining lather through mid-lengths and ends before rinsing thoroughly with warm water.

Best Practices:
Use on wet hair only and ensure the scalp and lengths are fully saturated before applying. Rinse until the water runs clear to avoid residue weighing hair down. For thin or fragile hair, follow with a lightweight conditioner and, if desired, the complementary serum or spray from the same range.

Safety Tips:
For external use only. Avoid contact with eyes; if this occurs, rinse immediately with plenty of water. Discontinue use if irritation occurs and keep out of reach of children. Always follow any additional guidance on the product packaging.
