Redken Acidic Grow Full Densifying Shampoo is a lightweight, scalp-rebalancing shampoo formulated with a 7% Densifying Complex to gently cleanse and help hair look fuller without stripping the scalp.

This compact 1.7 fl oz bottle is part of Redken’s Acidic Grow Full System designed for thin, thinning, or flat hair. The formula focuses on a mild, non-drying cleanse while supporting immediate volumizing appearance and a healthier-feeling scalp. It has been specifically evaluated in consumers using GLP-1 treatments, and it’s safe for color-treated hair when used as part of the full system.

How does this shampoo help thin or thinning hair?

The shampoo uses a 7% Densifying Complex to create a lightweight lather that cleans without weighing hair down. Instead of coating strands heavily, it lifts and clarifies the hair and scalp so styles appear fuller right after washing when paired with the rest of the Acidic Grow Full System.

• Contains 7% Densifying Complex for visible fullness when used with system
• Lightweight texture avoids residue that flattens fine hair
• Formulated to produce instant volumizing effect on wet hair

Is this product suitable for scalps affected by medication or sensitivity?

Redken tested the Acidic Grow Full System with GLP-1 users, and the shampoo is formulated to be gentle on the scalp while helping rebalance surface moisture. It avoids harsh stripping so the scalp’s protective barrier is preserved during regular use.

• Tested with GLP-1 users and consumer-evaluated in system use
• Designed to cleanse without overly drying or irritating the scalp
• Helps maintain a healthy-feeling scalp environment for styling

Can I use this on color-treated or chemically processed hair?

• Safe for color-treated hair when used as directed
• Gentle cleansing reduces risk of color stripping
• Combines with conditioning steps to protect strand integrity

How should I use this shampoo for optimal results?

• Apply to wet hair, lather, and rinse thoroughly
• Follow with Acidic Grow Full Conditioner and Scalp & Hair Serum
• Use the full system consistently for visible densifying effects
