Granting silky-soft strands with added bounce, the Hair By Sam McKnight Cool Girl Volume Cleanse is a clarifying formula that breathes life and body back into lacklustre lengths. Developed with the brand’s innovative voluminis™ active, the shampoo visibly thickens the hair to encourage a fuller look, while delivering long-lasting moisture to plump and lift the fibres after just one wash. Pro-vitamin B5 and fermented rice water work in unison to soothe and nourish, providing gentle hydration and antioxidant benefits for a stronger-feeling finish. Plus, the low-lathering formula holds the Kind to Biome accreditation, meaning it supports the scalp microbiome and protects from flakes, dryness and redness, making it suitable for those with sensitivities.
