Go big or go home with the Grow Gorgeous Intense Thickening Shampoo Supersize. This shampoo stars a body-building formula that’s both results-driven and cost-effective. Perfect for fine or flat hair types, the cleanser gently dissolves impurities while supporting a fuller-looking mane. Biotin helps to energise the roots, and niacinamide resists water loss by supporting the scalp’s protective barrier. Enriched with rice protein to volumise and amino acids to nourish, the shampoo helps to leave your strands with a shiny and thicker appearance. Complete with caffeine to invigorate from root-to-tip.
