Encourage thicker, fuller-looking lengths with the Hair Gain Nourishing Hair Mask. Thanks to the brand's exclusive AnaGain technology, the potent formula seeks to visibly strengthen the strands from the follicle to promote resilience. A blend of organic pea shoots, beet-derived betaine, panthenol and phytantriol helps to protect the hair from heat damage and reduce the appearance of split ends, while visibly intensifying colour and vibrancy.
