Sunsilk Luminous 100 Hair Shampoo is a shine-enhancing cleansing shampoo developed for dull and lacklustre hair that needs renewed radiance, freshness and a smoother-looking finish. Its advanced formula is powered by a 2% Glycol and Vitamin C Complex, designed to activate hair luminosity while cleansing and revitalising the strands. The Glycol and Vitamin C Complex works as the key shine-focused technology within the formula, supporting a brighter and more illuminated appearance while the shampoo’s cleansing agents remove everyday dirt, excess oil and impurities from the scalp and hair. With regular use, the formula leaves hair feeling clean and refreshed while improving its visible smoothness and shine. Sunsilk states that Luminous 100 Shampoo can deliver up to 5 times more illuminated hair with intense luminosity lasting for up to 100 hours when used as part of the recommended Luminous 100 routine, based on technical testing against the shine provided by a non-conditioning shampoo. The shampoo is suitable for normal hair and is PETA approved, making it a cruelty-free option for an everyday hair care routine focused on long-lasting shine and healthy-looking radiance.
