Hygiene - Hair. KERASTASE Extensioniste Bain 500ml Shampoo. Unlock your hair´s full growth potential with Kérastase Bain Extentioniste, a revolutionary length-strengthening shampoo designed for those who dream of long, resilient, and beautifully healthy hair. If you struggle with slow-growing, brittle, or damaged hair that seems to break before it can reach its desired length, this shampoo is your essential first step towards achieving your hair goals. It acts as a personal trainer for your hair, fortifying it from within to encourage magnificent length. This advanced formula is expertly crafted to target the very core of the hair fiber, reinforcing its internal structure from root to tip. With each wash, it actively works to rebuild and strengthen weakened strands, drastically reducing the risk of breakage. The result is hair that is not only cleansed but fundamentally stronger and more resilient against daily stressors like brushing, heat styling, and environmental factors. Bain Extentioniste goes beyond simple cleansing. It thoroughly purifies the hair and scalp, creating the optimal environment for healthy growth. By stimulating the scalp and protecting the hair fiber, it ensures that new growth is strong, vibrant, and prepared for the journey to great lengths. Its powerful action improves the hair´s natural elasticity, allowing it to stretch and bend without snapping, a crucial quality for maintaining length. Experience a transformation in your hair´s texture and appearance. This luxurious shampoo envelops the hair in a rich, creamy lather that gently removes impurities while delivering its potent strengthening benefits. Hair is left feeling incredibly soft, smooth, and with a brilliant, healthy-looking shine. It becomes more manageable and prepared for the subsequent treatments in the Extentioniste range, such as the fondant, masque, and serum, which work in synergy to maximize results. This 500ml professional size ensures a long-lasting supply for your dedicated hair-strengthening routine.
