Give your hair some ‘bonding’ time keratin. Whether it is split ends, frizz or damage repair, keratin is one ingredient that should be a must-have in your winter hair care routine. It smoothens out overlapping cells in your hair, adds volume, shine, softness and makes it healthier over time—something we all need in these dry months. Look out for keratin-rich shampoos and conditioners to elevate your wash days without any extra effort.
