Kereffect™ SD-LQ-(WD) (Aqua (and) Hydrolyzed Keratin) is a revolutionary hair treatment designed to cater to all hair types, from gentle waves to the most defined curls. This unique low molecular weight hydrolyzed keratin offers a versatile approach to hairstyling, enhancing the efficacy of sodium sulphite for a mild yet effective straightening alternative. For individuals with curl types VI to VIII, it beautifully loosens tight curls, creating naturally defined and manageable hairstyles. Meanwhile, for curl types III to V, Kereffect™ facilitates reversible, semi-permanent straightening that lasts up to 30 washes, depending on styling habits. This product provides a flexible and less damaging solution for those wishing to experiment with their look without the long-term commitment often associated with traditional straightening methods.
