Famous among those with curls, this category of products is suitable for all hair types. From curly, wavy, straight, to sensitive and even baby hair. Satin reduces frizz, saving you from many 'day afters'. The magic lies in the smooth surface of the pillowcase, which minimizes friction, preserving the hair cuticles and preventing dehydration. The popularity of Satin Pillowcases among those with curls is because they do not disrupt the curls.
