After conditioning, rinse your hair in cold water. This simple trick will close your hair cuticles, helping to seal in the moisture. Cold water will also close the pores, preventing dirt from entering, and accumulating on the scalp.

And if that’s not enough, a cold water rinse can close the scales of your hair cuticle, which not only prevents frizz, but adds luster to those beautiful locks.
