All sorts of water based products, gels, and wetting of the hair are all excellent and should be used regularly to avoid hair dryness and breakage. Castor oil is a preferred oil of mine because it prevents and eliminates any sign of dryness in between washes and after long days in the sun and wind. I am able to keep my hair protected from the elements and keep it from suffering dryness and at the same time prevent shrinkage from adding water. I use this natural oil on the days I don't wash my hair.
