No wet beading or added weight. Flexible holding polymer dries instantly and allows hair to be brushed without residue. This resilient polymer features the unique ability to ÂmemorizeÂ shape even after brush through. Polishing & conditioning agent for brilliant, natural shine and powerful humidity-shielding effects. Helps protect hair from damaging external elements and dulling, color-dimming residue.
