Ouidad's Advanced Climate Control® Flexible Holding Spray is a non-aerosol, alcohol-free hairspray for curls that provides a lasting, crunch-free hold and helps fight frizz in any climate. Made with flexible polymers that set curls in place and pro-vitamin B5 for healthier-looking curls, this holding spray helps keep curls voluminous and defined without drying out hair. The brand's signature high-performance Anti-Frizz Nano Technology® with sericin, a protein derived from silk, forms an invisible barrier to block out humidity that causes frizz. “Nano” Technology refers to the size of the molecules in the formula, which are small enough to penetrate the cuticle and provide maximum frizz-fighting benefits. Safe for color-treated curls.
