Straight Day Styling Spray is a superior daily treatment that moisturizes and protects all hair types. When used with the Keratin Complex Smoothing Therapy treatment, Straight Day replenishes the hair's existing keratin bonds to enhance treatment results while increasing shine and softness. On wet or dry hair, this hydrating spray smooths, reduces flyaways and tames unwanted frizz. The unique anti-humectant formula locks moisture in and humidity out, so hair stays silky and frizz-free throughout the day. UV filters block damaging UV rays and keep hair protected from the drying effects of the sun.
