Not using a heat protectant before styling your hair is like sticking your hands into an oven without any mittens on. This lightweight serum acts like an invisible force field for your strands, shielding them from external stressors - be it the heat of styling tools or the sun. Also great at detangling and adding shine, it acts as a one-and-done step after wash days for effortlessly manageable hair. The bottle has 2 chambers - one with a serum formula, and one with a cream formula. Both get pumped out together when pressed.Fine or short hair can use 1-2 pumps of the product. Long or thick hair may add a little more. Pump the product into your palm, then rub them to mix the two phases together. Apply evenly to the lengths of damp, towel-dried hair. Leave in and style as desired - either letting the hair air dry or styling with heat tools.
