This is for people with curly, wavy, frizz-prone, or color-treated hair who deal with puffiness and lost smoothness in humid weather. It's a consumer, at-home product, but since the polymer only activates with heat, it's best suited to anyone who already blow-dries their hair rather than someone looking for a no-heat, leave-in fix.

Most anti-humidity sprays sit on top of the hair shaft and can leave it feeling coated or heavy if you use enough to actually block moisture. Dream Coat's polymer is designed to compress and seal the cuticle itself when heat-set with a blow dryer, which is the reason Color Wow markets it specifically at color-treated and porous hair rather than as a general finishing spray.

1. After shampooing and conditioning, apply to damp, towel-dried hair.
2. Divide hair into sections and spray each section thoroughly, both on the surface and underneath, so it's fully saturated, then comb through to distribute evenly.
3. Blow-dry section by section, using a brush to hold hair taut while directing the dryer at medium-to-high heat down the length of the section until completely dry — this heat step is what activates the polymer.
4. Effects typically last through 2 to 3 shampoos before reapplication is needed.

The main strength of Dream Coat is that it seals hair against humidity for 2 to 3 washes without the greasy build-up that heavier anti-frizz serums can leave behind, which matters most for porous, color-treated hair that swells and frizzes easily in damp air.

The trade-off is that it only works if you complete the full blow-dry step; sprayed on and left to air-dry, the polymer won't activate the way it's designed to. It also needs reapplying every few washes rather than lasting indefinitely, and its ingredient list is silicone-based rather than natural.
