How To Use

Hold canister 6-10" away from damp or dry hair. Section and apply in a sweeping motion throughout hair. Style with a heat tool. Finish with a final spray for extra smoothness and shine.


PhD Heat Styling Spray works best when you fully coat the hair from root to tip. (don't worry, it's silicone-free!) When applying to damp hair, combing will help evenly distribute all over.

If static occurs when using PhD Heat Styling Spray, make sure to finish your look with an additional application. This will help lock in the style and add more smoothness and shine.

PhD Heat Styling Spray can be used on most hair types but it works best on fine to medium hair types.
