Custom Styling Primer claims to be "formulated with your unique styling goals and hold level to easily achieve any style." While no two bottles will be the exact same—ahem, it's customizable after all—the spray's key ingredients include "styling hybrid polymers" to prime the hair for styling, hydrolyzed rice protein to add volume and bounce at at the root and provitamin B5 to condition hair and reduce frizz. The primer also claims to offer heat protection up to 450 degrees, prevent color fading and protect against UV rays.

To create your custom spray, you'll fill out a short survey that asks about your hair type and texture, style goals, how much hold you want the primer to give your hair and more. You can even choose your primer's fragrance (or lack thereof) and scent strength.

As a perk of being Reviewed's beauty editor, I was sent the custom styling primer before it was available and have loved spraying it all over my hair when it's damp to air-dry it. I've noticed that the curls in my long, wavy-curly hair look better defined and smoother when I use this and I adore the sweet coconut scent I chose. I'm happy to have this as part of my hair-taming arsenal. I've also tested Function of Beauty's shampoo and conditioner for Reviewed, and went on to purchase it myself and recommend it to friends, so I'm not surprised I enjoy this newest item in the hair care line.
