Justin and Hailey Bieber have been known to share this one in the shower, and if that's not incentive enough, it's instantly effective for keeping platinum blondes as icy as possible.

One spritz - and seven seconds - is all you need to get heat styling protection and a glossy finish.

I use UNITE BOING Curl Leave-In Conditioner every time I shower, and sometimes in the mornings, to define and smooth my really long hair. I'll also apply it when my hair is in braids if I have a lot of flyaways.

UNITE U:DRY™ High Dry Shampoo works on even the oiliest of hair to add volume and texture even after you've skipped a few washes.

Work this cream through wet hair before styling for a very sleek, glass-like, shiny finish that locks in moisture and defies humidity.

UNITE's BLONDA Toning Shampoo helps restore the rich color you want in your hair, rather than having a dull, yellow or brassy finish.

UNITE is one of my all-time favorite haircare brands, and they actually have two different shampoo options for blonde hair. If you're looking for a true purple shampoo and conditioner, however, I recommend these two.
