BioTech Blowout™ Hair Mask

Why you'll love it: You don't need a blowout to recap the benefits of this leave-in treatment, but it doesn't hurt. Actually, it's encouraged.

How you'll use it: After shampooing and conditioning, rake in a dime-size dollop of this lightweight cream from mid-lengths to ends while hair is still slightly damp. Then grab your blow-dryer to dry and smooth strands—or skip the heat altogether and air-dry—without damage.
