"I'm always looking for sneaky ways to get more moisture into my haircare routine without weighing down my fine hair. The KMS Moist Repair Style Primer ($25) is ideal because there's both an in-salon treatment version that lasts through seven washes and an at-home version for maintenance that last two to three. It doesn't feel like I have another product in my hair, but it's definitely there, creating just the right amount of softness and hiding my split ends." — Dawn Davis, senior content director, Beauty
