A leave-in conditioner is supposed to provide moisture, help detangle hair, and be a protective base for all other styling rituals. But is your leave-in handling business properly? Nubian Heritage's Honey and Black Seed Heat Protect Leave-In Conditioning Cream ($13) pulls its weight without weighing hair down. Carrot oil shields hair from scorching temperatures of heat styling, black seed oil heals the scalp, and Arabian honey hydrates and seals in moisture. And because this cream is meant to serve as a heat protectant, the formula is lightweight, not greasy. It also performs well sans heat. Applied underneath a styling gel, it leaves a soft, touchable hold on even coarse strands with no white flakes or crunch left behind. As for detangling, this conditioner gives a slippery surface to your strands; a comb will glide through like butter. Maybe it's time to put your leave-in conditioner up for review.
