How to Care for Tight Curls 

Since this hair type is typically very dense, air can't easily reach the scalp, says celebrity hairstylist Chuck Amos, who works with Lupita Nyong'o. He recommends massaging a few drops of tea tree oil into roots before cleansing; this can help stimulate blood flow and reduce inflammation.

Grab a smooth, wide-tooth comb to separate and detangle tight curls without snagging, says Amos. Maintain the texture's natural volume by combing through strands during the conditioning process, when hair is well lubricated and has more slip.

Once a week, add two or three drops of nourishing natural oil—pro Vernon François, who also works with Nyong'o, suggests argan, jojoba, or rosehip—into a deep conditioner. Sleep with saturated strands, then rinse in the morning for maximum hydration.

Your goal is to retain as much moisture as possible with a nonfoaming formula, says hairstylist Rodney Cutler. " 'No foam' means the blend has cleansers that won't strip hair of its natural oils," he says.
