Leila's one habit for glossier hair, and it costs nothing.
Cotton pillowcases drink oil and rough up the cuticle. A silk scarf, loosely tied, keeps the gloss we put in for weeks longer.
Leila ties hers in a low knot at the nape; Ama prefers a bonnet for curls. Either works. The trick is to start the night you leave the salon.
Wash less, rinse cooler
Two washes a week, a cool rinse at the end, and a wide-tooth comb in the shower. That's the whole routine.
