Palm rolling
Rolling each loc between the palms to tighten new growth and keep the loc round.
Palm rolling is a gentle maintenance method for locs. Each loc is placed between the flat palms and rolled back and forth, usually in the same direction each time, often with a little cream or gel. It helps new growth at the root lock into the loc and keeps the loc smooth and cylindrical. It is slower to tighten roots than retwisting or interlocking but kinder to the hair.
