Standard Process for the "Three-Piece Sleep Set" Step 1: Gently detangle your extensions with a hair extension brush or comb, starting from the ends and working upward.Step 2: Secure your hair in a loose, low braid. Avoid tight or high ponytails, which can create unnecessary tension on the scalp and extensions.Step 3: Wear a silk sleep cap or use a silk pillowcase to minimize friction and help prevent tangling while you sleep.
