For optimal results, pull your hair back into a loose bun and slide the shower cap over your hair, adjusting the elastic at the hairline. KLORANE BEAUTY TIP: For an enhanced deep conditioning treatment; apply your favorite Klorane hair mask and cover hair by turning your shower cap inside out so that the terry fabric is outside. Rinse hair with water after treatment. SHOWER CAP CARE: Daily: After each shower hang up to dry. Deep clean: Turn shower cap inside out and machine wash on gentle cycle. Do not place in the dryer. Hang dry only.
