Redken's Extreme Length leave-in treatment, enriched with biotin and soy proteins, penetrates the hair fiber to strengthen and seal split ends. Used in conjunction with the shampoo and conditioner from the same range, it visibly reduces split ends by up to 78% and decreases breakage by up to 81%. Its lightweight texture makes styling easier, adding shine, softness, and suppleness. It promotes smoother, healthier, and stronger hair every day. Apply to clean, towel-dried hair, leave in, and then style as desired.
