YOLU Calm Night Repair Shampoo refill 760ml is a gentle, deeply moisturizing night shampoo formulated to cleanse while restoring and protecting hair overnight. Its shittori (deep moisture) formula helps smooth rough, frizzy ends, replenish hydration, and strengthen strands against daily friction and breakage. Lightweight conditioning agents leave hair manageable and glossy without weighing it down. The calming floral fragrance promotes a relaxing bedtime routine. Packaged as an easy pour refill pouch with increased volume, it is ideal for people with dry, damaged, or color treated hair who want restorative care and less frequent replenishment.
