Applying coconut oil before shampooing on gray hair; what it's for and why this care protects the strands

Millennials are rediscovering pre-shampoo oiling for their emerging gray strands. Coconut oil effectively reduces protein loss from hair during washing. Gray hair becomes drier as scalp sebum production declines with age. Oiling hair before shampooing softens strands and reduces split ends. This practice complements conditioner, offering a simple way to manage hair texture.
