What is the primary function of conditioner for hair?

The primary function of conditioner is to moisturize and soften the hair after shampooing. Shampoo serves to cleanse the hair by removing dirt, oil, and product buildup, which can strip away natural moisture. Conditioner is then used to replenish that moisture, providing hydration that is essential for maintaining healthy hair.

Conditioners work by coating the hair cuticle, making it smoother and easier to manage. They also help to reduce friction, which can minimize damage during styling, and enhance the hair's overall texture. While some conditioners may offer additional benefits, such as thermal protection or aiding in styling, their core purpose is centered around moisturizing and softening the hair to improve its appearance and health.
