The primary function of a conditioner is to moisturize and protect hair. Conditioners are formulated to improve the texture and manageability of hair by providing moisture, which helps to keep the hair cuticles smooth and improves overall shine. They contain ingredients that can penetrate the hair shaft or coat the surface, resulting in reduced dryness, frizz, and breakage.

In addition to moisturizing, conditioners also help to protect hair from environmental stressors and heat styling. By forming a protective barrier around the hair, they can help minimize damage from factors like UV rays and pollution, making hair healthier and more resilient over time.

While some conditioners can aid in preventing tangling as a secondary benefit, their main purpose aligns with hydration and protection. Therefore, understanding the specific role of conditioners in hair care is essential for maintaining healthy hair.
