How does heat affect the hair during the conditioning treatment?

Heat during a conditioning treatment helps to open up the hair cuticles, allowing the conditioning agents to penetrate more deeply into the hair shaft. This enhanced absorption can lead to improved moisture retention and overall hair health. Additionally, heat can activate certain ingredients in the conditioner, boosting their effectiveness and promoting smoother, shinier hair. However, excessive heat can also cause damage, so it's important to use it judiciously.
