While some conditioners are designed to be leave-in treatments, traditional rinse-out conditioners are meant to be washed out to avoid these issues.

Leaving on your conditioner for a few extra minutes won't cause any immediate problem. But if it becomes a habit, the extra conditioning time can leave your hair feeling coated with product build-up.

A leave-in conditioner is safe to apply on dry hair, especially those who have the characteristics of dry (dehydrated) hair and those that are blessed with texture.

Cold water should be used when rinsing out the conditioner from your hair at the end of wash day. This is because cold water closes the hair cuticles and pores in the scalp. This process adds luster and shine to the hair as the cuticles have been closed.

Reduced Stripping of Natural Oils: Shampoos, even gentle ones, can strip your hair of its natural oils. By using only a conditioner, you're skipping this potentially harsh step and retaining more of your hair's natural moisture.
