What is the function of a conditioner?

A conditioner plays a crucial role in hair care by primarily moisturizing and detangling hair. When hair is washed, especially with shampoos that can be drying or stripping of natural oils, conditioners are essential to restore moisture and hydration. They help to smooth the hair cuticle, making it easier to comb and reducing tangles. This moisturizing effect helps to maintain softness and manageability, leading to healthier-looking hair.

Additionally, conditioners often contain ingredients like silicones, which can help to create a barrier that protects the hair from environmental damage while also assisting in reducing frizz and promoting shine. However, their primary function remains to hydrate and detangle, making this option the most accurate representation of what a conditioner is designed to do.
