Conditioners mimic the function of natural oils in your hair by making it softer and shinier. Hair conditioners also neutralize the static electricity of flyaway hair to prevent frizziness and increase manageability. The regular use of a conditioning product will provide protection and keep your hair looking and feeling its best. If you have oily hair, apply conditioner only on the ends and avoid the scalp. However, if you are using an anti-dandruff conditioner, the product should be applied to both the scalp and shaft. Some anti-dandruff formulas are gentle enough for daily use or even on normal or chemically treated hair, so you wonot have to purchase multiple products to suit the variety of hair types in your house.
