If you condition your hair too much, your hair can appear greasy. If you condition your hair too little, you might find your hair getting tangled and feeling dry. Finding the right balance comes down to your hair type and the type of conditioner you use. Conditioner options include: Rinse-out conditioner: You can use a standard conditioner every time you wash your hair, typically a few times each week. People with fine or oily hair may want to condition less often, while those with coarse, curly, dry, or color-treated hair may condition more frequently. Leave-in conditioner: This type stays in your hair until the next wash. You can apply it once a week, but you'll want to use it more often if you have curly, damaged, or dry hair. Deep conditioner: This heavier conditioner helps with damaged or dehydrated hair and should be used once every month.
