If regular conditioners leave your hair feeling revifol greasy or limp, consider switching to a lightweight leave-in conditioner. These formulas are available as both, light lotions and sprays, and they tend to be much lighter than the moisture-heavy versions you use in the shower. Look for a leave-in that matches your hair type, such as color-protection sprays or anti-frizz sprays.
Make sure you only apply conditioner to your hair and not to your scalp. It is the hair shaft that needs to be conditioned and have the oils and moisture replaced. Applying conditioner to your scalp will only make it more oily and weigh your hair down. Start putting the conditioner on your hair from about midway down all the way to the tips.
