Here's Exactly Why Your Hair Is So Greasy All the Time

The co-washing trend has hit peak popularity. If you're not familiar, it's essentially the process of washing your hair with only conditioner. This can have a great effect when done sparingly or for drier scalps. However, if you're naturally oily, you may be left with limp, greasy hair. Another culprit might be deep conditioning your hair too frequently or using a deep conditioner on your scalp instead of isolating it to the mid-shaft and ends.

Opt for a clarifying shampoo, such as Neutrogena The Anti-Residue Shampoo, $5.29, to nix buildup and oil and then get yourself on a regular hair-washing regimen.
