Hair feeling dirty and heavy.

Here are some of the hair care mistakes that you could be making, from the list of The Dirty Dozen: 12 Hair Mistakes You May Be Making:

1. Washing your hair every day—or more. While we’re not advocating the greasy grunge look circa 1992, it can be good for your hair to get a break from daily washing, drying and styling. If you color your hair, skipping the shampoo on occasion will help your shade stay rich longer since the sulfates in many shampoos fade away color. And for all but the oiliest heads, daily (or even twice daily if you hit the gym) washing can strip away too much of your natural oil, leaving hair dry, brittle and more susceptible to breakage. Try every-other-day washing, and if the roots look a little greasy on day two, sprinkle on some dry shampoo or hair powder and brush it out thoroughly.

2. Using too much conditioner. It makes sense that fine hair will get weighed down by excessive conditioner, but even dry, coarse hair may not need as much as you think. “If you routinely use too much, the product can build up on your hair and leave a residue that makes hair appear dull and lifeless,” says Cohen. Try using the lightest formula your hair can handle (a detangling rinse is perfect for normal to fine hair), and doing an occasional deep treatment if hair needs it. And when you apply your conditioner, skip the areas closest to the scalp and concentrate the product more toward the ends of the hair.

3. Choosing the wrong styling products for your hair type. Just as you select your moisturizer and makeup to suit your skin type, you need to select the right kinds of styling products in order for your hair to look its best. Loading up your fine hair with a heavy styling cream or a silicone product will leave your locks limp. And trying to style your thick, coarse, curly hair with just a spritz of spray gel won’t tame your frizz or help hold your style all day long. For best results, look for a line of products that are designed specifically for your hair type and style.

4. Ignoring the health of your scalp. The follicles in the scalp are the birthplace of every strand of hair on your head. And if those factories aren’t kept clean and healthy, they won’t produce full, strong, healthy hair. While there are many products on the market to cater to the health of your scalp, treating it well can be as simple as giving it a little extra massage every time you wash your hair to stimulate it. And be sure to rinse all product off your scalp before you leave the shower to ensure that there’s no residue left behind to clog hair follicles.
