A visit to the salon is a rare treat for some women, and an every other month ritual for others. But unfortunately, no matter how often they visit, many women are undoing what they have done at the salon by making these very common mistakes with their hair. Here's a look at two of the biggest mistakes women make with their hair care regime and how you could be damaging your hair without even realizing it.

Not Changing Products With The Seasons

Especially if you live in an area where the weather changes drastically from season to season, it's pretty important to make sure that your hair care regimen changes with the seasons. During the summer months, your primary focus should be on protecting your hair from the harsh sun. Even if you don't particularly spend a lot of time outdoors, your hair will still get more rays. In the spring and summer, make sure you use products that keep your hair moisturized and even ones that contain SPF (it's not just for your skin).

Many women tend to let their hair be a little more "natural" or "beachy" in the summer months, so it's important to use moisturizing products to help control frizz. When summer turns to fall and winter, start using moisture restoration products (which are different than moisturizing). These products help repair damage done by the summer sun. Also, summer heat gives hair more a more voluminous look thanks to the humidity. In the fall and winter, your hair will more naturally be flat and might need some volumizing help.

Using Too Much Heat

Just about every device a woman can use to style her hair - a hair dryer, a flat iron, or a curling iron - is heat-based and can do damage to your hair over time. And if you're not using the right products (as mentioned in the last point), you'll find yourself using these even more to try to get your hair to submit. If you're not using a product that helps protect from the heat (like a thermal protection spray), your hair's health will suffer long term.

The best way to make sure that your hair stays in the best possible condition is to make sure you're visiting a beauty salon regularly (six to eight weeks seems to be the standard recommendation). A regular salon visit isn't just good for the immediate care of your hair, but you'll be able to chat with your stylist - someone who likely has years of professional experience and training with caring for hair - to pick up some solid advice on what you should be doing on your own.
