How often should you wash your hair?

For someone who has a lot of hair, you might be wondering how often you should wash it? Some of us wash our hair every day while others leave washes to once a week. If you want to know how often you should wash your hair, you will be happy to know that it’s actually better to wash your hair less, not more. Let’s take a closer look at this rather interesting data point.

Don’t wash it too much

It is important that you don't over wash your hair. One of the main reasons to avoid regular washing of your hair is that it can lead to dry, damaged, and brittle hair. It’s hard to find the key middle ground, though, so we recommend that you get into the habit of washing to suit your style of hair. If your hair is very thick hair you may be able to go longer between washes without your hair feeling greasy. If you have very fine hair you may find that you have to wash it more often to keep it looking fresh.

What about coarse hair?

If you are one of the lucky ones to be born with nice course hair, then you can get away with washing it far less often. You can find that coarse hair is the kind of hair that does not need regular or frequent washing. However, the opposite is that those with straight and silky hair will need more frequent washing.

Do you have a busy life style?

Another factor that many people are not aware of is that having a regular lifestyle that involves exercise can help you out. If you are someone who is exercising a lot, then you will find that your hair is naturally oilier. This is because your body is pushing a lot more oil out of your pores. The sweat is building up, and your pores get all clogged up. This makes your scalp get dirtier faster. So, if you do a lot of working out, expect to wash your hair slightly more often.

So, how often should you wash your hair?

If you are going to be caring for your hair as best you can, then we recommend that you mix it up to suit your hair type. If you have dry hair then try washing every 3 days or so. The more you wash your hair the dryer your hair can become as your hairs natural oils are being stripped away. If you have an oilier and naturally moist hair type then you will need to wash your hair more frequently maybe even once a day. Most thicker hair types can often go with washing only once or twice a week.Typically, giving your hair a daily rinse with water is a good idea – but make sure the water isn’t too hot, or it can damage your hair if done too often. Regular washing with water is a good thing to keep your hair and scalp clean, however only use shampoo on your hair when you really need to depending on your hair type.
