How often should you wash your hair?

How often should you wash your hair? It’s a question we get asked a lot at the salon, and the answer depends on a few different things…

If you wash your hair too much, you can remove the sebum your scalp produces - this is vital to healthy, shiny hair. And don’t be scared of oily hair, because despite what shampoo brands want you to believe, washing your hair a lot can turn your good hair day into a bad day.

Most people don’t need to wash their hair every day or even every other one, and how often you do it depends on quite a few factors. The simplest answer is that you should wash it once it’s oily and feels unclean to the touch.

But what other factors influence how often you need to wash your hair?

OIL

Oil is probably the biggest culprit behind what most people consider dirty hair, and it can leave hair limp and clumpy. How much oil you produce will depend on your age, genetics, sex, and environment. Kids and older adults don’t produce as much sebum as teenagers or 20-30 year olds.

TYPE OF HAIR

Straight and thin hair will need to be washed more often than thick or curly hair. This is because straight hair is easily coated by sebum, so it’ll look greasy faster. Thick, wavy or curly hair tends to be dry because the oil doesn’t coat the strands as easily. Sebum is actually a crucial part of well-defined curls, because curly hair needs more moisture to stay soft and prevent frizzing.

SWEAT

As you might expect, a sweaty workout does your hair no favours. How much you sweat is a big factor in how often you ought to wash, or at least rinse, your hair. Sweat can spread sebum and make your hair look and feel dirty. It can also cause your hair to smell.
