How Often Should You Really Wash Your Hair?

Is there anything more relaxing than a hot shower?

And while you're in the shower, you might as well wash your hair, right? After all, that's what they told you when you were a kid. Ah, but you're not a kid anymore, and washing your hair every single day might actually be causing damage to it! (And by the way, depending on your skin type, you might not actually need a shower every day either, but that’s another blog post…)

So, if you shouldn't wash your hair every day, then how often should you break out the shampoo? Well that depends on several factors, including how much oil your scalp produces, your hair length, and the type of shampoo you use.

Hair Type

Here is the trick when it comes to shampoo: if you wash your hair too often, you're going to dry it out and damage it. If you don't wash it enough, you're going to have dirty, greasy hair. So, where's the sweet spot?

Generally, you must wash straight and thin hair more often than curly or wavy hair. That’s because straight hair is more easily coated by the oil that your scalp produces (sebum). It’s one of the reasons why straight hair is often easier to keep healthy and strong than curly hair. Isn’t that interesting? As straight hair tends to have more oil coating it, it has a layer of support and protection that curly hair doesn’t. It’s quite fascinating!

Beware Too Much Shampoo!

No matter your hair type, there can be pitfalls to shampooing too often. While hard scientific evidence is somewhat scant, it's believed that the more often you wash your hair, the more oil your scalp will produce. Why? Because if you shampoo every day, you’re stripping all of the natural oils from your hair that keep it healthy and shiny. As a result, your body may start to overcompensate by producing even more oil to protect it. Many hair professionals say that the less often you shampoo, the less sebum your scalp will produce.

That said, you certainly shouldn't avoid shampoo altogether either. Many people consider the sweet spot to be a hair wash every three days. This guideline doesn't mean that you can't give your hair a regular rinse in warm water every day or so. Just make sure sure to avoid super hot water, as that could cause additional hair damage.

Scalp & Hair Issues

Unfortunately, you also have to be careful about under shampooing. While over shampooing isn’t a good idea, under washing has its own share of issues and can lead to scalp problems. In fact, not washing enough can lead to hair loss overtime, because the oils and debris can build up on the scalp and suffocate the hair follicles. It’s also important to note that we don’t support the ‘no poo’ strategy. It’s all about finding the right shampoo and washing frequency for you.

Between Washes

With that in mind, there are two products that you should also have in your bathroom or shower. Even if you aren't washing your hair daily, using a conditioner can be a great idea! An excellent organic conditioner will help protect your hair and keep it healthy and strong.

If you’re a bit worried that your hair is getting greasy between washes, you could also invest in a great-quality dry shampoo. This "shampoo" absorbs some of the oil in your hair, refreshing your 'do every time you use it. Of course, you need to be aware of how much you use. Like with any hair care products, it can build up. We recommend only using dry shampoo once between washes, if necessary. At Thair we use Kaia dry shampoo and Organic Colour System dry shampoo. We chose these brands because they aren't aerosol, they are in powder from, they are much better for environment, and have no chemicals.

These are, of course, only suggestions. If you have excessively oily hair or use a ton of product, then daily shampooing might be a necessity. If that’s the case, however, you need to be extra careful about the type of shampoo you use.


Whether it’s in soaps, shampoos, or other kinds of cleaners, you should be avoiding sulfates in your products.

Sulfates are cleaning chemicals that strip away all oil and dirt—but they’re harsh. They’re what’s responsible for all of the suds and lather when you give your hair scrub. Sounds great, right? Well, not necessarily.

Sulfates will strip away all of the natural oils from both your hair AND your scalp. On the hair front, this can cause your beloved hair to become dried out and brittle. If you’re worried about dandruff, using a shampoo with sulfates can dry out your skin, leading to even more flaking!

Thankfully, sulfate-free shampoo and other body cleaning products have become much more popular over the last few years. Here at Thair, you’ll only find organic, sulfate-free products. For an amazing moisturizing shampoo, at Thair we use John Masters and Neuma. And if you want some outstanding sulfate-free hair care products to take home, we have some great products we can help you with your specific hair needs.

If you want to make sure that your hair is strong and healthy, while also shiny and eye-catching, then we invite you to drop into Thair Hair Boutique and Spa! We offer several fully-organic hair care treatments, including cuts, blowouts, colouring, deep conditioning treatment, and more! Please don't hesitate to book an appointment with us today.
