Ever wondered how often you should wash your hair? If so, you’re in good company. Because we have all asked that question at some point! And to say opinion is divided is perhaps the hair care understatement of the century. The debate has raged for years. Some insist daily shampooing wrecks your hair, while others are adamant that it is essential not just for cleanliness but also for healthy growth. However, recent research has given the hair-washing mood music a fresh twist. The reality (as with most things in hair care) seems to be far more nuanced than you might think. Here’s the lowdown.
Is It Bad to Wash Your Hair Every Day?
For decades, the belief that daily washing damages hair has been widely held and repeated. Perceived wisdom held that if you washed hair too frequently, then the products would end up stripping moisture and essential oils from the hair. And the scalp wasn’t safe from the ravages of a daily hair wash either, because the removal of sebum (the scalp’s natural oil) would stimulate the scalp to produce excess amounts to compensate, throwing the scalp into imbalance.
Key Studies
Two landmark studies into hair cleaning practices have changed the conversation. Firstly, a 2017 review found that frequent cleaning with a well-formulated shampoo would not damage hair. But, there was an important proviso for their findings – the additional, regular use of a conditioner was essential. A 2021 study reached a similar conclusion with regard to shampooing. Participants washed their hair five to six times a week with a mild shampoo. Researchers found no significant loss of internal hair oils and no fibre damage. Moreover, regular use of a mild shampoo was associated with improved appearance.
Thinning & Breakage
One compelling reason why people worry about how often to wash hair is the sight of strands washing down the shower drain. It’s easy to link the two in your mind and assume washing causes hair loss. But before you panic, some hair loss during washing is a completely normal part of the hair cycle. Typically, around 50-100 hairs are shed each day. At these sorts of levels, what you see merely reflects normal telogen shedding. Of course, anything regularly above this can indicate an issue.
It’s also important to distinguish hair fall from breakage. Breakage occurs when the hair fibre becomes dry, weakened and snaps along the shaft. Excessive dryness increases brittleness. This really reinforces the findings of the 2017 study, which highlighted the importance of conditioning.
So, is it bad to wash your hair every day? Not necessarily. The key variable isn’t frequency—it's protection. The quality of products and their combination is paramount.
How Often Should You Wash Your Hair?
So, we come to the million-dollar question. And the answer depends largely on your hair type and the characteristics of your hair fibres, which are as individual as you. And your environment and lifestyle matter too. As a rule of thumb:
- Fine or straight hair? It tends to oil up quickly — so daily or near-daily washing often works well.
- Curly, coily or thick textures? Naturally drier. One or two washes a week may help preserve moisture.
- High porosity? Hair loses hydration fast — frequent washing needs balancing with good conditioning.
- Low porosity? Product can sit on the surface — lighter, regular cleansing may feel fresher.
- Active lifestyle or heavy styling? Gym sessions, pollution, swimming and product build-up can all shift your ideal rhythm.
Ultimately, don’t ask, "How often should I wash my hair?” Instead, ask yourself how your locks (and scalp) are responding to your hair care routine. And take appropriate action as needed.
