One of the most hotly debated topics in haircare is how often you should shampoo. If you’re most guys I know, you shampoo every single day. And if you’re like most guys I know, you’re damn certain it’s necessary, because your hair gets oily, or something. So let me say this here and now: You do not need to shampoo every day. In fact, you should not shampoo every day. The exact number depends on your hair, but think more like two or three days a week.
The Logic Behind Shampooing Less
Shampooing removes oil. And it’s totally logical to think that shampooing more would mean less oil—totally linear. But we don’t live in that kind of world, and forcing yourself to space out those washes—let’s say, every other day, to start, then you actually train your scalp to produce less oil over time. It learns and responds. For daily washers, part of the reason it gets so oily on a daily basis is because you’re washing it every day. That hair wants so badly to stay nourished, and so the scalp overproduces sebum, so that the sebum can make its way up the hair shaft and stay hydrated. By going to one extreme (the daily wash), your scalp goes to the other extreme (the overproduction of sebum). So, take it easy on your head, and simply shampoo less. Healthy hair should always focus on moisture and conditioning, not excessive cleaning.
Should You Shower Less, Too?
Now, don’t get me twisted—you should still shower daily. You can (and should) rinse your hair every day, which will flush away most oily and sweat and hair product (since most products these days are water soluble anyhow).
Plus, you can, and should, use conditioner as much as you want, though daily might be a stretch for many guys. If you have more textured hair, it’s also worth trying to co-wash (“conditioner-wash”). This is where you let your fortifying conditioner help rinse away excess grime and oil buildup. This could buy you time between shampoos—perhaps a couple extra days.
While we’r on the topic of conditioner: Any time you shampoo, you should always follow it with a conditioner. (Don’t even get us started on 2-in-1 products, which you…
