For years, we’ve heard over and over again how you shouldn't wash your hair everyday. That it strips the natural oils and dries out your scalp. That skipping shampoo gives your hair a natural boost in body, volume and shine. But honestly, not washing your hair can quickly go from bad to worse. Depending on your lifestyle and the grooming products you use, you'll notice that your hair feels grimy or your scalp feels itchy. Those with thick hair might find it feels too chunky, while fine hair can get weighted down by oils and fall flat. Then there's the possibility that the stands aren't smelling so fresh either. So what's a self-respecting guy to do when he wants good looking and clean hair but doesn't want to strip it of all those beneficial oils?
You co-wash it. Co-washing is shorthand for simply washing your hair with conditioner instead of shampoo. Just try it for a day or two and notice how different your hair looks, feels and behaves after you towel it off. It's less brittle, less frizzy. Your hair has an instant, nice shine and the perfect malleability for styling.
I used to stay away from conditioner altogether because I've got naturally wavy hair. After shampooing and conditioning, I got that dreaded dry and wiry (“poufy” for lack of a better word) hair that took way too much product to tame. But the more I heard about co-washing, I figured I'd give it a try and decided that if I was going to skip shampoo, I should use a quality conditioner. The better bottles are not only formulated with strand-strengthening ingredients, they contain trace amounts of detergents called cationic surfactants (common types that you can find on your conditioner's ingredient list are cetrimonium and behentrimonium chloride). These are much weaker cleanser compounds than shampoos, but are enough to get your hair nice and clean.
Now I'm co-washing my hair every other day—between those days I simply rinse out any product with warm water in the shower. And I can confirm the method's success. My hair looks and feels smother. It's also more pliable and easily styled. It never gets dried out the way it did in the past. But best of all, it's just one step and never takes as long as rinsing out all the suds from shampooing. Which means I'm able to save some precious time getting ready in the morning.
