Experts Weigh In: How Long Can You Go Without Washing Your Hair?

How long would you go between hair washes? We decided to get an expert opinion on the matter so we called up Brandon Martinez -- hair stylist and creator of B. The Product -- who told us, "Just in general people don't need to wash their hair as often. For girls, try to stretch it out, especially if you color your hair."

Indeed, nothing kills your color faster than frequent lathers, especially for red or brunette colored hair.

Martinez told us that guys don't really ever need to shampoo, unless they use tons of products or have gotten really dirty. He himself only shampoos when he's been surfing because the water is salty.

But we're not off the hook yet: Sarajane Lynch, creative director of the NYC salon Ion Studio explained that there can't be a one-wash-fits-all mentality because different hair types have different needs.

"Coarse, curly, dense textured-hair can go longer without washing because that type of hair is more dry and it absorbs the oil," she said. "It's more beneficial for people with that hair to notwash every day." Oil equals natural moisture for coarse hair.

Lynch herself washes every three days and prefers her hair in the unwashed state because "it performs better -- fresh, clean hair doesn't hold shape." Some people can't imagine not washing every day, even if their hair isn't oily, and Lynch says, "I think it's psychological. People get in the shower and think they have to wash from head to toe. People don't want to be 'dirty.'" Of course if your hair actually is dirty, no one is suggesting you shouldn't wash it. But how "dirty" are you really getting if all you're doing is going to and from the office every day?

So what about fine-haired gals who hate washing their hair every day but start to look like a greaseball by day two? Can you retrain your scalp to hold out? There is some speculation among stylists that drying your scalp out every day with shampoo prompts it to compensate by making more oil, and if you stop washing your hair every day eventually your scalp will adjust.

"It would be worthy of an experiment," says Lynch. So if you're a die-hard everyday washer, why not try out every 2 days for a few weeks and see how it goes?

Both Martinez and Lynch recommend dry shampoos to refresh your roots in between washings. B. The Product Dry Cleaned and Rene Furterer Naturia Dry Shampoo are two good ones to try.

What do you think? Would you ever try going a week without shampooing, or are you addicted to a daily lather? Let us know on Twitter with the hashtag #MyWashStyle!
