How To Wash Your Hair Less

It’s a common platitude within the beauty industry that infrequent hair-washing leads to healthier locks. I (a serial hair-washer) have heard this time and time again. Last month, while deliberating about my oily scalp and hair-cleansing habits, beauty assistant Sam Sasso — another oily-scalp gal — and I decided to find out once and for all whether skipping shampoo would actually make our tresses shinier, thicker, and stronger.

So we set forth on a monthlong mission to “teach” our hair to be dirty. That is, to forgo washing for two, three, or four days to see how our hair and scalp would adjust to the new regimen (and whether it would appear healthier in the process). Curious to see how we fared? We documented the entire experience in the slides ahead.
