“Why does my hair get so greasy after even just a day?” I remember asking my mom in middle school. All of my friends could go days without washing their hair. Mine looked like I could fry an egg on it a mere 16 hours later. That was precisely when my fight against my oily hair ensued. From “scalp training” (doesn’t work for me) to slicked-back hairstyles (fine, sometimes) to all the dry shampoos in the world (made my scalp itchy over time—ugh), I’ve tried just about everything out there to get my hair wash to last longer. Turn’s out, the answer was kinda simple all along: the right shampoo for oily hair.
De-gunking my scalp has been key to unlocking fewer necessary hair-washing days. But what exactly constitutes a shampoo for oily hair specifically? It’ll depend a bit on your exact hair type, but a cleanser with enough surfactants to break down grease is imperative. I’ve tested hundreds of shampoos over the years (seriously) and have narrowed down a list of my absolute favorites that have to live in my shower at all times. Plus, of course, I consulted a few Cosmo staffers with different hair textures and lengths to test a few other formulas—a mix of iconic shampoos and new ones to the market.
