Think of the smoky brunette color like the hair equivalent to makeup's smoky eye. It's just as seamlessly blended and meant to give a deep, sultry look. The difference in this shade of brown compared to others is that it typically features cool undertones. The ashy hue gives off an edgy, mysterious vibe and is the perfect choice for anyone looking to make a small tweak (but get a big impact).
The trend works best on someone who has a light, medium, or dark brown, or dark-blond hair already. According to hairstylist Jamie Mazzei, the hue looks the most flattering on skin tones with cool undertones, but if you have warm undertones, work with your colorist to custom blend a shade to make it suit your skin tone.
Your stylist might choose to add in cool-toned highlights, tone highlights you already have, do a color melt, or give your entire head one all-over hue — all depending on whether you already have highlights or are working with virgin hair — but either way, smoky brunette is the perfect dimensional, ashy brown idea for summer.
