This Anti-Humidity Spray Kept My Hair Sleek & Styled All Day In 90 Degree Weather

Anyone who’s braved a summer in New York City knows one of the biggest pain points is the level of humidity one must endure. It’s inescapable, from the subway platforms (where it’s arguably at its worst) to even your own apartment on particularly hot days. For those of us who like to routinely style our hair , this can be especially annoying—spend even five minutes outside, and every bit of effort is replaced by frizz.

Therefore, I’ve been on the hunt for a product that can help shield my hair against the city’s mugginess. I came across the Bold Uniq Anti-Humidity Spray , a leave-in treatment (which happens to be down to $17 during Amazon Prime Day) that keeps hair in check in the grossest of weather conditions—the brand literally calls it an invisible umbrella for your hair.

All hair types, from straight to curly, can reap the product’s benefits of protecting your styling from the ruins of humidity. One caveat is that you can’t just spray it across your damp locks and go—heat is initially required to activate the treatment’s effects. But take note, its anti-frizz technology will last for up to four washes.

The formula contains smoothing and sealing compounds that keep unwanted moisture from targeting your strands. Instead, it leaves behind a shine, softness and sleekness remnant of a post-salon blowout. It will last, too—I use it alongside a blow dry brush, and over the next two days the look of it will remain intact, almost perfectly. I’d almost call it sorcery in a bottle.

I hate the feeling of product residue in my hair, so I was happy the anti-humidity spray disappears into damp strands immediately; you won’t notice it at all, even if you spray it across your roots.

If humidity has been making your hair routine all the more miserable, consider giving the Bold Uniq Anti-Humidity Spray a go this summer, especially while it’s down to $17 during Prime Day.
