Frizz, go ahead and take the next six weeks off

Hey, Gussi here, at-home keratin treatment’s crowning achievement. Maybe you’re looking for a smoothing remedy you can do yourself, processing in just 20 minutes, without needing to put on hard pants. Or perhaps spending a sizable fortune and a wad of hours on salon treatments isn’t really your thing. Could also be that you simply want ridiculously shiny, frizz-free, fuss-free hair that’s not just really fun to look at, but healthy, too. For six glorious, glorious weeks. Oh, what’s that? You want all the above and then some other stuff, too? No problem.

Gussi’s an innovative keratin-based smoothing treatment that leaves hair smoother, shinier and healthier than before. And, unlike many in-salon treatments, Gussi ditches the formaldehyde—a carcinogen that, if you can believe it, is found in most popular straighteners.

FORMALDEHYDE-FREE FOR YOU AND ME

We’re proud to say no and absolutely no to formaldehyde, which is a common ingredient in a lot of beauty brands, especially smoothing treatments.

Why do we do without it? Because formaldehyde can be extremely damaging, releasing harmful toxic gas into the air you breathe and even into your skin—making the choice not just risky for you, but pets and kiddos, too. Yikes. So, our decision to swap out formaldehydes and other harmful chemicals for Gussi’s unique frizz-fighting formulation is a rare, but sincere and conscious choice that leaves your locks feeling even smoother, silkier, and stronger for up to six weeks. Because we wouldn’t want you putting anything on your pretty little heads that we wouldn’t put on ours.

STUFF’S GOT SCRUPLES

Parabens, phthalates or formaldehydes?

Ew, never. Gussi is made with ingredients that have standards as high as yours, is gentle on hair and never tested on animals.
