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 smoothing treatments.
Why do we do without it?
Because formaldehydes can be extremely dangerous, releasing harmful toxic gas into the air you breathe and even into your skin - making this ingredient not just risky for you, but for pets and kiddos, too. Yikes.
We wanted Gussi to have standards as high as yours. So we swapped out formaldehydes and other harmful chemicals in favor of a safe, clean and powerful unique frizz-fighting formulation that’s gentle on hair and never tested on animals. You’ll look great with hair that’s smoother, silkier and stronger - and you’ll feel great about it, too.
