Gussi is a keratin smoothing treatment just like you’d get in a salon, only at home and for less time and money. We're specially formulated to make hair shiny, smooth, and frizz-free for up to six weeks. Gussi is committed to using clean, non-toxic ingredients that help make your hair healthier while also looking flawless. Gussi is 100% formaldehyde-free, paraben-free, and phthalate-free, instead packed with hair-loving ingredients like keratin, moringa seed oil, soy protein and vitamins.
