Keratin-based products are haircare products infused with keratin protein and other hair-nourishing ingredients. Keratin is a protein naturally made in the body that makes up your hair, skin, and nails. What does keratin do to your hair? It turns your #HairGoals into reality by making your hair more smooth, shiny, and frizz-free. Keratin even helps to repair damaged hair and split ends! So silky, you won’t be able to keep your hands off it.

Gussi’s keratin treatment products, of course! Our products are all formaldehyde-free and super easy to use.  Our all-star at-home keratin treatment kit is done at home, in the comfort of your own bathroom,  in only 5 simple steps. The kit comes with a Priming Shampoo to prep your hair for the Keratin Treatment Spray. This combo will smooth frizz, nourish hair, repair split ends, cut blow-dry time by ~30%, and improve overall hair health. After only about an hour #gussiUP,, this at-home treatment will give you long-lasting results for up to six weeks!

Totally safe! What tends to make keratin products harmful are the extra chemicals like formaldehyde. When going to the salon to get a keratin hair treatment, the products often contain formaldehyde which can do more harm than good. Formaldehyde can irritate the skin, eyes, nose, and throat when breathed in. Gussi’s keratin products are completely formaldehyde-free, clean and safe, and you don’t even have to go to a salon to use them! On top of that, we have made it super easy  for you to get beautiful frizz-free hair in the comfort of your own home. Our products were formulated to not just make hair shiny, smooth, and frizz-free for up to six weeks, but also to help make hair healthier in the process. Because just like you, we love to have it all.

Our clean ingredients allow the results to speak for themselves! Formulated without harsh chemicals like formaldehyde, Gussi is instead formulated with beneficial proteins and vitamins. Your hair will thank you after you try our keratin products. What else is so great, you ask? After applying our at-home keratin treatment, you don't need to worry about having a bad hair day for up to six weeks. You can even prolong your results with our maintenance shampoo and conditioner.
