The first at-home keratin hair treatment! This innovative DIY smoothing solution leaves hair frizz-free for weeks on end, plus shinier, healthier, and more manageable than before. Unlike many in-salon keratin treatments, Gussi ditches the formaldehyde and all other nasty chemicals. Fabulously sleek hair that lasts, all from the comfort of your own bathroom.
For all hair types. Results may vary slightly based on hair texture, coarseness, porosity, and overall hair condition.
Color-safe. For best results, Gussi up prior to coloring hair. You can color your hair immediately after completing the Gussi treatment. If you recently colored your hair, wait at least five washes before applying Gussi's formaldehyde free treatment.
Keep those curls - if you want! Gussi won’t break the bonds of your hair, so your natural texture remains – just with a smoother, more manageable, elongated pattern for the duration of the treatment.You must flat iron hair as the final step to lock in the treatment, but you can then immediately rinse to get those gorg curls back.
Wash 2x with Squeaky Clean Priming Shampoo to clarify and prep your hair. If you have very dry or damaged hair, just 1 wash will do it.
Apply Smooth Operator Keratin Treatment, comb thru and let process for ~20 minutes.
Rinse your hair with water and towel dry.
Blow dry smooth until hair is completely dry.
Flat iron hair in small sections to activate the frizz-fighting power.
Style however you like! Immediately following your DIY keratin treatment, you’re free to wash, color, heat style, curl your hair and even work out – whatever you and your hair desire.

I did exactly what it says in the instructions and my hair is really super straight without frizz. And the best thing is that I can dye it without altering the results. Without mention that it last 5 weeks, i do recommend this keratin kit treatment. Gifted by Gussi hair
Gussi won’t break the bonds of your hair and it doesn’t permanently straighten hair. Instead, the Gussi treatment makes hair smoother, easier to manage, and faster to blow-dry. You can color your hair immediately following the treatment. Thanks so much for sharing your experience with us.
I received this product complimentary from Gussi Hair in exchange for my honest review. When I received my bottles they were only halfway filled with product. Not sure if that’s normal but it didn’t look like they had leaked. I used it per the instructions and my hair did feel smooth and frizz free after using. I wasn't crazy about the scent while using but didn’t really notice it after my hair dried.
Yes, bottles are not filled for shaking reasons before you apply. Smell is natural byproduct of keratin and will be minimized or eliminated when hair is dry. Happy to hear that your frizz has been tamed. Thank you!
It is one of the best in home keratin treatment I have worked with. It makes the hair shiny, smooth and healthy without damaging. Also it is very good because it works upto 6 weeks. I am impressed with the results. Gifted by gussi hair
