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.

My hair normally takes well to keratin / Brazilian blow dry treatments and I was excited to try this given the lower price point. I followed the instructions closely (left the product in a little longer based on other reviews I saw) and my hair was definitely less frizzy when it air dried after the first wash. Sadly wash two saw my hair right back to it’s frizzy poofy self. Would not recommend
Sorry to hear about your post-wash disappointment. Sounds like an application error. The results may vary according to a number of factors, like the type of hair you have, texture, coarseness, the hairs’ ability to absorb moisture, and the overall health and condition of the hair. A member of our customer support team will be in touch asap to help make this right for you.
I like the smoothing effect but I am having so much hair fall out that its not worth it.
There is nothing in the formula to cause the hair to break off. We suggest you consult your physician regarding these concerns. Our customer support team is reaching out directly to help.
The application process was easy. There were no harsh chemical smells but I did have a little burning. The day following the treatment, I exercised and my hair was a little sweaty and a LOT stinky! I kept smelling this awful smell at the gym and later realized it was my hair! My husband confirmed; he said it smelled like a pizza shop, like Parmesan cheese! Yuck! I just washed and conditioned my hair three times with my strongest smelling products and my hair still stinks! I won’t be using it again.
We're so sorry to hear about your experience. Unfortunately, sometimes an odor from the natural keratin can linger if too much product is left in the hair during the rinse step. It shouldn't be there when your hair is dry. Our customer support team is reaching out directly to help.
So I literally followed the instructions to the tee, my hair looked nice at the end, lasted a few days even after the gym and all, but then came was day and my hair was so poofy and frizzy ☹️ so it didn’t work on me.
Sorry to hear that! Please reach out to our team at firstname.lastname@example.org as we'd love to make this right for you and improve your Gussi experience!
I tried a competitor's product first and was very disappointed. But when I tried Gussi I knew that this product was superior. It made my hair very soft and manageable. I can definitely tell that it is helping my hair to stay straight and not get frizzy in the humidity. However, it is not as good as Keratin treatments that I've gotten in salons in the past. I would definitely buy this again if I wasn't able to get to a salon and needed a good frizz-fighting product.
only the good stuff
