Description

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.

How To Use
  1. 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.

  2. Apply Smooth Operator Keratin Treatment, comb thru and let process for ~20-30 minutes.

  3. Rinse your hair with water and towel dry.

  4. Blow dry smooth until hair is completely dry.

  5. 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.

It delivered on its promises but the scent is a no

As a first-time user of the At-Home Keratin Treatment Kit and the brand alone, I was pleasantly surprised by the results. My very dry, damaged, and color-processed hair has been craving some TLC for a while now, and this kit delivered for a fraction of what the salon I frequent was charging. The process was easy/straightforward, and only took about an hour from start to finish. What I will say though is that the fragrance of the product left a lot to be desired. I just didn’t like the scent and how long it lasted in my hair. Following the treatment, my hair did feel noticeably softer and frizz-free though which is what I wanted. I also take great comfort in knowing that this is a clean, non-toxic formula. If they changed the fragrance I’d definitely be reaching for this kit again. This was gifted by gussihair.

Product was gifted by gussihair to write this review. After 1 use, my hair felt clean and shinier than before. At first the shampoo made my hair rough but it made sense because that’s what happens with clean hair. After the keratin treatment, I was obsessed!

Hi!

Gussi is committed to using clean ingredients! We greatly appreciate your five-star rating. It’s fantastic to know that you had a wonderful experience with us.

Amazing!

I have never used a keratin treatment before since I didn’t know about this amazing at-home treatment kit! This only took me about an hour from first rinse to straightening, and it was a super easy application. My hair has never looked so sleek and shiny! I suffer a lot from frizz and this has helped tremendously, absolutely worth it since it lasts through so many washes! My hair is so hydrated and soft, I could not recommend this more! Kindly gifted by Gussi.

Hi Devon!

So smooth!

I’ve never had a keratin treatment before, but I was really impressed by this one! My hair looks so smooth and it really got rid of a lot of frizz. You have to blow dry and straighten your hair when doing the application, so I’m excited to see what my naturally wavy hair looks like after I wash it! This was offered by gussihair for review

Hi!

We are confident you will love the way your natural wavy hair looks like after first wash. Our treatment does not break the bonds of the hair, allowing you to keep your natural texture without the frizz.

Thanks so much for sharing your experience with us.

FAQ

What is keratin and is keratin good for hair?

Keratin is a protein naturally made in the body that makes up your hair, skin, and nails - so yes, keratin is great for your hair! Our formaldehyde free keratin treatment adds an extra powerful dose of non-toxic keratin that will help your hair become softer, smoother, and less prone to frizz. Our At-Home Keratin Treatment works great with all hair types and lasts up to six weeks from just one treatment!


Is keratin good for hair with low porosity, high porosity or normal hair types?

Simple answer, all of the above! Keratin is great for all hair types, however sometimes one’s hair type isn’t able to properly absorb the protein to be able to gain the best results. Our at-home keratin treatment uses hydrolyzed keratin which is a broken down version of the larger protein, allowing for even hair with low porosity to reap the benefits. Hydrolyzed keratin works wonders even if you have damaged hair, since the hydrolyzed keratin would fill in the gaps in the hair strands that have been weakened over time. Gussi is also NOT a chemical straightener or relaxer, so it won’t disturb any of your natural curl patterns. This is just another example of how Gussi has the best keratin treatment kit.


Is it easy to do a keratin treatment at home?

We have made it extremely easy! Salon keratin treatments are often expensive, have a long processing time and use products that do more harm than good. Salon keratin treatments usually involve the use of formaldehyde, which leads to a range of negative side effects on your hair and health as stated by the FDA. This is why we developed the best formaldehyde-free formula so that you can do your keratin treatment at home with peace of mind that you and your hair are in good hands. To complete our powerful frizz-fighting treatment, you only need an hour of your time and some home essentials like a towel, hair clips, plastic comb, brush, blow dryer, and flat iron. It’s five simple steps to six weeks of great hair, all from just one treatment!
