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.

Soft and shiny!

I love this product. Started using during pandemic and never stopped. Question is there a restriction on hair coloring before of after Gussi (i.e. waiting a week before or after?)

Better than salon

The bundle was enough for 2 complete treatments for me. I have shoulder-glad length thick but fine hair. I liked it better than professional keratin treatments that cost close to $500. Gussi left my hair with way more body than the salon treatment. It is very easy to do at home (much faster than salon) but will really only last about 4 weeks. Your hair will smell weird for several days but it’s still worth it for me. I also purchased the shampoo and conditioner and I think that is a must. If you are going to buy they treatment why not prolong it with the shampoo and conditioner? My first order was a one-time purchase but I just signed up for the subscription.

One product = the only way I could grow my hair out. Top notch and gentle enough for me to use each month. I also have a lot of allergies but I have no reactions to this. Highly recommend

Love it!

I love this product for my child with 4a4b super dense 24 inch hair. We straighten every Christmas and the bundle made it so much easier and faster. Her hair is hydrated, shiny, and after three days there’s no reversion. I will be repurchasing!

Love to hear that Gussi Bundle has made her hair healthy, hydrated, and shiny! Thank you for your kind feedback. We appreciate you!

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!
