Oh...glad you asked
Gussi is a keratin treatment just like you’d get in a salon, only at-home and for less time and money. Specially formulated to not just make hair shiny, smooth and frizz-free, it’s designed with ingredients that actually help make hair healthier and is 100% formaldehyde-free.
The treatment is easy and quick, only taking about 20 minutes to process as opposed to hours, and lasts for up to six weeks.
Plus, Gussi gives you the freedom to wear your hair how you want, whenever you want—all while keeping the healthy shine. Hair can be curled, braided, put up in a ponytail, or kept straight immediately following the treatment. No waiting, no compromising.
They are indeed. All Gussi products are free of formaldehyde, parabens, methylene glycol, and phthalates. We’ve also earned PETA’s seal of approval, are cruelty-free, and do absolutely no animal testing. Oh, and bonus: our Protection Plan Upkeep Shampoos and Conditioners are sulfate-free, too.
Formaldehyde is a common ingredient in a lot of keratin treatments used today, but Gussi made the choice to formulate our smoothing treatment without it because, frankly, it’s better and safer. If there’s formaldehyde in a product, even after it’s rinsed out, harmful toxins are released into your hair, skin and throughout your home—especially after heat is applied. Worse yet, you can breathe these toxic fumes into your lungs once they’ve been emitted into the air. Not great, right?
A lot of countries and states are ruling out the ingredient altogether, and we wanted to stand ahead of the pack here in the U.S. and launch a product we could feel good about giving people. Not just when it comes to results, but ethics, too.
If you have any allergies or skin sensitivity, we always recommend a patch test on your arm, waiting 15 minutes to ensure no reaction. While our ingredients are safe for topical use, if you have any health conditions we suggest consulting your physician before use.
Sulfates are required as a one-time, pre-treatment step to open the hair cuticle so that it accepts the Gussi treatment, allowing it to truly penetrate the hair shaft. Gussi’s Squeaky Clean Priming Shampoo has been designed with a pH level equal to water and slightly higher than that of hair, making it far less damaging than other similar priming shampoos. Our aftercare shampoo and conditioner that we recommend for ongoing use are entirely free of sulfates, phthalates, and parabens.
At Gussi we don’t believe you should have to risk your health to get beautiful hair. We’ve developed a highly effective formulation based on natural ingredients like silkworm and sheep’s wool proteins and vitamins that fortify the hair while smoothing it powerfully, yet naturally. Gussi is not a chemical relaxer, but it effectively penetrates the hair without damaging it, leaving it healthier than before.
In most cases, one, though that may depend on the length and thickness of your hair. If you have short or very fine hair, you may be able to use the product twice. When you apply the keratin treatment, you want hair to be fully saturated, root to tip, which is why most will get one full application from the treatment.
Yes, Gussi can be used on all hair types, but results may vary according to number of factors, like the type of hair you have, the texture, coarseness, porosity (which is fancy speak for your hair’s ability to absorb moisture), as well as its overall condition and health.
Yes. If you’re in the mood to color your hair or already have an appointment booked, go ahead. You can color your hair immediately following your Gussi treatment.
If you’ve very recently colored your hair, you may experience a slight color shift after using Gussi — brightening and refreshing blondes or lifting artificial color for darker hues. Reduce the temperature of your flatiron to 360° to prevent heat damage.
Henna and progressive hair color may contain metallic salts like copper, silver, lead, and magnesium. These metallic salts can eventually build up on the hair causing adverse results; dry, damaged, dull, or brittle. If the hair has been treated with an at home henna, it is recommended to remove the henna from the hair prior to a Gussi treatment.
If you’ve recently used another chemical straightening treatment, we recommend giving your hair a break and waiting at least two weeks before using Gussi.
Definitely, and it’ll nourish hair and leave it in better condition than it was prior to the treatment. Repeated application of Gussi treatments over time will restore the hair’s health and condition, repairing damage from prior chemical services such as coloring, bleaching, relaxing or formaldehyde-based treatments. In fact, if you use Gussi repetitively, results improve and the treatment will last longer each time it is used. The product has been proven to have the same pH as lemon juice, so it lifts the cuticle only a small amount, allowing nature-derived ingredients to penetrate hair without incurring damage. Gussi also strengthens thin hair that is experiencing breakage, strengthening it with botanicals so that it can grow longer, stronger and thicker.
Absolutely not. Part of what makes Gussi, Gussi is that you get to choose how you style your hair. Our products are formulated to never break the bonds of the hair, which means your curly hair can come back whenever you like, but the curl will be more elongated for the duration of your treatment. If you want a super sleek appearance, flatiron your hair for a smooth as glass look. Or, if you want to show off some curl, just use a diffuser when you blowdry or air dry to get some of your natural curl pattern back, but it will be more elongated and shiny. So, for the entire six weeks of your treatment, you’re never locked into one look—you’ve got nothing but pretty possibilities ahead.
We’ve formulated to stand up to the elements, so even if it’s humid or rainy, your treatment results are proven to hold up.
Gussi is formulated without formaldehydes or dangerous chemicals, though, to be extra safe, we always recommend double-checking with your physician for a professional recommendation before you begin your smoothing treatment.
One of the key ingredients in Gussi is the keratin protein, which is naturally-derived (fun fact: it actually comes from sheep’s wool that needs to be shaved off of them). It’s a safe and effective ingredient, may leave behind a slight fragrance on the hair. The good news is that this is normal and temporary—if you experience this, the smell will go away after the hair is completely dry. And, usually, after 2-3 shampoos, the scent is gone for the remainder of the treatment.
You’ll see results immediately after doing your treatment—just 20 minutes for the application, plus some time to prep and style.
The results last for six weeks, but if you love your look, we recommend placing an order again after four weeks to make sure you’ve got Gussi on-hand and ready to go for your next application. Or, to make things extra easy and convenient, subscribe and we’ll automatically send Gussi to your doorstep before you need your next application, saving you hassle and extra moolah.
Take good care of your hair and use a sulfate-free shampoo, like Gussi's Protection Plan. Results will begin to gradually fade over the course of weeks, eventually washing out completely (without leaving a harsh demarcation)—but healthier hair is able to hold onto smoothness and shine longer.
Making morning routines easier and faster, Gussi cuts blowdry time by 30% after one treatment.
Believe it or not, you don’t have to wait! You can tie your hair up, shower, style, sweat and live your life immediately after the treatment is locked with a flatiron! Gussi is here to make your life easier so no need to wait, resume your regular routine and enjoy your new frizz-free hair!
We recommend starting with your flatiron temperature at 380 degrees—at this temperature, your hair should be smooth and shiny within 3-4 passes. If your hair requires more than four passes, you may need to increase the temperature to 390 degrees, but to keep your hair damage-free and healthy, never exceed a max temperature of 400 degrees.
After you’ve applied the keratin treatment, you’ll want to give your hair a light, casual rinse, but don’t get rid of the product entirely. You’ll want to use only water and skip the shampoo; your hair should still have a little bit of slipperiness to it (similar to what you’d expect from a leave-in conditioner), this will help indicate that you’ve got enough product still on your strands. The keratin treatment itself is really the magic of the whole thing. By being careful not to over-rinse, this ensures there’s still enough product on the hair to do its thing when you lock in your look.
As soon as you place your order, we’ll start processing it to get it on its way to you. This usually takes about a day or two and we’ll send you an email when your package has officially shipped.
