how to

Salon-level results, at-home ease

Step 1


Wash your hair twice with Squeaky Clean Priming Shampoo to make sure it’s clean. Do not condition at this time. Towel dry.

Step 2


Section hair into four parts, shake Smooth Operator Keratin Treatment well, then spray each section, root to tip, taking care not to get any in your eyes. Comb through each section —you should see tiny foamy bubbles in the teeth of the comb as you do this part, indicating you’ve got enough product. We’ve designed Gussi to slightly foam to indicate the saturation level, so you’ll know where you’ve already applied and where you need more to even it out. Repeat with each section of hair. Have that comb ready, though, the foaming happens quickly.

Saturate hair completely.

After you’ve applied the keratin treatment, gather all four sections of your hair and comb through, double-checking that the product is applied evenly. After you’ve applied the keratin treatment, comb through all four sections and let process for 20 minutes.

Hot tips:

  • You’ll likely need 15 or more sprays for each of the four sections of hair; for hair longer than shoulder length, expect to finish the Gussi bottle with one application
  • Spritz treatment 6-8” away from hair
  • Keep product away from your eyes and be careful not to get the treatment on your clothing

Step 3


When 20 minutes are up, hop in the shower and lightly rinse your hair with only water (don’t use shampoo in this step)—don’t overdo it, there should still be a small amount of treatment left in your strands after the rinse. If you’ve got longer hair, a good rule of thumb is to hold the ends of your hair up, closer to your head, so the treatment doesn’t run down your back. You’ll want your hair to feel as if there’s a little slickness to it, similar to how it feels after you’ve applied a leave-in conditioner. A good indicator of having enough product on your hair is being able to run your fingers through it without any tangles.

Hot tips:

  • Rinse hair with warm water
  • Do not shampoo at this time

Step 4


Towel dry and blow dry your hair completely using a brush to smooth it out.

Step 5


Comb through your hair, then use a ceramic or titanium flatiron in 1” sections to lock in the treatment. This may require a few flatiron passes for each 1" section to get the smooth result you want. Note: this step is necessary to lock in the treatment. It will not permanently straighten hair - your wave or curls will return (minus the frizz!) if you air dry or dry with a diffuser after your next wash.

Start with your flatiron temperature at 380° and expect smooth results after 3-4 passes per 1” section. If you need more than 4 passes per section, increase temperature to 390°—but never exceed a max temperature of 400°.

Hot tips:

  • The lower you can keep the temperature of the flatiron and still get the desired results, the better it’ll be for the health of your hair.
