How to Use Your Gloss

A simple 3-step ritual to refresh and fine-tune your color at home.

Step 1: Mix Thoroughly

Pour your color into the Developer bottle and shake well until fully blended. You want it smooth, seamless, and fully blended before applying.

Step 2: Apply Evenly

Apply to clean, damp hair, working evenly from roots to ends. Take your time — full saturation is what gives you that polished, intentional finish.

Step 3: Process + Rinse

Let it sit for 7–15 minutes depending on your shade and how rich you want to go. Rinse thoroughly and style as usual to reveal refreshed, glossy color.

Real Results. Real Gloss.

"This product is amazing (like everything nous does)! It makes my hair feel so soft and shiny and it's really easy to use. It allows me to go longer in between balayage sessions by toning any brassiness. I try to use about every six weeks, and every time I use this product people ask me if I just got fresh highlights. It's that good! Simply obsessed"

N.05 LET'S BE CLEAR

"My highlights were getting that Carmel over golden blonde tone and I was recommended this last year, it’s magical! I’ve used it probably 4-5 times since! Love it so much, haven’t gotten my hair done in a while using thing gives it that extra toning boost. For myself it turned the brassy to pretty brown tones, like coffee for your hair! Totally recommend :)"

FAQs

How often should I use a gloss?

Will a gloss damage my hair?
No, our glosses are formulated with ingredients that will always make your hair feel better and not worse! 
Can I use a gloss on non- color treated hair?
Yes, consider a gloss like a top coat for your hair, it will not permanently change your hair color, just add a sheen on top. We have four pigmented shades that will enhance the color you have or if you just want the shine benefits, our clear gloss is a perfect option.
How long does the gloss last?
4-6 weeks or 20 washes.
How do I know what color is right for me?

N.01 is the best for brassy hair!

I have always tried to combat the yellow my hair gets after leaving the salon with purple shampoo, but it is always so drying and can sometimes make it look dingey! I LOVE this product, I use it for 5 minutes after I shampoo and I swear its like going to the salon to get a toner!! My hair feels so shiny and it completely gets rid of the brassiness! I will be a forever customer!

Best hair I’ve had!

I usually use head and shoulders as my hair gets so greasy throughout the day and I end up a bit of a greaseball! I found Nous on Revolve and decided to give their shampoo and conditioner a try and It’s made the biggest change in my hair. I can actually use the conditioner and still have my feeling hair light and soft without it being greasy. Absolutely would recommend for anyone with greasy hair, it’s the only product I’ve found to really help!

My scalp burns so easy in the sun and this has been the perfect solution that doesn’t grease my hair up. I love how compact it is and take it everywhere with me in my everyday day bag, 10/10 recommend!

Gloss #1

I used this gloss to refresh my blonde in between appointments and it has been my saving grace! It helped blend my grow out to my highlights and even out the different shades from my grow out.
