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 :)"

Will a gloss damage my hair?

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.

Amazing!!

I started following Abbey Yung who got me into hair glossing! The deep dive into glosses brought me here and wow. This gloss is my favorite out of all the others i’ve tried. It left my hair SO shiny and SO silky. Definitely will be reordering

This is like purple shampoo on steroids!

If you struggle with your hair getting yellow in between salon visits this is my new favorite product! I have really bright blonde hair and leave this on for 5-7 minutes in the shower and it gets rid of all the yellow for WEEKS! Obsessed with this stuff!
