Kristin Ess Hair Copper + Auburn Hair Gloss Semi Permanent Hair Dye - Copper Penny - Shine Boosting Red, Auburn + Strawberry Blonde Color - Deep Conditioning Brightening Treatment for Women - Vegan

This gloss makes my hair feel like I just left the salon. It adds such a rich tone and insane shine without damaging or drying my ends — my hair literally glows in the light. The color isn’t overly dark or flat — it gives that natural, deep brown look with dimension. The process is super easy and the formula doesn’t have that harsh chemical smell most dyes do. My hair feels softer afterward — like freshly conditioned soft — and it even smells like I just came from the salon (in a good way). It did stain my shower because I applied it in my shower, but I’ve seen some people apply it outside of the shower so I’ll try that next time. I honestly don’t even have to get my hair done professionally anymore. Definitely one of those products that actually does what it says — glossy, soft, rich color that lasts.

I’ve purchased the Kristin Ess Hair Gloss in Chocolate Cosmo Dark Golden Brown three times since October 2025, and I honestly don’t see myself stopping anytime soon. Forget paying $300 and spending hours in a salon chair—this takes under 30 minutes at home and delivers beautiful results. It leaves my hair incredibly shiny, smooth, and healthy-looking, like I just walked out of a professional gloss appointment. The color refresh is subtle but noticeable, perfect for reviving dull or faded hair without commitment. Important to note: this does not cover grays, but that’s not what I use it for. As a gloss and tone refresher, it’s amazing. If you want salon-quality shine without the salon price or time commitment, this is 100% worth it. 💇🏽‍♀️✨

I have brunette hair on the dark side of medium brown. I had been getting it professionally dyed but regular salon visits just aren’t in the budget right now so I picked this up after reviews on TikTok. I got Bittersweet Dark Brunette as it’s about the salon color I get. There are gloves in the box and the two bottles mixed easily enough. I’d recommend swirling instead of vigorously shaking it, let it sit for a minute then give it a gentle shake again as the product gets thicker as it mixes. I washed my hair with a clarifying shampoo first to get any product and build up out of my hair and rinsed throughly, rough towel dried my hair then applied the product. It applied easily enough and the smell wasn’t super strong but not overly pleasant (smelled mildly of wet dog). I let it sit on my hair for about 30 minutes then washed it out with Kristen Ess shampoo and conditioner. I got it EVERYWHERE on my skin and it washed right off but where I touched my shower with a dye covered hand did stain my shower. Rinsing didn’t stain my shower and it didn’t have any bleed out on the towel afterward. I used very tepid water to rinse it and wash my hair. It covered grays and previously lightened areas and it left my hair soft. I put a random leave in conditioner in afterward as a precaution since other reviews said it made their hair dry. I will probably do a hair mask before my next wash too. One bottle was more than enough to get all of my fine, thick, mid back length hair. I would absolutely use this again.

I recently tried the Kristin Ess Signature Hair Gloss, and overall, it delivered on its promise of brightening and toning my hair with just one application. As someone with tight spiral curls, achieving the right balance of tone and vibrancy is crucial for me, and this product did make a noticeable difference in that regard. The application process was straightforward, and I appreciated the convenience of achieving salon-like results at home. The toning effect was visible, and it added a beautiful shine to my curls. However, I did notice that my hair felt a bit dry after using the gloss. Being blessed with tight spiral curls means that my hair tends to be on the drier side naturally, and unfortunately, the gloss seemed to amplify this dryness. While I appreciate the toning benefits, the dryness was a concern for me. To combat this, I followed up with a deep conditioning treatment, which helped restore moisture to my curls. The fragrance of the gloss is not overpowering, and it didn't linger for an extended period. The results were noticeable, and my curls had a more polished and refined appearance. If you have a reliable moisturizing routine for your curls, this product could be a great addition for achieving that salon-fresh look. In summary, the Kristin Ess Signature Hair Gloss is effective in toning and brightening hair, but individuals with naturally dry or curly hair may want to be cautious and follow up with a hydrating treatment. It's a product with potential, and with the right hair care routine, it can enhance the overall vibrancy of your hair color.

Easy to use and leaves a beautiful shine, with no damage to the hair. Definitely, I must buy it again.

Love this stuff! My hair was naturally similar to this colour to this but it’s been going grey and dull. I followed the directions exactly and left it one the least amount of time suggested. It was more orange than I expected but after one extra wash I love it! The package states it does not cover gray, but it did cover all of mine. I hope they keep making it! My hair doesn't seem dry or damaged at all, it feels great!

Fantastic stuff, brings back the vibrancy to my auburn hair now I am getting a little older.

it’s alright as a hair dye i guess but it didn’t really do much to my hair colour- but got some fun seeing my hair auburn. for a few days. but to be fair i had dark blonde hair before using it i noticed i lost a bit of hair after using it but that could just be stress from life - or me constantly fixing my hair parting . also if you’re in the uk it’s shipped from america, so takes a long time to be delivered. And you can only use this dye once , as you need to mix two bottles together and once the chemical reaction happens you can’t reuse it. plus you only use like a quarter or half of the dye so it’s really expensive but it was hard to find other auburn hair dyes, so it’s alright i guess. if was cheaper and shipped from uk i’d give it a 4 star rating

Unfortunately this product did not change the colour or tone of my hair. I was expecting it to cancel out the brassy tones and be overall a darker shade of brown but it almost looks more red than before. What a waste and it wasnt cheap. I paid almost $60 for this product.
