You know that feeling when you walk out of a salon and your hair catches the light in a way that feels almost illegal? It’s not just the cut. It’s the shine. Most of us try to recreate that at home with a box of permanent dye from the drugstore, but we usually end up with a flat, "inked-on" look that lacks any sort of dimension. Honestly, it’s frustrating. That’s exactly where Kristin Ess Hair Gloss fits into the equation, and it’s probably the most misunderstood product in the aisle.
It isn't a dye. Not really.
If you go into this thinking you’re going to turn your dark brunette hair into a honey blonde, you’re going to be disappointed. That’s just not how chemistry works. This is a demi-permanent treatment meant to tone, shine, and refresh. It bridges the gap between those expensive six-week salon visits. Kristin Ess, the celebrity stylist who founded the brand, basically built her reputation on "expensive-looking hair," and this Signature Gloss Collection is her attempt to bottle that specific finish for about fifteen bucks.
What Actually Happens When You Put Kristin Ess Hair Gloss in Your Hair?
Let’s talk science for a second, but keep it simple. Permanent hair color opens up the hair cuticle and stays there forever. It’s a commitment. Kristin Ess Hair Gloss, however, is acidic. It doesn't lift your natural pigment. Instead, it lays a sheer veil of color and intense shine over the top of your existing strands. Think of it like a lip gloss for your hair. You can still see what’s underneath, but the tone is shifted and the surface is smoothed down.

When the cuticle is smooth, it reflects light. When it’s ruffled—which happens from heat styling or hard water—it absorbs light. That’s why your hair looks dull. The gloss seals that cuticle.
I’ve seen people complain that it "didn't do anything," but usually, that’s because they chose a shade that was too light. You can't go lighter. You can only go darker, richer, or more neutralized. If you have brassy orange tones in your blonde, you grab a "Winter Wheat" or "Crystal Quartz" to cool it down. If your chocolate brown is looking a bit mousy, "Bittersweet" adds that depth back. It’s subtle. It’s meant to be.
The Application Process is Kinda Messy But Worth It
Don’t wear your favorite white T-shirt. Just don't.
The box comes with two bottles that you mix together. You apply it to wet hair in the shower. This is where people usually mess up: they don't get it everywhere. You really have to massage it in like you’re lathering a shampoo to ensure every single strand is coated. If you miss a spot, it might not be glaringly obvious because it’s a gloss, but you won't get that uniform "glass hair" effect.
Wait 10 to 20 minutes. Kristin Ess herself often suggests the full 20 for maximum deposit.
The smell is... polarizing. It has that signature scent that most of her products have—peonies and musk—but mixed with the chemical reality of a gloss. Some people love it; others find it a bit strong for a small shower stall. Once you rinse it out and follow with a good conditioner, that "new hair" feeling hits. It’s silky. It’s slippery. It feels healthy because the pH of the hair has been brought back down to its happy place.
Real Talk on the Shade Range
There are over a dozen shades, which is actually a lot for a drugstore gloss.
- Crystal Quartz: This is the clear one. If you love your color but hate the dullness, this is your best friend. No pigment, just shine.
- Copper Penny: This is incredibly vibrant. If you aren't ready for a loud, "Look at me" ginger, be careful.
- Smoky Topaz: Perfect for the "expensive brunette" trend. It knocks out those weird reddish-orange tones that pop up when brown hair starts to fade.
- Tortoise: A weirdly named but beautiful warm brown that adds gold reflects.
Why Most People Get It Wrong
The biggest misconception is that this will cover grays. It won't. Not really. It might "stain" them so they look like subtle highlights, but it lacks the ammonia and developer strength to fully saturate a stubborn gray hair. If you have a full head of silver and you want it gone, this isn't the tool.
Another mistake? Using it too often.
Because it’s a demi-permanent, it lasts about 3 to 4 weeks depending on how often you wash your hair. If you use a harsh sulfate shampoo every single day, that gloss is going down the drain in a week. Honestly, use a sulfate-free shampoo. It’s 2026; we should all be doing that anyway if we care about color longevity.
Is It Safe for All Hair Types?
Yes. Because it doesn't contain bleach or high-volume developers, it’s actually quite conditioning. Even if you have curly hair or fine hair, it shouldn't cause damage. In fact, many people with curly hair find it helps with frizz because it lays the cuticle flat. The only caveat is for those with extremely porous, bleached-white hair. If your hair is basically a sponge, it might "grab" the color more intensely than you wanted. If you're platinum and use a dark gloss, it might stick around longer than the promised four weeks.
Let’s Talk About the "Silicones" Controversy
There’s a lot of chatter online about silicones in hair products. Some people avoid them like the plague. Kristin Ess Hair Gloss does use them to achieve that high-shine finish. Here’s the thing: silicones aren't inherently "evil." They provide a protective barrier and reflect light beautifully. However, if you are strictly "Curly Girl Method" compliant, you might want to check the ingredient list. For everyone else, the silicones in this formula are what give you that slippery, salon-quality texture that makes brushing your hair so much easier.
How to Maximize Your Results with Kristin Ess Hair Gloss
If you want the gloss to actually last, you have to prep. Use a clarifying shampoo before you apply the gloss. You want to strip away all the dry shampoo, hairspray, and silicone buildup from your other products so the gloss can actually reach the hair shaft. Don't use a conditioner before the gloss; that just creates a barrier that prevents the color from sticking.
Think of it like painting a wall. You wouldn't paint over a layer of dust, right? You clean it first. Same logic applies here.
- Clarify: Get the junk out.
- Towel Dry: Don't put gloss on soaking wet, dripping hair. It will just slide off. You want it damp, but not "waterfall" wet.
- Saturate: Use the whole bottle if you have long hair. Don't be stingy.
- Heat (Optional but Great): If you really want it to sink in, put on a plastic shower cap and hit it with a blow dryer for five minutes. The warmth opens the cuticle just enough to let more pigment in.
- Rinse Cool: Cold water helps lock that cuticle back down. It’s uncomfortable, but it works.
The Cost-Benefit Reality
Let’s be real. A professional gloss at a high-end salon in a city like New York or Los Angeles can easily cost $80 to $150. Kristin Ess Hair Gloss is roughly $15. Is it as good as a professional Redken Shades EQ treatment applied by a master colorist? No. A professional can mix three different shades to create a custom tone that perfectly matches your skin's undertones.
But for a Tuesday night in your own bathroom? It’s a game-changer. It’s the difference between looking like you haven't had a haircut in six months and looking like you just had a "refresh." It’s a maintenance product.

One thing to watch out for is the "overlap" effect. If you use a dark gloss every single month, the ends of your hair might start to look darker and darker because the color builds up. If you notice your ends getting "inky," skip the gloss on the bottom half of your hair every other time. Only apply it to the top where the fade is most visible.
What to Do Next
If you’re sitting there looking at your hair in the mirror and thinking it looks a bit "blah," here is your roadmap.
First, determine your goal. If you want to fix brassiness, look for a "cool" or "ash" tone. If you want to look sun-kissed, look for "gold" or "warmth." If you just want to look like a shiny version of yourself, get the "Crystal Quartz" clear gloss.
Go to the store and actually look at the back of the box. There’s a chart that shows what the color will look like on different starting levels. Believe the chart. If your hair is black, the blonde gloss will do nothing. If your hair is light blonde, the dark brown gloss will be a permanent life choice for the next few months.
Grab a wide-tooth comb. You’ll need it in the shower to comb the gloss through from roots to ends. This ensures you don't end up with splotchy color. After you rinse, use a deep conditioning mask. While the gloss is conditioning, the process of opening and closing the cuticle can still leave hair feeling like it needs a little extra love.

Skip the heavy heat styling for 24 hours after. Let the hair settle. Let that shine speak for itself. You’ll probably find that you don't even need as much styling cream or oil because the gloss has already done the heavy lifting for you. It’s a low-stakes, high-reward way to feel a bit more put-together without spending three hours in a salon chair.
