Hair Gloss Treatments Are Exploding in Popularity – The “Expensive Hair” Trend Goes Mainstream

By Runway Magazine Editorial Team | June 17, 2026

If 2025 was all about glass skin, 2026 is the year of glass hair. Hair is following the same logic as skin. The shift from foundation-covered perfection has its parallel in hair: the movement away from frequent chemical coloring and toward investment in making existing hair look like the most expensive version of itself. Glass hair has moved from red carpet close-ups to TikTok feeds to salon appointment books. The vehicle driving all of it is the hair gloss treatment.

The hair gloss market reflects the scale of this shift. Valued at $6.29 billion in 2024, it is projected to reach $8.38 billion by 2031 at a 4.2% compound annual growth rate. 55% of salon clients now opt for gloss as part of their haircare regimen. Over 45% of regular beauty users view gloss as an essential service. These are not the numbers of a niche trend. They describe a mainstream category in the middle of a major growth cycle.

What the “Expensive Hair” Aesthetic Actually Means

The term “expensive hair” has become one of 2026’s most searched beauty concepts, but the definition is counterintuitive. Expensive hair has nothing to do with how much you spend at the salon. It describes a quality of light — a texture that signals health so profound it borders on luxurious. Think of the way light glances off a silk scarf. That quality of light is expensive hair. Hair this hydrated, smooth, and structurally sound catches light like a mirror rather than absorbing it like cotton.

This aesthetic focuses on what your hair communicates about its internal condition rather than any external modification. Heavy highlighting, frequent color services, and dramatic transformations have given way to a different priority. Hair that looks undeniably, unmistakably healthy. A sleek shiny hair finish that reads as the result of excellent genetics rather than salon intervention is the endpoint. The driving logic of this moment is not about spending more on color. It is about redirecting that spend toward treatments that optimize the hair you already have.

Colorist Jeremy Cohen, of IGK Salon, captures the logic precisely. A gloss, he says, is “the topcoat of hair color. It enhances shine, refines tone, softens harsh lines, and makes color look more expensive without a full color service.” The topcoat analogy is perfect. Just as a clear topcoat transforms the finish of a nail, this treatment transforms the finish of hair. It seals the cuticle, reflects light, and delivers an immediate result that looks like health rather than effort.

Hair Gloss vs. Hair Glaze: What Is the Difference?

The hair glaze vs gloss distinction matters because the two treatments accomplish different things. Choosing the wrong one is the most common mistake people make when entering this category.

Hair.com’s expert guide to gloss vs. glaze confirms: a hair gloss is demi-permanent. It works through the cuticle layer to deposit tint while acidifying the hair shaft. The result: a closed cuticle and a glassy, light-reflective surface. Glosses shift color tone, neutralize brassiness, blend grown-out roots, and significantly boost shine. Applied in a salon in about 20 minutes, they last four to eight weeks. Redken Shades EQ is the professional benchmark: an acidic, ammonia-free formula that combines oxidative and direct dyes. Tracey Cunningham, Redken’s celebrity colorist: “They are not permanent and will gradually fade over a few weeks. Great if you want to try different colors without totally committing.” Even a clear gloss — with no pigment at all — delivers the cuticle-sealing, shine-amplifying result that defines the expensive hair aesthetic.

A hair glaze sits on top of the hair rather than penetrating the cuticle. It coats the surface, reduces frizz, and adds immediate shine. Glazes are velvety and slightly more opaque than a gloss. Their effect is dramatic and instant. TikTok’s “Glaze Craze” describes the immediate liquid-hair reveal that follows a glaze application. That effect is also more temporary than a gloss. Glazes last two to four weeks and fade more quickly. The choice depends on your goal. Color toning and longer-lasting shine call for a gloss. Immediate surface smoothness and frizz control call for a glaze.

Salon Demand and the Semi-Permanent Hair Gloss Moment

Semi permanent hair gloss has become one of the most-requested salon add-on services of 2026. Stylists describe this salon shine treatment as a non-negotiable final step. Clients want that “just stepped out of a luxury salon” finish without committing to a full color service. The hair shine treatment salon demand surge connects directly to this aesthetic. Clients who once booked full-color appointments every six to eight weeks are now extending intervals and booking glossing appointments instead.

This shifts the commercial structure of salon services meaningfully. A glossy brunette hair result that once required a demi-permanent color service can now come from a 20-minute gloss add-on. Blonde clients use regular gloss appointments to maintain the “expensive blonde” aesthetic between lightening sessions. Perfectly toned, refined, and healthy. Brunettes benefit from clear or color-matched glosses that amplify depth and make brown hair look rich rather than flat. Any hair type sees an immediate smooth hair treatment effect from a gloss. Parade’s 2026 roundup of the best hair gloss treatments quotes Jeremy Cohen: “When your hair feels dull or flat, a gloss brings it back to life.” That statement describes why the salon demand is sustaining: it is a reliable, low-risk service with a consistent, noticeable result.

At-Home Hair Gloss: How TikTok Made the Category Mainstream

The at home hair gloss category has exploded on TikTok and Amazon beauty rankings in 2026. The viral hair routine follows simple logic. Use a salon-quality gloss between appointments to maintain the “expensive hair” finish without the salon visit cost.

Kristin Ess Hair Gloss is the most-discussed at-home gloss on TikTok. It is a silicone-free, ammonia-free, semi-permanent in-shower treatment that lasts three to four weeks. Creators post results: “I tried the at-home viral #hairgloss from Kristin Ess and I AM SOLD.” The format addresses a real gap: the period between salon visits when color goes flat and hair loses its glass-hair luster.

High shine hair products also include CÉCRED’s Heat Activated Silk Glaze, designed to deliver silk-glazed results during blowout styling. OLAPLEX No. 8 Bond Intense Moisture Mask serves as a preparatory step. It repairs bond damage before a gloss so the cuticle can seal properly and reflect light at full capacity. Madison Beer’s widely shared beauty hack — glossing instead of dyeing to refresh brunette depth — helped normalize the category.

TikTok hair trends have translated a salon concept — the topcoat gloss — into accessible at-home language: the “liquid hair” effect. Smooth cuticles reflect light better. Lowering pH, balancing the hair shaft after washing, and coating with conditioning agents creates them. At-home glosses deliver all three in one step — which is why they work.

Building a High-Shine Hair Routine

The glass hair look tutorial framework that professional stylists consistently recommend starts before the gloss. Damaged, porous, or over-processed hair will not reflect light efficiently no matter what is applied to the surface. Any shiny hair routine starts here: bond repair through OLAPLEX or CÉCRED creates the structural foundation. Once the hair fiber is healthy, a gloss or glaze seals the cuticle. The mirror-like surface that defines the glass hair trend 2026 follows.

Healthy hair shine tips from colorists: reduce heat styling, use acidic rinse-out conditioners, apply a lightweight leave-in, and gloss every four to six weeks. Best hair gloss products — Kristin Ess, Redken Shades EQ, CÉCRED’s silk glaze — combine tint or conditioning agents with pH-adjusting formulas that close the cuticle after application.

The frizz control hair gloss effect drives repeat purchase even for clients who were not primarily seeking color services. Sealed cuticles mean smoother strands, which means less friction, less frizz, and less moisture loss between washes. That ultra-reflective finish that reads on camera as expensive is now available at the drugstore, the salon, and on TikTok alike. In 2026, that combination of accessibility, visual impact, and social shareability has made glossing the beauty service of the year.
