After seasons of beachy waves and mermaid-core texture, precision has re-entered the chat. The return of glass hair was spotted earlier this week at London Fashion Week, specifically at the Chet Lo Autumn/Winter 2026 show – and we predict the trend is only going to keep gaining traction. The goal? Hair so shiny it slices through winter air like a freshly sharpened bob.
Backstage, Hair Lead Anna Cofone turned strands into sculptures. "The inspiration for the hair was a reflection of Southeast Asian identity, drawing from the iconic headdresses of Peking Opera," she explains. "In opera, the feathers create these beautiful calligraphic lines that extend the performer's movement." As a result, we were delivered ultra-straight, liquid lengths punctuated by feather accents and tightly constructed chignons.
"The glass-straight hair keeps everything disciplined and refined. It's about control and movement existing together," Anna says. Translation: You can, in fact, have the best of both worlds! Hannah Montana, eat your heart out...
Now, while the runway interpretations lean architectural (partly thanks to their avant-garde fashions), this trend is fully translatable to everyday life. Think sleek ponytails, straightened bobs, or even relaxed lengths. The key? Incorporating hair health into your routine! I'm talking anti-frizz oils, glycolic formulations, and lightweight serums that smooth without weighing hair down.
This trend isn't about frying your ends into submission; it's about nourishment first, polish second!
Your glass hair trend toolkit
The first step to achieving glossy hair is a shine-boosting cleanse. L'Oréal Paris' Elvive Glycolic Gloss Shampoo is formulated with glycolic acid to smooth the hair cuticle and remove dulling buildup. Use this as your foundation, focusing on the lengths to create a sleek surface that reflects light beautifully.
Follow with the L'Oréal Paris Elvive Glycolic Gloss Conditioner to seal in smoothness. Its glossing technology helps align the hair fibre and boost softness. Apply through mid-lengths and ends, leaving it on for a few minutes to amplify shine before rinsing.
Ouai Hair Gloss
Ouai's Hair Gloss works like a sealing topcoat. It boosts colour vibrancy and adds instant reflective shine. Use it once or twice a week after shampooing, leaving it on for five minutes to revive dull lengths and create that glass-hair finish.
Authentic Beauty Concept Glow Spray Serum
For lightweight luminosity, see the Authentic Beauty Concept Glow Spray Serum – it delivers a fine mist of gloss without heaviness. Spray it onto dry, styled hair, focusing on the outer layers to enhance light reflection and smooth flyaways for a polished finish.
Finish with Kérastase's Gloss Absolu Glaze Drops Hair Oil for a high-shine touch. This lightweight oil smooths and seals the cuticle. Warm a few drops between your palms (one or two is plenty for the fine-haired girlies among us) and press through the ends to lock in gloss and add a silky, mirror-like sheen.
So remember, behind every glossy strand is a product working twice as hard behind the scenes. As the old adage goes: Lay the groundwork, and the results take care of themselves!
