I have a love-hate relationship with my hair. Love? When I’ve just had it done. That glossy colour and fresh cut never fails to give me a boost, making me feel that touch more put together. You know what? Maybe my hair isn’t so bad after all! But then the London water has other ideas. Honestly, anyone who colours their hair will know the struggles of hard water- it strips away moisture and fades colour within days. And then comes the brassiness. My fresh blonde turns into a coppery-toned orange, and just like that, the despair sets in.
Do I chop it all off? Do I book more regular refresher salon appointments, despite my protesting bank balance? Surely, somewhere in the ever-evolving realm of hair trends, TikTok would have a solution for me. ‘Glass hair’ is everywhere right now. I've lost count of how many creators I've come across, each whipping their gleaming locks across my feed with reckless abandon. But it’s a trend that seems better suited to the non-bleached among us, those with hair in its untouched, virginal state. For us with highlights or colour, however, ‘glass hair’ can feel like a distant dream.
That’s when I discovered hair glazing. The aim isn’t the seemingly unattainable ‘glass hair’ finish, but rather an improvement on what you already have. It’s about smoothing the cuticle for added shine, bounce, and health- plus a little colour refresh, too, if you so wish.
'Hair glazing is a semi-permanent treatment that focuses on adding shine and smoothing the cuticle of the hair,' says celebrity hairstylist and Grazia beauty panellist Tom Smith. 'These products can be found with or without tone or pigment, meaning they can add translucent colour to your hair- toning away yellow or orange hues-or simply enhance shine, making your colour and texture look salon-fresh again.'
You could absolutely try a glaze via a toner at your next salon visit, but thankfully there’s a product currently doing the rounds on social media: Glaze Supergloss Sheer Glow, £15.99

What is Glaze Supergloss Sheer Glow?
Glaze describes the product as a 'tinted moisturiser for your hair'- which I absolutely love. Think of it as a subtle boost to enhance your natural hair, rather than completely overhaul it. It’s not designed to overload strands with texture-altering silicones or sulphates (which can add shine but also weigh down hair). Instead, it gently enhances your hair’s existing texture and colour. It's your hair, but better. While Glaze’s glosses also come in tinted versions, the one I'm testing is clear to deliver shine, softness, and radiance. The effects last up to 5 washes, giving you all the benefits of a salon gloss without the hefty price tag.

Rachael Martin Beauty Director: The result? Genuinely stunning. My blonde looked brighter and fresher, and my hair was noticeably shinier and softer. The cuticles are flatter, making my hair look sleeker and bouncier. Dry brittle ends? Gone! Just like that! Typically when I curl my hair I contend with a lot of excess frizz, but this wasn't the case here. My hair is literally glazed with a protective layer of gloss and it lasted all day. While it's not quite glass hair, I'm definitely on my way. Hooked

How to Use Glaze Supergloss Sheer Glow
It couldn’t be simpler. After shampooing, rinse your hair and squeeze out the excess water. Hair should be damp, not dripping wet. Then apply the gloss in sections, from root to tip. I like to gently comb it through to ensure even distribution. At this point, I usually twist my hair up into a claw clip and leave it for 10 minutes- plenty of time to indulge in an everything shower. Then rinse and style as usual. It's that simple.
Our Verdict
Rachael Martin, Beauty Director says:
'The first time I tried this gloss, I knew I had to share my thoughts- it’s that good. I have greasy hair, so I’m normally cautious with conditioning products, but I needn’t have worried. The texture is light- not buttery- sitting somewhere between a gel and a milk, so I knew it wouldn’t weigh my hair down. I applied quite a lot of product, probably close to a handful, and ran it through my lengths and ends. I then added a smaller amount to the roots before brushing through.

Amazingly, even when wet my hair felt slippery and silky-soft. After rinsing (I took a few extra minutes to ensure it was properly rinsed out) I blow-dried my hair and styled it with a curler. The result? Genuinely stunning. My blonde looked brighter and fresher, and my hair was noticeably shinier and softer. The cuticles are flatter, making my hair look sleeker and bouncier. Dry brittle ends? Gone! Just like that! Typically when I curl my hair I contend with a lot of excess frizz, but this wasn't the case here. My hair is literally glazed with a protective layer of gloss and it lasted all day. While it's not quite glass hair, I'm definitely on my way - just look at the amped up shine in my before and after photos. Hooked!'

Tom Smith, Grazia's beauty panellist says:
'Almost everyone can benefit from a gloss now and then. For those who colour their hair, it’s an ideal way to revive dull ends and extend colour life safely. For those with natural hair, a clear gloss can add a reflective, mirror-like shine. It’s particularly helpful if your hair feels lacklustre, frizzy, flat, or compromised after the summer. For best results, shampoo your hair twice with a deep-cleansing or clarifying shampoo to remove any build-up or residue that might be dulling your shine. Then follow with the gloss for maximum impact.'
