As painful as it is to say, I'm no stranger to bleaching my hair – post-breakup transformations never did me any good – and as a result, I've been left with some scraggly strands that are duller than my personality after a late Friday night.

So when the beauty world started talking about hair glosses, you can only imagine my reaction *checking bank account to see what the deal-io is*. Of course, the answer was quite spenny. But, if you're like me – a babe on a budget – I'm hear to spread the word about one of my fave glosses that has injected life and shine back into my hair. And did I mention it costs less than a tenner?

L'Oréal Paris' Elvive Glycolic Gloss Leave-In Serum is discounted RN in this October Amazon Prime Big Deal Days sale – a.k.a, Prime Day (less of a tongue twister, eh). Of course, this is the prime (sorry) time to stock up on things like tech, air fryers and even some fash buys, but I always use Prime Day to load up on the budget-friendly beauty products I love at least 'till 2026.

I've been shopping the Prime Day sale for year (you can check out all my fave picks here) but I simply had to give you the goss on this particular deal. Not only is the Glycolic Gloss the reason why I don't have hair shame anymore, but it has also been reduced from £15.99 to £7.99, making that a 50% off saving. Hello!

I know you're probably thinking 'I wouldn't spend £7.99 to sit with my friend on a RyanAir flight, so why spend it on a hair product.' Well, here's why this gloss is worth every single penny – and your friend can sit alone.

Fans of the product called it the 'WTF hair moment' on TikTok, with one user saying: "This guy just blew my hair straight and put a lot of it on and it's not giving oily. It's giving shiny, sheen, glossy. You're welcome!"

How does the magic work then? A few weeks ago I went to the L'Oréal Paris The Worth It Experience where I was treated to trying the product and discovered that it's all about the pearl pigments which give the hair a gorgeous, light-reflecting shine. The formula is also infused with glycolic acid to boost hydration and the overall silky finish – not to mention locking away those fluffy flyaways.

You don't need much either, so start with a small pump and glide it slowly down your hair. As a leave in product, you instantly notice the formula adding envious shine that only seems doable in a salon chair. But, if you wanna go the extra mile, you can add the Glycolic Gloss 5 Minute Lamination Treatment into your routine which is also included in the Amazon Prime Day sale.

IMO, there's no easier way to achieve glossy, salon-worthy results without the salon-worthy price tag. My bank account is happy and my hair looks like it has never felt the heat from a straightener. Each time I use it my strands feel enviously slinky and shiny and I can wave goodbye to my dull locks for GOOD. Winning!
