L'oréal's £6.50 volume spray is a miracle for fine hair - but how long does it last?

Luxury Beauty products often get a bad rap, with many assuming they're overpriced and offer little more than their more affordable counterparts.

But for my hair, the most impressive results have come with higher price tags.

That's why I was intrigued when L'Oréal Paris launched its new Big Hair Day Refreshing Volume Spray, a £13 (on sale for £6.50 at Boots) dry shampoo and volumiser hybrid designed for all hair types but especially those with flat locks.

With big claims of delivering a visible lift in just three seconds, I put it to the test on my oily scalp and two-day-old hair.

First off, the scent - while not the primary focus of a volume spray, fragrance is a big factor for me. At first spritz, the Big Hair Day spray gave off noticeable floral notes, which I wasn't a fan of as they were reminiscent of typical drugstore dry shampoos.

As per the bottle's instructions, I applied it in sections on dry hair, directly into the roots, then massaged the product into my scalp. The brand highlights the 'tri-dispenser applicator', which in practice meant I could distribute the product evenly across my head.

This was a massive tick in the 'yes' box because it helped avoid the white residue other sprays often leave on my coloured hair; actually, my roots felt super fresh and non-sticky, even after applying generously.

The results were instant and impressive - within three to five seconds, my roots looked visibly fuller, as if they'd been freshly styled. The formula uses a next-gen biomimetic collagen peptide technology to enhance texture by wrapping the hair fibre, so these results were to be expected.

One downside was that the lift didn't fare well throughout the day. After around three hours, my hair had lost that salon-worthy 'oomph', but after reapplying? It was soon back in business. So, it's worth noting that if you're someone who won't have time for a top-up every so often, you might be disappointed.

Seeing as I'd conducted this experiment on oily scalp hair, I was expecting not to be overwhelmed by the dry shampoo element in the product. But, while I wouldn't necessarily agree with my hair 'feeling' clean after so long, if we're talking about 'looking' clean? Absolutely. To my delight, this was a grease-free zone.

The verdict? Beyond being nothing short of a huge bargain, the Big Hair Day Volume Spray had me singing its praises. If you're looking for long-lasting results and have a little more cash to splash, go for the icons. But for £6.50? This is a seriously worthy purchase.
