However, some of the biggest bargains are to be found in the beauty aisle, across tools like hairdryers and straighteners, to skincare products from Medicube, Wonderskin and Laneige. One deal I would recommend snapping up is Olaplex’s No.3 Plus Complete Repair Treatment, now reduced from £32 to £22.80. Olaplex No.3 Plus Complete Repair Treatment This three minute pre-shampoo treatment reduces frizz, improves softness, boosts shine and is now 29% off in the sale. Buy Now for £22.80 (was £32) – save 29% Earlier this year, and a decade on from its original No.3 formula, Olaplex reworked its famous pre-shampoo treatment to creat a new formula that works quicker and more efficiently to treat heat and chemical damage, after just one use. When it first launched, I put it to the test to see if there was any difference, and it was such a noticeable improvement that I had to share, especially now it’s on sale with almost 30% off. It’s basically a pre-shampoo treatment that needs to be applied to wet hair, left for three minutes then rinsed out as followed up with your usual shampoo. It’s the product our hair has been dreaming of. (Picture: Metro/Amazon) The new formula is made with a technology called ‘damage defence cationic complex’, which repairs the hair cuticle, locking in moisture, boosting shine and reducing frizz. It’s also got an added benefit of a conditioning element thanks to the avocado and sunflower oil, as wells as thickening ingredient, hydroxypropyl starch phosphate. Fans of the original No.3 treatment may remember it had to be left on for 10 minutes, so the new version cuts down the time and makes it more convenient, especially if you’re rushing out the door in the mornings. It’s recommended for use every one to three washes, so this sale price is a welcome opportunity to try it for yourself, or top-up your routine while it’s reduced.

My hair is full of bleach, and while I love my highlights, I don’t love the damage it’s done to my hair. That, combined with using heat on a regular basis with my hairdryer and curling wand, means my hair could use a bit of TLC. Wow! Would you look at those gorgeous results! (Picture: Metro/Amazon) A 50p-sized amount is enough to coat my entire head, but I have naturally straight fine hair, so if you have curls or thicker strands, you’ll probably need more. After towel-drying my hair, it’s a lot less knotty than normal with much less frizzy even when I rough dry it. It’s a lot more convenient than the original formula, so if you’re trying to treat dry, brittle hair that’s looking a bit limp, it’s a one-stop-shop to better hair days. With it now on offer in the Amazon Prime Big Deals Day sale, there’s no better time than now to treat yourself to a bottle.
