Black Friday week has officially begun, bringing a plethora of fantastic beauty deals worth adding to baskets immediately. Luxury haircare brand Philip Kingsley is one such label starting the savings early, offering 30% off its bestsellers, viral favourites and expert-approved treatments.
The British retailer is well-known for its scientific approach to hair and scalp health, and this year’s Black Friday event covers everything from targeted treatments for dry, damaged and brittle hair to soothing solutions for flaky, itchy scalps. Fans will find travel kits, bumper gift sets and online exclusives included in the offer, perfect for both stocking up and gifting.
Philip Kingsley products are renowned for their results, but they sit at the higher end of the price range, making this an excellent time to shop. This rare discount provides the perfect opportunity for anyone dealing with dryness, damage, thinning or scalp irritation to try the formulas that so many experts swear by.
Philip Kingsley Black Friday sale 2025
As someone who’s tried a fair few Philip Kingsley products over my years as a shopping writer, I’ve compiled the top picks genuinely worth shopping during the sale, reports OK!. Scroll down for my favourites.
Density Discovery Collection – £49.35, was £70.50

For those dealing with thinning hair or excessive shedding, the Density Discovery Collection, now 30% off, is definitely worth a look. The trio comprises the Density Thickening Shampoo and Conditioner, alongside a full-sized bottle of the Density Preserving Scalp Drops.
Each product contains intelligent ingredients, including hyper-branched polymers for volume without causing dryness, and ceramides, which help restore lost lipids in damaged hair. Combined, the collection aims to reduce hair loss, promote scalp health and enhance overall thickness.
One satisfied customer commented: “It has really helped change my hair immensely. I had very sparse hair on the sides of my forehead, my parting, and my scalp; all of that has gone in three months. My hair looks and feels transformed.”
Elasticizer Deep-Conditioning Treatment (150ml) – £27.30, was £39

The Elasticizer is arguably Philip Kingsley’s most celebrated product, and with good reason. Renowned for reducing breakage after a single application, this pre-shampoo treatment restores elasticity, enhances bounce, and delivers deep hydration to parched strands.
I’ve kept it in my routine for years, and it reliably leaves my hair feeling healthier, shinier and considerably smoother. Dry ends disappear almost immediately.
My only quibble is that it’s not an instant solution. It needs to be applied to damp hair and left for around 20 minutes, meaning you do have to plan ahead. A more straightforward alternative is Olaplex’s Rich Hydrating Mask (£29.25 from £38, LookFantastic), which can be applied after shampooing.
Body Building Discovery Collection – £30.80, was £44

I’ve battled with limp hair for years, but Philip Kingsley’s Body Building Collection has genuinely made a difference. The discovery set includes four volume-enhancing products designed to lift fine hair, add fullness and deliver a glossier finish.
The root boosting spray and plumping cream are real highlights for me – both used after washing to maximise volume and make hair feel instantly thicker. My only advice is to use the plumping cream sparingly. A little goes a long way, and using too much can leave hair feeling slightly sticky, so less is definitely more.
Alternatively, I also like Drybar’s Southern Belle Volume-boosting Root Lifter (£18, Boots). This lightweight mousse is easy to apply before drying, and always leaves my tresses feeling uplifted.
Bond Builder Split End Remedy – £21, was £30

This smart formula works hard to protect and strengthen strands, helping to seal split ends and prevent further damage. Impressively, the results last up to three washes, meaning shoppers get longer-lasting benefits between uses.
Enriched with hydrolysed oat protein, it softens the hair’s texture whilst aiding moisture retention and hydration, making it perfect for those grappling with frazzled or stressed tresses. Indeed, one individual remarked: “It has saved me countless trips to the hairdressers, and you get a ton of compliments about how healthy your hair looks.”
On the other hand, another person observed: “I haven’t noticed any difference in using this product, but the fragrance is nice.”
