A luxury haircare brand reportedly favoured by Kate Middleton has reduced the price of one of its gift sets on Amazon. The Kérastase Genesis Travel-Size Discovery Gift Set contains a shampoo, conditioner, and a blow-dry spray.

Usually £33, it’s now on sale for £26.40 - a saving of £6.60 (20% off). The Genesis formulas are best suited for those who have weakened or damaged locks.

The shampoo gently cleanses and purifies your tresses. The conditioner strengthens and repairs, and the blowdry spray is a heat protector.

When visiting her London hairdresser, it's reported that Princess Kate often receives deep conditioning treatments using Kerastase products. No wonder her mane is so glossy.

The Kérastase Genesis haircare set has an average rating of 4.3 out of five, and more than 600 have been bought in the past month. It would make a lovely Christmas gift, or for yourself, as an introduction to the brand if you’ve always wanted to try the products.

Over in the reviews, one shopper commented: “I loved this shampoo/conditioner, definitely worth the money. It makes your hair feel amazing. Less breakage.”

A second added: “Perfect size for travel. The conditioner size is quite good and I imagine it will last me a while since a little goes a long way. Very happy with the product.”

A third added: “Beautifull smell. My hair is really fine. I have noticed less fallout.”

A fourth noted: “Nice gift set. Good quality. Good for fine hair.”

Not all shoppers were pleased with their purchase, with one saying the bottles were too small. They explained: “I use this Kerastase all the time. I know it’s expensive, but I couldn’t afford it this month, so I saw this cheeky travel one and figured that would last me until I can get the full size.

“Personally I think it’s a total rip off the bottles are so small and look a lot bigger in pictures. Nothing against the actual quality of the product as that is 100%. Just the quantity I think is a joke”

As Christmas is around the corner, there are lots of haircare gift sets currently available to snap up, including this Wella Professionals Ultimate Repair Rituals Gift Set. You can buy it now for £50; the contents are worth £74 in total.

Elsewhere, Boots has a Best OUAI's Kit on sale for £29. It contains a shampoo, leave-in conditioner, and anti-frizz spray.
