As a fellow brunette, it's no secret that I quite simply aspire to have Kate Middleton's hair (I'm sorry, but who doesn't?). Regularly experimenting with her hair, we've seen the Princess of Wales embrace warmer tones with some gorgeous honey highlights before, but we've also seen her opt for dark, mocha tones during those winter months. Despite changing her hair quite often, Kate always seems to have an envious head of hair, which looks ridiculously glossy and somewhat glass-like. You ask for her secret? Well, turns out it's the Kérastase Nutritive Gentle Hydrating Shampoo.

While it's widely said that the Kérastase shampoo is supposedly Kate's go-to for rinsing and repeating, we've spotted that the royal-approved hair product is, in fact, on sale right now, for just under £20 on Amazon.

If you're looking for a nourishing and strengthening shampoo, look no further than the Princess' favourite. This gentle, protein-enriched shampoo will deeply cleanse your hair and replenish its softness while also revitalising its shine. It's a no-brainer!
A customer said: "Since using this shampoo, my hair is extremely shiny and smooth and it’s much easier to blow dry and style. I would definitely recommend this shampoo if you have dry hair" and others included: "I really like the brand Kerastase, I’ve used it for years. The shampoo lasts ages too, I have thick hair but it only takes a small amount to do the job….go on buy it!"

Curious about what other haircare products our Princess swears by? Well, we've done a deep dive into Kate Middleton's mane, and through snippets that her trusted hairdresser Amanda Cook Tucker once shared of her royal tool kit on Instagram (however, it sadly got taken down), we've found the products the Princess reportedly has used on her hair before below.

Confirmed to appear in Tucker's royal tour tool kit, this affordable hair spray is what the established hairdresser has used to hold Kate Middleton's bouncy blowdries for many different occasions. It's a must-have for keeping those locks in place.

While Kate's thick hair does have a lot of natural body, Amanda Cook Tucker's kit reportedly featured this popular drugstore mousse. Keeping things lifted at the roots, this type of product always helps to hold any hairstyle - from bouncy blowdries to textured beachy waves.

For a more beachy, textured look, Amanda Cook Tucker always picks up this Ocean Spritz from affordable haircare brand Wella. For under £10, you can't go wrong.
