Cat Deeley has always had truly lovely hair, so it may surprise you to learn that the secret to her shiny, nourished strands can cost you less than £18...

If you're anything like us, the current climate is making good hair days few and far between. Humidity can wreak havoc on all hair types, but especially colour-treated and bleached ends that often require some extra TLC, from products like the best shampoo and conditioner, to look their best.

To keep her thick, highlighted hair frizz-free, Cat swears by the Kérastase Nutritive shampoo for its hydrating and smoothing powers. It may be more expensive than many of the best drugstore shampoos, but if Cat's hair is anything to go by, it's more than worth the investment. And with 30% off right now, there's no better time to stock up and ensure your hair looks its best no matter the weather.

Why Cat Deeley loves Kérastase Nutritive Bain Satin Shampoo

Shampoo is one of those products that many people overlook in their beauty routine, assuming that the cheaper options work just as well as premium buys when it comes to the "is expensive shampoo better?" question. While this can be the case for some hair types, a good quality shampoo can make all the difference for dry, frizzy hair that may require more effort to style. Cat herself has noted that her hair is something she invests in, saying, "I need products that are super-duper because my hair is really thick and big and crazy! I’m a Kérastase girl and I love its Nutritive Bain Satin Riche Shampoo."

Kérastase makes everything from the best shampoos for fine hair to the best heat protection sprays, and the price point does marry up with the quality. Although styling tools can work small miracles when called upon, your hair will look its best when it is properly nourished and prepped, starting with the right shampoo for your hair type.

We don't expect this generous discount to stick around long, so if you're looking for an antidote to frizz and dehydration, your hair will thank you for investing in one of the best.

What is the difference between Kérastase Nutritive Bain Satin and Bain Satin Riche?

When it comes to the best Kérastase shampoos, the brand has two different types of Nutritive products: Bain Satin and Bain Satin Riche. While the regular Bain Satin products can be used on normal to dry hair, Bain Satin Riche is designed for very dry hair that needs as much moisture as it can get. You may want to switch between the two as the weather changes or use Riche year-round if your hair is damaged or you find needs to take on a lot of moisture.
