The Best Ingredients & Vitamins for Hair

Haircare routines should function like skincare – and that goes for the ingredients used too. The best ingredients for hair protect and strengthen strands at their core. From hair care vitamins for scalp health to shampoo ingredients that improve shine, discover your personalised regime.

Why Should You Care About Hair Care Ingredients?

Your hair is unique. From your hair type to the stressors you encounter each day, taking care of hair requires a personalised approach. Kérastase formulations combine specific vitamins for hair, to treat a range of concerns and goals. For hair that is dry and damaged, in need of colour protection, or experiencing hair loss, find the best vitamins for hair alongside other ingredients.

What is skincare-inspired haircare?

Skincare-inspired haircare refers to the usage of ingredients that first rose to prominence in skincare products. Once just an afterthought, the importance of hair and scalp care is now becoming clear to more and more people, which has prompted the use of advanced formulations and powerful ingredients in haircare.

It turns out that just like your face, your hair and scalp require a thorough routine consisting of exfoliation, cleansing and conditioning. When we don’t take a tailored approach to our scalp and haircare, we can risk product build-up and clogged follicles, which can then lead to chronic scalp and hair conditions. By creating a tailored haircare routine, you’ll be able to treat the underlying causes of common hair issues like dandruff or hair loss and promote healthy hair growth.

When you consider the fact that the scalp has the same biological composition as the rest of our skin, it makes perfect sense to integrate skincare-inspired haircare into your routine. Here are some of our favourite products and ingredients.

A skincare ingredient with a cult following, hyaluronic acid also improves the hydration status of hair. The Kérastase range of hyaluronic acid shampoos, masks and creams improves the health of chemically treated or dehydrated hair.

Vitamin E for dull hair

Dulled hair colour and texture can indicate structural damage to strands. By applying antioxidant vitamin E to hair, you can promote hair growth and radiance.

Ceramides for smooth hair

Ceramides are lipids, a class of fatty acids. Naturally found in our skin cells, ceramides have naturally made their way into skincare and now, haircare products too. Ceramides occur naturally in our hair, but excessive use of heat, chemical treatments and cleansers can deplete these stores. This leads to raised cuticles, which show up in the form of dull, coarse and dry hair. Post colour or lightening treatment, ceramides are an important hair care ingredient for refreshing hair strength. By applying ceramides hair products, you can improve the binding of your cuticles and restore the appearance of your hair by helping to fortify and protect strength and colour.
