Scalp & Hair Care

Dual action balancing care for oily roots and dry ends

The quest for health begins with the quest for fresh. There is nothing like that freshly washed feeling. It’s a special thrill, stepping out of the salon or shower, walking into the world with impeccably clean, great-smelling hair. Fresh hair makes you feel light as air. But for those who struggle with an oily scalp, that feeling is fleeting. Hair never seems to stay fresh for long.

Kérastase introduces Spécifique Divalent, a complete care routine for oily roots and dry ends, with nourishing, healthy-hair care, and a next-level clean that lasts and lasts.

Spécifique Divalent Dual action balancing care for oily roots and dry ends

Bain Divalent



An ultra-light formula that balances scalp oiliness. The shampoo contains Amino Acid that gently cleanses the scalp and strands, attracting dirt like a magnet into micelles that can be easily rinsed away. These Amino Acid also works hard to balance healthy pH levels allowing for a super gentle cleanse. Amino Acid is also conditioning and reinforcing, it protects hair from environmental aggressors and assists weakened strands to hold onto much-needed moisture. Bain Divalent shampoo contains those all-important Amino Acid, alongside Vitamin B6, to effectively cleanse and balance oily roots and dry, sensitized ends without stripping them of moisture. A fresh scent that’s already loved by many for its aroma that invigorates the senses. With hints of Indian Basil, Freesia and Sandalwood, this fragrance leaves hair smelling beautifully clean.

Argile Équilibrante



A purifying clay that deeply, yet gently cleanses
and purifies the scalp. It also boasts this all-important Amino Acid ingredient alongside Kaolin Clay that draws sebum and impurities out of the scalp like a magnet. Used once a week instead of Bain Divalent, the clay purifies the scalp without stripping delicate strands. The Argile Equilibrante is scented with a fragrance we call Drop of Cloud. An airy composition, it is inspired by the fresh scent of skincare products. A heavenly scent it mingles hints of Earl Grey tea, with a generous roundness of Rose Essence and Cedarwood that softens the fragrance. It’s a treat for your scalp, strands and senses.

To Wash Every Day or Not

Upping the frequency of your hair wash days may seem like the logical answer to getting fresh hair, but daily hair washing can amplify and unbalance the all-important sebum cycle that can lead to unwanted scalp odor if you’re using non adapted products. Yes, it actually makes your scalp less fresh And this, in turn, drains moisture from your strands making hair drier than ever.

Getting Your Hair Balance Right

When you’re suffering from a sebum imbalance at your scalp and greasy roots that just don’t seem to budge, it can be tempting to over-wash your hair. But, if you’re looking to get rid of greasy roots, shampooing daily can strip your strands of moisture leaving them dry, brittle, sensitized and difficult to style, so you are left with more hair issues than you started with! Conversely, using rich products to nourish strands can clog the scalp leading to irritation or an overproduction of oil.

How to Get Rid of Greasy Hair

Kérastase 4 Tips to Get Rid of Greasy Hair

There is nothing more frustrating that washing and styling your hair for the roots to become greasy in what feels like mere hours. If this sounds familiar, then take comfort in the fact that you’re not alone. 20% of people have an oily scalp which means the roots get greasy pretty quick. Unfortunately, greasy roots have been wrongly linked to bad hygiene and they can knock confidence. So, what does cause greasy hair? And how can you keep those oily roots at bay? Below we reveal everything you need to know, including the products you can rely on to keep your hair looking fresh and grease-free.

What Causes Greasy Hair?

Kérastase 4 Tips to Get Rid of Greasy Hair

Everyone has a hydrolipidic film on their scalps, this fatty layer protects the skin and hair follicles from the environment (think UV rays and pollution), it also helps to keep hydration levels optimal. But some people have too much of this hydrolipidic layer. Why? Well, the causes are annoyingly varied. First up, there are external causes that can trigger an overproduction of this hydrolipidic layer. Those include heat tools, hard water, exercise and pollution. Second are the internal factors such as stress and exhaustion, an unhealthy diet, genetics and periods. Work through these factors and ask yourself which of these could be contributing to your greasy roots?

Kérastase 4 Tips to Get Rid of Greasy Hair

It’s important to get your scalp sebum under control because, especially for city-dwellers, if pollution gets trapped in the hydrolipidic layer it can cause the sebum on your scalp to oxidize which can lead to aggravation at the scalp such as itching or flaking.

Which Products Will Prevent Greasy Hair?

It’s often said that too frequent hair washing can lead to an overproduction of sebum but that’s not based on any solid scientific evidence. Whether you like to wash your hair daily or twice a week comes down to personal preference. The issue isn’t necessarily over-washing but not using the correct products that are suited to your scalp and hair concerns.

Use the Scrub Energisant in place of your shampoo once a week. Designed for oily prone scalp and hair, this scrub combats oiliness and even dandruff. The sea salt exfoliates to remove sebum, impurities and product build-up, while Vitamin B6 and salicylic acid protect the scalp and take down unwanted inflammation. You simply massage the scrub, using circular motions, into the scalp under a warm shower. The scrub lathers beautifully to unclog pores, whilst cleansing scalp and strands. Not only does this scrub tackle oily roots, 72% of people found they had more volume at the roots after application and their hair was shinier with a lightweight feel.


On your other hair wash days, use Spécifique Bain Divalent to bathe the scalp and strands. This scalp balancing shampoo treats oily roots by regulating the overproduction of sebum. It also nourishes the hair from root to tip leaving your strands soft and shiny. Over time, you’ll find that your roots will get greasy less quickly.

This silicone-free mask works in just 3 minutes to purify the scalp, treating oily roots, reducing dandruff and soothing an itchy scalp. Your scalp and hair will feel nourished and hydrated in no time.


For anyone using heat tools, it’s key to use a heat protector not just to protect strands but to prevent your scalp from overproducing sebum. L’Incroyable Blowdry offers thermo protection up to 450°F.
