If your hair looks greasy only a day after washing, you’re not alone. Oily hair is one of the most common hair concerns, and finding the right shampoo can make a noticeable difference. Many people wonder: Which Kérastase shampoo is suitable for oily hair?
The answer depends on whether your scalp is oily, your hair lengths are dry, or you’re dealing with excess sebum alongside dandruff or sensitivity. Fortunately, Kérastase offers several professional shampoos designed to target these specific concerns while keeping your hair healthy, balanced, and lightweight.
In this guide, we’ll explain the causes of oily hair, recommend the best Kérastase shampoos for oily hair, and help you choose the right formula for your hair type.
Why Does Hair Become Oily?
Your scalp naturally produces sebum, an oil that protects both the scalp and hair. However, when the sebaceous glands produce too much oil, hair quickly becomes greasy, flat, and difficult to style.
Several factors can contribute to an oily scalp:
- Overactive sebaceous glands
- Hormonal changes
- Fine hair that becomes greasy more quickly
- Product buildup
- Washing with overly harsh shampoos
- Frequent touching or brushing
- Environmental pollution
Using the wrong shampoo may strip the scalp of natural oils, causing it to produce even more oil in response. That’s why choosing a balancing shampoo is essential.
Best Kérastase Shampoo for Oily Hair
1. Kérastase Specifique Bain Divalent
For most people with oily roots, Kérastase Specifique Bain Divalent is the best choice.
This balancing shampoo was specifically developed for people who experience:
- Oily scalp
- Dry or sensitized lengths
- Flat roots
- Hair that feels greasy shortly after washing
Unlike clarifying shampoos that can leave hair feeling stripped, Bain Divalent gently cleanses excess sebum while maintaining moisture throughout the mid-lengths and ends.
Benefits
- Removes excess oil from the scalp
- Purifies without over-drying
- Leaves roots feeling fresh longer
- Adds softness to dry ends
- Creates lightweight volume
- Suitable for frequent use
This shampoo is especially popular among people with combination hair—where the scalp becomes oily but the ends remain dry or damaged from coloring or heat styling.
2. Kérastase Symbiose Bain Pureté
If your oily scalp is accompanied by dandruff, Kérastase Symbiose Bain Pureté Anti-Pelliculaire is an excellent option.
Unlike traditional anti-dandruff shampoos that may leave hair feeling heavy, this formula helps remove flakes while reducing excess oil and maintaining scalp comfort.
It’s ideal for:
- Oily scalp
- Visible dandruff
- Itching
- Scalp discomfort
- Product buildup
The formula cleanses deeply without compromising the hair fiber.
3. Kérastase Specifique Bain Vital Dermo-Calm
Sometimes an oily scalp is also sensitive or irritated.
If your scalp becomes greasy while also feeling itchy or uncomfortable, Specifique Bain Vital Dermo-Calm may be a better solution than an intensive purifying shampoo.
It helps:
- Calm scalp irritation
- Remove impurities
- Gently cleanse oil
- Reduce discomfort
- Leave hair soft and manageable
This shampoo works well for people whose scalp reacts easily to harsh cleansers.
Which Kérastase Shampoo Is Best for Oily Hair and Dry Ends?
Many people actually have combination hair rather than simply oily hair.
Signs include:
- Greasy roots within one day
- Dry ends
- Frizzy mid-lengths
- Hair colored or bleached
- Split ends
In this situation, Kérastase Specifique Bain Divalent remains the top recommendation because it balances both concerns at the same time.
It purifies the scalp while preventing the lengths from becoming rough or dehydrated.
How Often Should You Wash Oily Hair?
One common misconception is that oily hair should be washed several times a day.
In reality, excessive washing may encourage the scalp to produce even more oil.
Most professionals recommend washing oily hair:
- Every other day
- Every 2–3 days if possible
- After intense exercise when necessary
Using a professional balancing shampoo instead of a harsh cleansing formula can help extend the time between washes.
Tips for Managing Oily Hair
Choosing the right shampoo is only part of the solution.
To keep your scalp balanced:
Avoid very hot water
Hot water stimulates oil production and may irritate the scalp.
Focus shampoo on the scalp
Massage shampoo into the roots rather than scrubbing the lengths.
Condition only the ends
Applying conditioner directly to the scalp may make hair appear greasy sooner.
Avoid heavy styling products
Rich creams and oils can accumulate around the roots.
Clean your hairbrush regularly
Hairbrushes collect oil, styling products, and dirt that transfer back onto freshly washed hair.
Reduce unnecessary touching
Running your fingers through your hair transfers oil from your hands to the scalp and hair.
Ingredients That Help Control Oily Hair
Many Kérastase shampoos include ingredients selected to balance the scalp while protecting the hair fiber.
Depending on the formula, you may find ingredients that help:
- Remove excess sebum
- Gently cleanse impurities
- Maintain scalp comfort
- Support healthy-looking hair
- Improve softness and shine
- Preserve moisture in dry lengths
Rather than aggressively stripping oils, these formulas focus on restoring balance, which often produces better long-term results.
How to Build the Ideal Kérastase Routine for Oily Hair
For the best results, pair your shampoo with complementary hair care products.
A simple routine could look like this:
Step 1: Wash with Kérastase Specifique Bain Divalent.
Step 2: Apply conditioner only from the mid-lengths to the ends.
Step 3: Use a lightweight leave-in treatment if your ends feel dry.
Step 4: Avoid applying oils or styling creams directly to the roots.
Following a consistent routine helps keep the scalp fresh while maintaining healthy-looking lengths.
