Description
Kérastase Oléo-Relax Shampoo 250ml is a professional smoothing cleanser developed for voluminous, unruly and frizz-prone hair. Part of the Kérastase Discipline collection, this nourishing shampoo helps cleanse the hair while supporting improved smoothness, softness, manageability and natural-looking shine.
Hair that is naturally voluminous or prone to frizz can become difficult to control, particularly in humid conditions. Daily brushing, heated styling and environmental exposure may also contribute to dryness, flyaways and an uneven finish.
Kérastase Bain Oléo-Relax offers a professional cleansing step designed to make rebellious hair feel more supple and manageable before conditioning and styling.
Why Choose Kérastase Oléo-Relax Shampoo?
Unruly hair often needs a combination of effective cleansing and appropriate conditioning to maintain a smoother appearance.
When the hair surface feels rough, strands can become more difficult to detangle and may develop unwanted frizz.
Kérastase Oléo-Relax Shampoo belongs to the Discipline range, which focuses on improving the appearance and manageability of hair that is difficult to control.
The manufacturer describes this product as a control-in-motion shampoo that helps nourish hair while supporting easier styling.
Its smoothing properties make it particularly suitable for customers who want to maintain a polished finish without unnecessarily sacrificing natural hair movement.
The current UK product range also highlights shine-enhancing benefits for hair that appears dull or lacks radiance.
The shampoo provides a cleansing foundation before applying a smoothing conditioner, mask or finishing treatment.

Ingredients in Kérastase Oléo-Relax Shampoo
The exact ingredient declaration of the photographed Morpho-Huiles packaging is not visible.
The official current Kérastase UK product page provides an ingredient list for the manufacturer’s 250ml version.
Sodium Laureth Sulphate
Sodium Laureth Sulphate is a cleansing surfactant included in the current UK ingredient declaration.
It helps remove oil, everyday dirt and styling-product residue.
Important: This shampoo should not be described as sulphate-free.
Coco-Betaine
Coco-Betaine contributes to the shampoo’s cleansing and lathering properties.
It is used alongside other ingredients within the cleansing system.
Amodimethicone
Amodimethicone is a silicone-based conditioning ingredient.
It helps improve the appearance of smoothness and supports manageability.
Polyquaternium-10
Polyquaternium-10 is a conditioning polymer commonly used in shampoos.
It contributes to slip and the softer feel of hair during cleansing.
Shorea Robusta Seed Butter
The current UK ingredient list identifies Shorea Robusta Seed Butter.
This plant-derived butter is used in cosmetic products for its emollient and conditioning properties.
Marula Oil
Kérastase’s current UK product description markets the shampoo as Marula Oil-infused.
However, the published ingredient list on the same page does not clearly identify Marula Oil by its expected botanical INCI name.
Therefore, its precise presence or concentration in the photographed Morpho-Huiles version cannot be confirmed.
Fragrance Components
The current UK formulation lists fragrance ingredients, including Linalool, Citronellol and Geraniol.
Customers with known fragrance sensitivities should check the ingredient declaration on their purchased bottle.
For manufacturer product information, see the official Kérastase UK Discipline Bain Oléo-Relax Shampoo 250ml page.
The exact 250ml product is also listed at Boots UK.
Ingredient note: The manufacturer and some UK retailers publish different formulation information. The physical bottle’s ingredient list should take priority when confirming ingredients, allergens and claims for the actual stock.

Extra Tips for Best Results
Use lukewarm rather than excessively hot water when washing frizz-prone hair.
Massage gently and avoid unnecessary friction through the lengths.
Follow shampooing with a suitable smoothing conditioner or mask.
When drying, gently squeeze out excess moisture using a microfibre towel.
Apply an appropriate heat protectant before blow-drying or using straighteners.
For a sleeker blow-dry, direct airflow along the hair lengths while using a suitable brush.
Avoid repeatedly passing heated styling tools over the same section.
In humid conditions, a compatible anti-frizz finishing product may help maintain a smoother appearance.
