Kérastase Resistance Bain Extentioniste: Strengthening Shampoo 250ml

Kérastase Resistance Bain Extentioniste is a strengthening shampoo created for hair that’s struggling to reach its ideal length. The lightweight, foaming formula works to cleanse the scalp and lengths while supporting the feel of stronger, more resilient hair from root to tip. Enriched with Creatine R™ technology, a blend of creatine, ceramides and taurine, it helps to reinforce the hair fibre, improve the feel of elasticity and promote the look of healthy, freshly washed lengths.

Ideal for weak, brittle or slow-growing hair, this shampoo fits easily into an everyday haircare routine. It gently lifts away impurities, excess oil and product build-up without leaving hair feeling stripped, so lengths feel smoother and look more polished. Used regularly, it helps to support a scalp environment that feels comfortable and balanced, so hair can appear longer and stronger over time. Massage into wet hair, enjoy the fresh, salon-inspired fragrance, then rinse thoroughly before following with your chosen Kérastase Resistance conditioner or mask.

How to use
How to Use:
Wet hair thoroughly. Apply a small amount of Kérastase Resistance Bain Extentioniste to the scalp and lengths. Massage to create a rich lather, then rinse well. Repeat if desired, and follow with a suitable Kérastase Resistance conditioner or mask.

Frequency:
Use as needed, or according to the product instructions on the packaging.

Application Technique:
Apply directly to wet hair, focusing first on the scalp before working the lather through mid-lengths and ends. Rinse with warm water until the water runs clear, ensuring no residue remains.

Best Practices:
Use on thoroughly wet hair to help the shampoo distribute evenly. For longer hair, detangle gently with fingers while the lather is in the lengths. Pair with complementary Kérastase Resistance treatments to support the feel of stronger, smoother hair.

Safety Tips:
Avoid contact with eyes. If contact occurs, rinse immediately and thoroughly with water. For external use only. Discontinue use if irritation occurs and follow any additional guidance on the product packaging.
