Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment 45ml

Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment is a targeted first step for hair that’s been weakened by colouring, heat styling or hard water. This lightweight gel formula is designed to be used before shampoo, helping to remove calcium build-up on the hair fibre while supporting a smoother, glossier finish. With pure acids including citric acid and caring ingredients such as glycine, it works to reinforce the feel of fragile lengths so hair looks stronger, more supple and less dull over time.

Ideal for all types of damaged hair, including dry, over-processed or brittle strands, this pre-shampoo fits easily into an existing routine. Applied to damp lengths before cleansing, it prepares the hair to receive the benefits of the Première shampoo, conditioner or mask that follow. Hair is left feeling softer and easier to manage, with a healthy-looking shine and a fresher, lightweight feel from root to tip.

How to use
How to Use:
Start with damp hair. Apply Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment generously to the lengths and ends before shampooing. Massage through to ensure even coverage. Leave on for around 5 minutes, then, without rinsing, apply your Première shampoo directly on top and lather. Rinse thoroughly and follow with Première conditioner or mask if desired.

Frequency:
Use as needed or according to the product instructions, particularly when hair feels dull, brittle or affected by hard water.

Application Technique:
Work the gel-like formula through mid-lengths and ends, gently massaging it into the hair fibre while avoiding the scalp if preferred. Comb fingers through to distribute evenly before layering shampoo over the top.

Best Practices:
Apply to clean, product-free hair between colouring or heat-styling sessions to help maintain a smoother, shinier look. Allow the product its full leave-on time before adding shampoo, and rinse thoroughly to avoid residue.

Safety Tips:
For external use only. Avoid contact with eyes. If irritation occurs, discontinue use and rinse with water. Keep out of reach of children and always follow the directions on the packaging.
