Kérastase Extensioniste

Kérastase Résistance Bain Extentioniste is the fortifying shampoo from the Extentioniste range for hair you want to grow long. It is designed for fragile hair prone to breakage. It cleanses deeply and strengthens the hair fiber from the roots.

What it does for you

• More elastic and stronger hair, from roots to ends.
• Restores the fiber's natural strength by strengthening and sealing its inner structure.
• Clean and balanced scalp, thanks to the purifying formula.
• Shine on the lengths and ends after every wash.
• Prepares the hair for the conditioner or mask from the same range.
• Rich lather and a delicate fragrance that leaves a subtle scent on the hair.

How to use it at home

1. Wet hair thoroughly.
2. Apply the shampoo and massage the scalp until it forms a rich, light lather.
3. Rinse thoroughly.
4. Follow with Résistance Fondant Extentioniste conditioner on the lengths.

For which hair type

For long or growing hair that is fragile, prone to breakage, and has weak ends. It is also suitable for color-treated hair that has become thinner on the lengths. If your hair is severely damaged by repeated bleaching, the Thérapiste or Première range provides more intensive repair.

Active ingredients

• Creatine R: an exclusive complex of creatine and ceramide. Creatine strengthens the hair fiber's inner structure, while ceramide restores its surface.
• Taurine: an amino acid that strengthens the fiber's inner structure and helps maintain a healthy scalp.

What else you need

• Résistance Masque Extentioniste Mask
• Résistance Fondant Extentioniste Conditioner
• Extentioniste Thermique Heat-Protecting Cream

ProBeauty Tip. If you want to grow your hair, schedule regular trims to remove split ends. Shampoo keeps the hair fiber strong, but ends that have already split cannot be reattached.

Kérastase Résistance Masque Extentioniste is the repairing mask from the Extentioniste line, for fragile, neglected hair. It penetrates the fiber and strengthens the strands all the way to the ends. Split ends are repaired and breakage is prevented, allowing hair to grow long and healthy.

What it does for you

• Uniform shine from mid-lengths to ends.
• Stronger fiber, with its natural resistance restored.
• Nourishes the lengths all the way to the ends.
• Sealed cuticles for smooth, soft-to-the-touch hair.
• Fewer breakages in long, fragile hair.

How to use it at home

1. Wash your hair with Bain Extentioniste and rinse thoroughly.
2. Towel-dry to remove excess water.
3. Take a walnut-sized amount and apply it to the lengths and ends.
4. Leave it on for 5 minutes, then rinse thoroughly with water.

For what hair type

For long, fragile hair with split ends or hair that breaks when brushed. It is also suitable for fine hair if you use a small amount. If your hair is short and only dry, a nourishing mask will be more beneficial.

Active ingredients

• Creatine R: an exclusive complex of creatine and ceramide. Creatine strengthens the inner structure of the strand, while ceramide restores its surface.
• Maleic acid: small particles that enter the fiber, strengthen it, and seal the cuticles evenly, from roots to ends.

What else you need

• Résistance Bain Extentioniste Shampoo
• Extentioniste Thermique Heat-Protecting Cream
• Résistance Fondant Extentioniste Conditioner

ProBeauty Tip. Detangle your hair with a wide-tooth comb while the mask is still in it. Start from the ends and work your way up to the roots, and you won't pull out strands when brushing after drying.

Kérastase Résistance Fondant Extentioniste is the reparative conditioner from the Extentioniste line, with a creamy and light texture. It detangles hair gently but effectively, so you can comb it without breaking the strands. Weak and fragile lengths receive active particles that strengthen the fiber along its entire length.

What it does for you

• Easy detangling along the entire length of the strand.
• Restores the natural resistance of the hair fiber.
• More elastic hair, from root to tip.
• Nourishes the lengths down to the ends.
• Sealed cuticles, for smooth, knot-free, silky hair after rinsing.

How to use it at home

1. Wash the hair with Bain Extentioniste.
2. Gently squeeze out the water and apply the conditioner to damp hair, on the lengths and ends.
3. Comb with a wide-tooth comb.
4. Rinse thoroughly.

For what type of hair

For long, weak, and fragile hair that tangles easily and breaks when combed. The light texture also works on fine hair. On very dry and coarse hair, alternate it with Masque Extentioniste.

Active ingredients

• Creatine R: exclusive complex of creatine and ceramide. Creatine strengthens the inner structure of the strand, while ceramide restores its surface.
• Maleic acid: small particles that enter the fiber, strengthen it, and seal the cuticles evenly, from root to ends.

What else you need

• Résistance Bain Extentioniste Shampoo
• Résistance Masque Extentioniste Mask
• Extentioniste Thermique Heat-Protecting Cream

ProBeauty Tip. Squeeze the hair with your hands before applying conditioner. On dripping wet hair, the product becomes diluted and no longer detangles as effectively.
