Spitzen sehen wieder gepflegt aus. Hitzeschutz ist für mich ein Plus. Nicht gerade günstig aber für mich hat es sich gelohnt.

Kérastase Résistance Fondant Extentioniste

Kérastase Résistance Fondant Extentioniste is a length-strengthening conditioner from the new hair care protocol for longer hair. The conditioner supports the restoration of the outermost hair fiber layer. The Creatine Complex enhances hair flexibility and strengthens the hair structure. Additionally, the formula is enriched with Maleic Acid, which can penetrate the hair fibers thanks to micro-particles and seals the hair evenly from the roots to the tips. Thanks to these valuable ingredients, hair breakage and split ends are prevented. Application Tip for Kérastase Résistance Fondant Extentioniste After cleansing the hair with the Extentioniste Shampoo, the conditioner is applied to towel-dried hair. Ideally, leave it on for 1-2 minutes and then rinse thoroughly.

Kérastase Résistance Bain Thérapiste

Kérastase Résistance Bain Thérapiste is the first balm-like shampoo for very severely damaged and over-processed hair. The gel-like texture envelops the hair fiber, reducing friction during washing. The hair fiber is protected and safeguarded against further damage. Valuable ingredients such as Fibra-Kap and Sève de résurrection revitalise severely damaged hair, restoring shine and smoothness. Fibra-Kap is a complex of Pro-Keratin, 6 amino acids, Gluco-Peptides, and wheat protein hydrolysate. It is similar to the hair's own proteins and is responsible for building the hair structure and maintaining the cohesion of the hair fiber. Sève de résurrection is juice from Myrothamnus Flabellifolia, a plant that can bloom again after 10 years of drought, and it provides shine and revitalisation to damaged hair. Application recommendation for Kérastase Résistance Bain Thérapiste Fine hair: first work the Soin Premier Thérapiste into damp hair, leave it to work, then rinse out. Next, distribute the Kérastase Résistance Bain Thérapiste shampoo thoroughly through wet hair and leave it to work for up to 3 minutes. Rinse well and repeat with shampoo if necessary. Thick hair: apply the Kérastase Résistance Bain Thérapiste to damp hair. Massage a hazelnut-sized amount well into the scalp and work approximately the same amount into the lengths. Leave to work for up to 3 minutes and then rinse thoroughly. Repeat if necessary. For optimal care results, follow with the Masque Thérapiste.
