Long hair

Long hair symbolizes femininity, elegance, and vitality. However, the longer the hair grows, the more vulnerable it becomes. Dry ends, split ends, breakage, or lack of strength: these are all challenges to overcome to maintain healthy lengths. That’s why Kérastase created the Extentioniste range, specially designed to strengthen the fiber, stimulate growth, and preserve the beauty of the lengths. The first step of the ritual, the Bain Extentioniste gently cleanses while fortifying the hair fiber. Enriched with creatine R and maleic acid, this shampoo directly targets weakened areas for deep repair. The hair is more resilient from the roots, promoting healthy and continuous growth. The result: purified, lightweight hair ready to receive subsequent treatments. For long hair, the lengths and ends are often the most damaged. The Masque Extentioniste intensely nourishes, seals the cuticles, and prevents the fiber from weakening. Its concentrated formula reinforces the internal structure of the hair and restores its suppleness. The hair is shinier, softer, and split ends are visibly reduced. The essential step to complete the routine is the Sérum Extentioniste. Applied directly to the scalp, it stimulates growth and strengthens the fiber at the roots. Its lightweight formula acts as a vitality booster, promoting the growth of longer and stronger hair. When used regularly, it limits breakage and allows you to reach your desired length more quickly. By combining these three treatments – Bain, Masque, and Sérum Extentioniste – the hair regains its resilience and vitality. The scalp is stimulated, the roots are strengthened, the lengths are repaired, and the ends are protected. This complete routine ensures healthy, shiny, and supple long hair, without compromising on length or quality. Choosing the Extentioniste range means giving your hair an expert program designed for growth and strength. Thanks to the power of creatine R, your hair becomes stronger and grows back more robust. Ideal for those who wish to lengthen their hair without sacrificing its beauty, this professional range quickly becomes an essential ritual.
