An intensive conditioning treatment that focuses on reconstructing and repairing the hair whilst imparting shine and softness, kérastase masque force architecte has been designed for damaged, weak and dry hair that needs its strength restored. Brittle and weak strands lack ample amounts of keratin proteins so this deeply conditioning mask has been formulated with pro keratin which imitates the behaviour of keratin to help rebuild the hair. As damaged hair is strengthened, split ends are less likely to occur and locks begin to feel more supple and elastic. Working from the inside out, ceramides boost natural shine and ensure moisture is retained so hair looks healthier and more luminous. To hydrate even further, the mask is enriched with resurrection plant sap – a plant that thrives in even the most dehydrated of circumstances – to thoroughly condition even the most damaged and weak hair. Expect shinier, softer hair that’s restored and strengthened as well as protected from breakage and split ends. Apply to freshly washed and towel dried hair by massaging in from lengths to ends and leaving on for 5 minutes before rinsing out.
