By enriching the hair fibre, the forumla highlights the graceful contours of curly hair, from the waviest to the frizziest of curly hair types. Kérastase Discipline Curl Idéal uses a unique dual-formula technology to create a Pro-Keratin and Elastin complex, which works to discipline and define curls, creating a desirable springy effect while ensuring the hair fibre remains nourished.
