The intensive hair mask, enriched with argan oil and keratin, is specially designed for dull and damaged hair, particularly that which has been dyed or treated with protein and keratin. Thanks to its nourishing properties, this mask repairs and hydrates the hair, making it softer, shinier, and easier to style. Usage Instructions: Apply a generous amount of the mask to clean, damp hair. Gently distribute the mask from the roots to the ends. Let it sit for 10-15 minutes. For deep hydration, consider using a steam treatment. Rinse the hair thoroughly.
