Thin, fragile hair is just as happy to be repaired and strengthened right down to the roots as other hair types. That said, care treatments that are too creamy weigh down fine hair so that it quite literally goes limp. Strengthening Repair Mask causes no such problems. Its clever formulation masters the balancing act between intensive care and a volumising effect. A complex of plant proteins and algae extracts repairs the hair deep down and smooths and seals the surface of the hair without weighing it down.
