Longer hair? Go to the extreme! There is no denying it, waiting for hair to grow can be a long and painful process. Fortunately, it doesn't have to be that way! Redken has just launched Extreme Lenght, the new range that will help your hair reach the length you dreamed of, strengthening it to reduce breakage by 81%. The best way to help your hair achieve a new length is to combine key internal and external factors to achieve this goal. Internally this means a balanced diet, rich in vitamins and nutrients that your body needs to be healthy - healthy hair has the potential to grow between 15 to 30 cm per year.
