Since my first application of Elumen hair color I use Elumen Lock. It is used to seal the hair after coloring and ensures long-lasting color results. After washing hair color around 40ml Lock should be applied and remain on the head for 5 minutes. As a very uncomfortable I feel for more than 2 years time and again the smell of the product, which has a chemically and unhealthy. Also on the hands, it is rather unpleasant, you should wear gloves. Good washing is very important, as I have already had the experience that a "quietschiger" film remains on the hair, if you do not tidy enough washes, which makes much more difficult later and the hair itself unruly and dry a comb through the hair.
Since Elumen itself is quite expensive, I would not renounce the use of lock - it guarantees approximately five weeks lasting hair color (which is, however, dependent on their own perception Some would probably want to re-dyeing long.).
