Declara powder is without dust and foam and without ammonia. Due to the presence of plex (lipo plex and keratin), hair is not damaged in any way. It also has polysugar, which gives hair lightening properties up to level 9 with a single charge. This powder is one of the best powders in the market due to its economical price and less consumption than other powders. Another advantage of this powder is that it is anti-hair loss. Also, due to the presence of polyquanteronium in this product, your hair will be soft and happy after use. One of the good points of this powder is that when the shelf life of the powder goes up for any reason (even inside the foil), the hair will not be damaged in any way. It is better to start with 9% oxidant.
