As he explains María Castán, scientific expert of Wella ProfessionalsTo color our hair permanently we need to use, in addition to coloring pigments, an alkaline substance such as ammonia, MEA, etc. along with the peroxide. These two ingredients are necessary to open the cuticle and color the hair.

Ammonia is a chemical that has been used in permanent colorations for more than 50 years. The reason is that it has proven to be the best technology in terms of performance – results of coloring – and hair protection.

Its bad reputation and "aggressiveness" are a consequence of its strong smell which, in turn, is what makes ammonia one of the best, if not the best, ingredient for the coloration discovered so far.

Why? Ammonia is a very small molecule that fulfills its function of aiding in coloration and then evaporates. That is the reason we can smell it. Thanks to this evaporation, and consequent smell, ammonia does not remain in the hair preventing it from causing reactions with hair proteins. It just disappears.

<p>Let's set an example so that it is better understood. If we make a small cut on the finger, we use alcohol to disinfect. At first it stings, that means he is doing his disinfectant work, and immediately evaporates (for this reason it can be smelled). If it did not evaporate, the finger would sting permanently until we cleared it. This is precisely what happens with other ingredients that do not smell and do not evaporate, remain in the hair or worse in the scalp until they are cleared, and while they continue to react with the hair.</p>

The look …

The seduction of the simplicity it translates into this look that he proposes Indola. It is a version of Bob A-line where the hard work lies in the surface of the cut. The look is characterized by the movement given by the longer tufts on the crown and the honey and hazelnut tones They give it depth. The color chosen for this look is a chocolate-copper, a warm tone that gives the look that modern tone that a current girl needs to wear a classic style. The wicks create an effect of reflections and lights, since the blonde naturally stands out above the base. The colors are very important in this cut since they give it a very beautiful depth.
