From the Nivea Styling Mousse Extra Strong Level 4, is to say that it in no way strengthens extra strong. But with it is a good styling possible and that's what matters to me. As with (almost) all mousses comes when operating the pressure relief valve to my mind out way too much. Once pressed briefly and you've got a tennis ball sized amount into the palm of his hand. It is positive that the foam of this mousse is not equal to coincide so I can distribute portions small amounts in hair with the other hand. If I knead my shoulder-length, fine hair with it, I get beautiful curls (if me feels like it). I want more volume, then I comb my hair after drying the mousse again by then and have grippy, voluminous hair that I like. The scent of Nivea Styling Mousse Extra Strong is very discreet. If I only use the mousse, so no hairspray / spray, then I do not feel that my hair from any burden or something is complained, in other words, the mousse will be completely absorbed by the hair. So I do not see the necessity of it in the evening to brush intensely. For completeness, I would like to mention that this product contains several less recommendable ingredients (Propane, Cetrimonium Chloride, butanes) and two non-recommended ingredients (Isobutane, Benzophenone-4) according codecheck.info. They are used in propellant and as a preservative.
