The present invention relates to a method of levelling hair colour, especially the hair lighter coloured or including lightened streaks or bleached streaks or bleached as a whole and after certain period of time contrast - difference in colour - between the re-growth and formerly lightened parts is clearly visible. The first objective of the present invention is a method for levelling colour of hair comprising at least two parts wherein one part being the part not closer to scalp which is artificially colour changed to a lighter colour by means of lightening and/or colouring and/or bleaching than the other part closer to scalp which is preferably undamaged and has its natural colour, wherein hair is optionally shampooed and optionally towel dried and the part directly at the scalp, preferably undamaged and preferably having its natural colour, is applied a composition resulting from mixing two compositions. A and B, prior to application, wherein composition A is an aqueous composition and comprises at least one oxidizing agent and has an acidic pH, preferably between 2 and 5 and composition B is a substantially anhydrous composition and comprises at least one compound with bleaching effect, and composition thus obtained has a pH between 8 and 12, and processed for up to 10 min, preferably between 2 and 8 min, more preferably between 2 and 7 min and most preferably between 2 and 5 min (all values are included) at a temperature between 20 and 45°C, preferably at an ambient temperature and rinsed off from hair and hair is optionally dried.
本发明涉及一种平整发色的方法,特别是发色变浅或包括变浅的条纹或漂白的条纹或整体漂白的头发,经过一段时间后,重新生长的部分和以前变浅的部分之间的对比--色差--清晰可见。本发明的第一个目标是一种用于平整头发颜色的方法,该方法至少包括两个部分,其中一部分是不靠近头皮的部分,通过减淡和/或染色和/或漂白的方法,人为地将其颜色改变为浅色,而另一部分是靠近头皮的部分,最好是未受损的,具有天然颜色,其中头发可选择洗发,也可选择用毛巾擦干,直接靠近头皮的部分,最好是未受损的,最好具有天然颜色,涂抹由两种组合物混合而成的组合物。其中组合物 A 是
水性组合物,包含至少一种氧化剂,pH 值呈酸性,最好在 2-5 之间;组合物 B 是基本无
水的组合物,包含至少一种具有漂白效果的化合物,由此得到的组合物的 pH 值在 8-12 之间、在 20 至 45°C 的温度下,最好是在环境温度下,处理不超过 10 分钟,优选 2 至 8 分钟,更优选 2 至 7 分钟,最优选 2 至 5 分钟(所有数值均包括在内),然后从头发上冲洗下来,并可选择将头发干燥。
