Description

Hair Dye with Coloring Effects and A method of using the same

The present invention relates to hair dyes, hair dye kits and hair dyeing methods.

Conventional hair dyes are mainly oxidative hair dyes mainly composed of synthetic hair dyes (p-Phenylenediamine (aka PPD) and PPD derivatives).

PPD has the advantage of short hair dyeing time, while the hair dyeing process causes severe hair damage, especially serious allergies to the human body, There is a problem in the safety of the human body as a hair dye such as there is a report that causes bladder cancer, kidney cancer in a professional worker who has been exposed to these hair dyes for a long time.

Due to these safety problems, natural hair dyes have been steadily developed, but there are disadvantages in that the color development is insufficient and the time required for color development is long, and some natural hair dyes are easily discolored due to sunlight, or discolored due to temperature or pH change. There was a problem.

Moreover, it was not easy to perm and dye simultaneously using the existing dye. The reason is that the perm is generally composed of a first agent mainly composed of a reducing agent and a second agent mainly composed of an oxidizing agent (or neutralizing agent), and the dyeing agent comprises a coloring agent (or hair dye), a mordant (or colorant), and a coloring agent. It consists of an oxidizing agent that promotes the binding of mordant, and the reducing agent, the main component of the perm agent, inhibits oxidation of p-phenylenediamine (PPD), which is mainly used in dyeing agents, so that it is not dyed and the oxidizing agent is used in dyeing agents. If included, the reducing agent, the main component of the perm is oxidized to inhibit the action of the perm. In addition, the oxidizing hair dye using the oxidizing agent after the perm using the oxidizing agent, if you want to dye immediately, the damage of the hair is large, so the inconvenience of having to dye separately at regular intervals of one week or more to recover the damaged hair after the perm. There was a ham. For this reason, perm and dyeing could not normally be done at the same time, and there was a problem that the inconvenience and cost to be separately increased.

On the other hand, gentian has only been known to inhibit hair loss by inhibiting the action of 5a-reductase in human hair follicles in relation to hair (Korean Patent Publication No. 2002-0050261). Is unknown.

The present inventors have studied to develop a natural hair dye which can not only have excellent coloring effect but also dyeing at the same time as a perm, it has been found that the gentian extract is the main substance showing the hair dye effect, and completed the present invention.
