Description

Gas supply device, use and method for lightening hair color Technical field

The invention relates to a gas supply device for lightening hair color, and the use of the device.

Background technique

Hair color is a problem that modern people are very concerned about. Nowadays, more and more young people will dye their hair to change the original hair color. Affect the appearance and self-confidence, will also look for ways to dye hair to improve the problem of gray hair.

The primary hair color of the hair is mainly related to the melanin produced in the hair follicles of the scalp. Melanin can be divided into eumelanin and pheomelanin, which is processed by tyrosinase through tyrosinase. As a result of a series of reactions, Asian scalp hair follicles mainly produce eumelanin, so their hair color appears black; while for Westerners with reddish brown hair, their scalp hair follicles mainly produce dark brown pigment, making their hair red. brown. As the age grows, hydrogen peroxide will gradually accumulate in the hair follicles. Hydrogen peroxide inhibits the activity of tyrosinase involved in the formation of melanin, causing the melanin production in the hair follicles to decrease, which in turn causes the newly formed hair to appear white, that is, The so-called gray hair.

Hair color can be effectively changed by dyeing hair. However, the dyes currently used in hair dyeing are all in liquid or gel state, which can easily touch the scalp and cause discomfort. The operation steps are lengthy, complicated, and even costly. . On the other hand, hair coloring agents often involve the use of chemicals that can remove, replace, and hide the pigments in natural hair. The use of these chemicals can cause a series of adverse effects, including skin irritation and allergies, hair breakage, and poor hair quality. According to research data from the International Agency for Research on Cancer (IARC), some dyes and chemicals used in the hair dyeing process are believed to increase the risk of cell mutation and carcinogenesis.

Therefore, there is an urgent need in the art to find a hair dyeing method that is easy to operate, low cost, and relatively free of adverse side effects, so as to improve the risk of harm to the human body caused by chemical dyes.

In addition, after the hair is dyed, people are often dissatisfied with the result of the dyeing. At this time, it is necessary to wait for the hair to grow back to return to the original hair color. Therefore, it takes a long time and waits for the new hair to grow out. It is necessary to maintain the unsatisfactory hair color; if you want to modify the hair coloring result in a short time, you need to perform bleaching, re-dyeing, etc. This method requires a large additional cost and is likely to cause further damage to the hair and skin.
