Title: Method for promoting hair growth and improving white hair condition, and device and apparatus thereof

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a method for promoting hair growth and improving white hair condition, and a device and an apparatus thereof. 
     2. Description of the Prior Art 
     Melanin can be divided into eumelanin and pheomelanin, which is produced by tyrosine through a series of reactions with the help of tyrosinase. Hair color is related to the melanin produced in scalp hair follicles. Asian scalp hair follicles produce eumelanin, so the hair color is black. In westerners with reddish brown hair color, hair follicles produce pheomelanin, so the hair color is reddish brown. When hair follicles are used to make melanophore of the melanin instead of making melanin, the newly produced hair will appear white, which is the so-called white hair. 
     In recent years, some scholars have discovered through human hair follicle cell culture and by observing human white hair that a large amount of hydrogen peroxide will be produced when the hair follicle is damaged; and when the amount of enzyme (catalase) responsible for decomposing the hydrogen peroxide in the hair follicle is insufficient to remove the hydrogen peroxide, the hair will turn white, and a large amount of hydrogen peroxide will be accumulated in the hair shaft in the white hair. What&#39;s more, the hydrogen peroxide can inhibit the activity of tyrosinase participating in the formation of melanin, thereby reducing the yield of the melanin in the hair follicles. 
     In addition, some studies have pointed out that scalp hypoxia will enables the hair follicles to enter a programmed cell death state, resulting in damaged and atrophic hair follicles, abnormal hair loss, less hair and finally baldness. 
     Modern people love beauty, and less hair and white hair are generally regarded as a symbol of aging, so when the hair is reduced or turns white, the appearance and self-confidence will be seriously affected. Therefore, when it is found that the hair is reduced or turns white, many people will actively seek ways to improve. 
     One of the most common way to improve white hair condition is to dye hair to mask the white hair that has grown. However, hair dyeing can only mask and improve the white hair that has already grown, and the chemical substances included in hair dye may injury human body. In recent years, some studies have pointed out that some hair dye ingredients can increase the risk of cancer. 
     The common way of effectively improving hair loss and reduced hair amount is hair transplantation surgery. The hair transplantation surgery is to implant hair follicles into the scalp area where the hair amount is to be increased and grow new hair after the implanted hair follicles survive. However, the hair transplantation surgery is usually expensive, and there are problems of whether the implanted hair follicles can survive successfully and maintenance. 
     Therefore, how to promote hair growth simply and without irritation and make the grown hair have the original hair color has become an important subject to be solved by the present invention.
