Menard has developed a formula based on Korean red ginseng and black winter truffle extract. In a previous study, the company tested these extracts in a formula to promote hair growth.
The formula has been successfully tested on an artificial scalp model developed by Menard, which allows him to assess hair growth at a “Test tube level”.
Red ginseng is steamed and dried in a special process developed by Menard, who dubbed the product “super ripe red ginseng”.
This hair formulation has been tested on 20 men and women. The 20 subjects were instructed to apply the hair tonic to half of their scalp for three months to examine the preventative effect of these extracts.
After three months, the team analyzed the hair samples and confirmed that the formula stimulated expression of the CXCL12 protein.
Increasing the production of CXCL12 in the hair was imperative to prevent the graying process of the hair.
Moreover, a comparison of the two halves of the scalp showed that the half treated with the lotion has less white hair, proving that the extracts were effective in preventing the growth of white hair.
The company said it will apply the new discovery to the development of new hair care developments targeting pigment stem cells.
Menard Cosmetics was established in 1959 and develops a range of cosmetic products and operates a chain of beauty salons. He has also established businesses in the hospitality industry.
Black and white assessment
The cosmetics company developed this formula after undertaking to analyze the difference between black hair and white hair in detail using stem cell analysis technology.
Previous studies have shown that pigment stem cells can be found in the bulb of the hair follicle.
According to the firm, the amount of pigment stem cells tends to decrease due to factors such as aging or stress.
According to the company, this suppresses the production of melanocytes and eventually turns gray.
Through the research process, the team discovered that a protein called CXCL12 plays an important role in the graying process of hair by maintaining pigment stem cells.
By comparing black hair and gray hair, the researchers found that CXCL12 expression was reduced in white hair.
The company believes that when the expression of CXCL12 weakens, the supply of melanin is blocked and leads to the formation of gray hair.
“As a result of comparing black hair and white hair, it was found that CXCL12 expression was reduced in white hair. In other words, it was believed that the cause of gray hair was a decrease in the expression of CXCL12 in the bulb, which made it impossible to maintain pigment stem cells and disrupted the supply of melanocytes.
Menard has been studying stem cell technologies since 2003.
