In the year 2016 in the month of February, a team of researchers in Japan detected that dwindling collagen levels near hair follicle stem cells is associated to hair loss. The absence of this specific type of collagen, type XVII collagen, leads to the destruction of hair follicle DNA. Scientists have observed this occurrence in mice that were almost 18 months old, which is the age at which mice start to shred their hair. Older mice have thinner as well as fewer hair follicles in comparison to younger mice. The study revealed that hair loss was not so common in ageing mice which continued to produce collagen.
In mice that typically lacked type XVII collagen, the damaged stem cells ultimately turned into skin cells and were sloughed off just like dandruff. This lead to hair follicle shrinkage as well as hair loss. Scientists believe that the same mechanism also works on humans.
In an independent study of the human scalp, the Japanese researchers found that the hair follicles of women in their 50s or older were smaller in comparison to the hair follicles of women in their 30s as well as 40s. Scientists are delighted about these findings as it could help them find the cure for baldness other than hair replacement.
Collagen is recognized for helping to restore a youthful complexion, but its benefits are more than skin deep. Collagen is essential to healthy skin, hair, and nails and is also a naturally occurring protein in the body. Collagen is key to one’s hair quality and structurally reinforces it. It is the building block of the hair and surrounds each strand.
The fundamental component of hair is keratin protein, that is produced most effectively by the body when there is an adequate supply of amino acids in our bloodstream. This supply of amino acids can be raised by drinking a high-potency collagen supplement, as it is in no time absorbed by our small intestine. The amino acids present in the supplement are used by the hair follicle cells in order to produce this critical keratin protein.
Collagen also helps in increasing blood circulation in our body. Increased blood flow to our scalp is directly beneficial in boosting hair as well as scalp health. Another benefit is that our hair follicles would receive the required nutrients, which in turn assists our hair in growing faster.
Sadly, for many of us, as we age, our hair becomes coarse and dry. Consuming a high-potency collagen supplement can be helpful to treat dry, brittle hair as collagen increases the moisture level in hair and also aids in repairing the annoying split ends. An added bonus: collagen supplements often also help to reduce the prevalence of gray hair.
