Without a doubt facial wrinkles and hair loss are sure signs were getting older but for some grey hair is more obviously than anything else. Trying to reverse grey hair or at least hiding it has been in the works since the times of ancient Egypt man who had struggled to disguise the problem.
Methods Of Trying To Reverse Grey Hair
One of the earliest methods used was “Henna” which is a flowering plant used since antiquity to dye hair, skin, fingernails and even leather and wool which gives a reddish appearance.
Coal tar was another popular substances that was relied upon to color grey hair also.
Facts is hair color is the pigmentation of hair follicles due to two types of melanin, these are eumelanin and pheomelanin. Typically the way it works is the more melanin present, the darker your hair will be and on the flip side the less melanin there is will causes hair to become lighter. Melanin, a type of protein can be denatured by various chemicals, including bleach. This is how dark hair is transformed into blonde hair.
Melanin And How To Reverse Grey Hair
As we’ve noted, two types of pigment give hair its color: eumelanin and pheomelanin. Pheomelanin colors hair red. Eumelanin, which has two subtypes of black or brown, determines the darkness of the hair color. A low concentration of brown eumelanin results in blond hair, whereas a higher concentration of brown eumelanin will color the hair brown.
High amounts of black eumelanin result in black hair, while low concentrations yield gray hair. All humans have some pheomelanin in their hair.
Pheomelanin is more chemically stable than black eumelanin, but less chemically stable than brown eumelanin, so it breaks down more slowly when oxidized. This is why bleach causes darker hair to go through a reddish phase during the artificial coloring process. As the pheomelanin continues to break down, hair gradually becomes orange, then yellow, and finally white.
Levels of melanin can vary over time causing a person’s hair color to change, and it is possible to have hair follicles of more than one color. Gray or white hair still today called “salt and pepper” when it is ‘peppered’ throughout dark hair, is not caused by a true gray or white pigment, but is due to a lack of pigmentation or melanin.
At the present time there is no medical (i.e. permanent) means to restore melanin pigment lost due to aging to reverse grey hair. As with efforts to reverse pattern hair loss, the basis for restoring hair pigment comes down to molecular medicine. Using a gene modulation approach, the goal would be to ‘turn on’ melanocyte producing genes so that the pigment producing cells could once again populate the hair with it’s natural color.
The development of a stem cell-based technique would yield actual melanocytes capable of being replaced in the hair follicle so that they could resume their production of eumelanin and pheomelanin. In either theoretical technique the potential to modulate melanocyte expression is likely. In plain English, this means that a person could choose whatever shade of hair he or she wishes perhaps even sades of purple or green not found in nature.
