Blondies, brunettes and redheads, today we are talking about you! Girlfriend, if your hair is on the dark side of brunettes, has a reddish roll like Emma Stone, or is more of a very legal blonde, it's not a matter of luck, it's science (and genetics, obviously)! And today we'll tell you why.
What effect does melanin have on hair?
Did you know that the molecule responsible for your hair color is none other than melanin? It is a pigment produced by the melanocytes at the root of the hair follicle, and is distributed throughout the hair fiber, except for the cuticle, which is composed of colorless cells that allow us to see the natural color of our hair.
Now, my friend, two types of melanin are involved in this cool pigmentation process : eumelanin and pheomelanin, and they are the culprits that make you belong to one clan or another. The production of these pigments is a complex process, as both types of melanin are polymers made of various proteins.
If you belong to the brunette team, your hair will be dominated by eumelanin, which provides the darkest colors, including brown and black, while if you belong to the redhead or blondie team, your hair will contain much more pheomelanin, which provides the reddish, orange and yellow colors.
In addition, the structure of melanin changes from one hair to another, and in lighter hair,diffuse melaninappears, whose granules are smaller in size and are present in smaller quantities. On the contrary, in darker hair, these granules are much more present and are larger, what is not?
Can a person have different hair colors naturally?
Hair color varies throughout an individual's life: many people are blond as children and become brunettes in adolescence.
This is because as we become adults, this is the time when certain genes are activated and the protein composition changes.
Why do gray hairs appear?
But wait... what about gray hair? Okay, here comes the drama moment. When a melanocyte stops functioning, melanin is no longer produced, and the hair fiber is no longer pigmented, and voila, gray hair in sight!
As I guess you can imagine, stress and bad vibes play an active role in making this happen prematurely, so keep calm, girlfriend!
Oh, and they are not really white, but transparent, but the play of light around us makes them have that whitish color that we see.
💜 Tip: to take care of your gray hair, we recommend using Le Blonde Shampoo.
Last but not least, as we have told you before, my friend, the natural color of your hair, and whether you belong to the blonde, redhead or brunette clan, is pure and simple genetics, because all the information about the number of melanocytes, their distribution, their potential to produce melanin in your hair, and the predominant type of melanin, is written in your genes!
