At Bella Nani, we know that grey hair happens, and not always on purpose! It is part of nature and we fully support those who proudly wear their “wisdom highlights”. We also know that many opt to cover them with hair color and styles. Recently, some scientists discovered the actual cause of grey hair and baldness! We found the article and are happy to share it with you!
Grey hair is something many people have no interest in.
Sure, it may be trendy to have granny-coloured hair on Instagram, and we’re all for rocking what’s natural if you want to, but if we’re being honest, the first spotting of those pesky greys can be a little disconcerting.
And don’t even get us started on balding … because that’s something most of us want to avoid at all costs, too.
So you’ll be thrilled to hear that while University of Texas Southwestern Medical Centre researchers were studying a rare genetic disease, they accidentally stumbled upon the cells that cause our hair to grey.
And it has something to do with a protein called KROX20 that could potentially get rid of both greys and baldness.
Here’s where the science comes in.
In a new study published this week in the journal Genes & Development, researchers working on mice discovered that KROX20, which is usually associated with nerve development, acts as a switch to turn scalp cells in hair shafts — which then allows cells to create something called stem cell factor (SCF). And SCF matters because it’s responsible for the pigment in your hair.
So when researchers removed the SCF protein from cells in mice, their hair turned white. And when the KROX20 protein was deleted, the mice went bald.
Allure notes that hair pigmentation does not have a backup system, so when SCFs are altered and their level falls below a certain threshold, there is no support for the protein. The result? White hair.
