Grey hair has become a huge phenomenon
So many people are letting their natural beauty shine...
But one of the little things that happens is that it can turn yellow...
Sometimes really yellow...
One big reason this happens is oxidation.
Yes, that incredibly useful thing that we use to lighten natural melanin and develop dye precursors...
It can also be damaging and incredibly unpredictable at times.
In grey hair it is definitely unpredictable...
Or predictably chaotic
☀️ UV light is made of tiny particles of energy called photons. When those photons hit the hair, they excite melanin fragments, amino acids, lipids, and trace minerals left behind from hard water and
They aren't matter, but they interact physically with matter. Transferring energy that sets chemical reactions in motion🤯
That excited energy helps convert ordinary oxygen into reactive oxygen species (ROS)...highly reactive forms of oxygen that interact with chemical components in the hair to create brand new yellow chromophores.
These yellow compounds aren’t melanin. They’re oxidation byproducts…
A little the compounds that cause the pages of an old book to yellow over time.
That’s why UV exposure is, in my opinion, the biggest reason gray hair turns yellow.
and it is one we don't address enough.
Chelate for sure!!
But, UV protection and antioxidant leave ins are a must!!!
