Did you know that oils don’t always stay fresh?
When oils are exposed to oxygen, heat and light, they can begin to oxidise. This process is often referred to as oils becoming rancid.
As oils oxidise, they can produce compounds known as lipid peroxides and free radicals. These compounds are associated with oxidative stress and may contribute to irritation and inflammatory processes within the skin.
What’s particularly interesting is that your scalp already produces its own natural oils, known as sebum.
Research has shown that oxidised scalp lipids can be associated with inflammation, irritation, microbial imbalance and scalp conditions such as dandruff.
This doesn’t mean oils are bad.
In fact, many oils can be beneficial when they are fresh, stable and used appropriately.
The real question is: what happens when oils sit on the scalp for prolonged periods, become oxidised and mix with dead skin cells, environmental pollutants and other buildup?
A healthy hair follicle relies on a healthy scalp environment.
That’s why scalp health isn’t just about what you put on the scalp. It’s also about what you remove.
Healthy cleansing helps remove excess sebum, oxidised oils and buildup, creating a cleaner environment for the follicle to function.
Because healthy follicles thrive in a healthy scalp environment.
