Have you ever thought your hair extensions could be damaged by sunscreen spray? Why is that?
What sunscreen spray ingredients can cause hair extensions to discolor?
Avobenzone is a synthetic dibenzoylmethane derivative, also known as Butyl Methoxydibenzoylmethane. It is a synthetic sunscreen ingredient that efficiently absorbs a wide range of UVA wavelengths, providing broad-spectrum protection against UVA radiation. It is classified as a "chemical" sunscreen agent because it works by absorbing longer UVA rays and converting them into less harmful infrared radiation (heat). Avobenzone is oil-soluble and widely used in sunscreens. It is considered a broad-spectrum sunscreen agent as it can protect against UVA rays across the entire spectrum. It is one of the few UV filters that offers broad protection and is therefore extensively used in sun protection products. In cosmetics, it also helps prevent the degradation of other ingredients under sunlight exposure.

Test results have shown that Avobenzone's effectiveness as a sunscreen decreases significantly with prolonged exposure to sunlight due to its degradation. To overcome this limitation, most sunscreens containing Avobenzone are formulated with photostabilizers such as octocrylene. Octocrylene is known for its stability and provides effective protection when exposed to sunlight. It stabilizes Avobenzone, allowing it to perform its intended function. The combination of Avobenzone and octocrylene is necessary for optimal sun protection, covering both UVA and UVB rays. When hair extensions come into contact with sunscreen sprays containing these ingredients, the hair color may change to orange, pink.
Not all vendors use the best quality raw materials, this is because most of the raw materials available in the market for hair extensions are treated with a lot of acidic chemicals and soaked in silicone in order to make them look smooth, soft and frizz free.These acid chemicals and silicone interact with sunscreen, sweat, or other chemicals, leading to a change in hair color.
