Ahead are other contributing factors, and what you can do to stop hair colour fading.
Exposure to bright sunlight can erode the vibrancy of natural and treated hair colour by destroying both melanin pigments and dye molecules.
Contact with UV radiation is unavoidable, but just with skin, there are proactive measures you can take to protect the vitality of hair. UV degrades the colour molecules that are formed during the dyeing process, causing colour to fade and reducing shine.
The risk of damage to hair strands and colour is heightened in Australia, where the levels of UV radiation are some of the highest in the world. To stop hair colour fading, limit direct exposure when outdoors. Wearing a hat and minimising sunlight by staying in the shade reduces UV contact and allows the keratin in hair to remain, which supports the strength and look of hair.
The chlorine used in swimming pools can cause strand friction, damaging the hair cuticles and encouraging hair breakage. Hair colour (both natural and dyed) is also affected through this chemical disinfectant.
The bonding behaviour of chlorine attaches itself both to the natural melanin of hair and dyeing chemicals, stripping colour and increasing dullness. To combat this, soak hair with water before swimming to reduce the amount of chlorinated water absorbed by strands. Follow by rinsing hair directly after swimming to limit the effects of the chemical.
Salt and seawater
The process of dyeing hair strips strands of water. The layer of salt in sea water adds to this, by further pulling moisture from already damaged locks. This increases the friction placed on strands, leaving hair vulnerable to breakage and reducing the reflective shine of hair.
To combat this, always rinse hair right after swimming in seawater, and consider wearing a cap if regularly swimming.
Styling without heat protection
The pressure applied to hair strands through styling tools causes stress both to the dye molecules and the outer layer of hair. If you style your hair regularly, support the long-term appearance and feel of locks through the use of a heat protectant.
Products like heat protectant sprays coat the cuticle of the hair with silicone before styling, to prevent heat damage and lock moisture into the strand.
