Hair Colour Banding
You know when you Colour your Regrowth and slap the Colour through your ends, hoping it will bring some vibrancy back into your Hair and then after you have washed and blow dried, you see a bright, vibrant Colour at your roots and darker, less vibrant version of your Colour through your ends? That is what we call Colour Banding. When your Hair has different stages of Colour through it, showing up in bands of Colour.
Why does Colour Banding happen?
When you apply new Hair Colour to your fresh Regrowth and over the old Colour through your ends, it adds another layer of Colour over the Hair. This creates horizontal bands of Colour through your Hair from your previous Colours.
How do I get rid of Colour Banding?
To fix Dark Colour Bands, Colour Remove your ends to help remove the Colour Build Up, giving more attention to the lengths of your Hair. If you plan to re Colour, take particular care on the Colour Removed parts of your Hair as they will absorb the new Colour more than your Natural regrowth. Follow So I've Colour Removed Now What for more information.
For Lighter Colour bands try using Highlights to break up the Colour Banding.
How can I prevent Colour Banding from happening?
When doing touchups, apply the Colour to your Regrowth only, trying not to overlap onto your old Colour.
If you want to add some vibrancy through your ends use the Colour Top Up Technique during the last 10 minutes of processing time to avoid banding.
