I naturally have mousy blonde hair. In the past I have been white blonde, ginger and dark red. I then started to use bright semi-permanent colours such as poppy red and fire red.
I recently decided that I wanted a pastel lilac/lavender colour, so I first used a colour stripper from Boots, then I bleached it, then I put on a violet semi-colour mixed with conditioner.
Now my roots are the colour I want it but my lengths are a light pink colour and my ends are white.
How can I get a consistent lilac colour from the roots to the tips?
The reason that you have different shades of colour is probably because the ends of your hair are more damaged and porous compared to the freshly bleached and toned roots.
When the hair is porous and sensitive, after repeated colouring and processing, toners like the violet one that you used have trouble staying put and rinse out leaving traces of the colour in different areas.
I would go with it and rock the different tones that are present in the hair. It's a lot more interesting that just having one shade!
