Do not pre lighten your hair!
Otherwise each time you want to retouch your root area you will have to have the same process, this will cost you extra money. ...More >
If you have your hair pre lightened first you will find your red fades much faster as your hair will be more porous due to the lightening process.
What I would recommend is having the lightest vibrant red shade you can as a permanent colour as a full head application, with woven highlights introduced. After the highlights have been introduced you could have a vibrant red stainer applied, like Sebastian Colourshines as this will increase the tone of not only your highlights, but the overall full head red colour on the rest of your hair.
The colour shine product is also fantastic for refreshing your tone and will not affect the condition, in fact it will help the condition.
