Can I use shop bought hair colourants on treated hair - eg L'Oreal Excellence

Hi, Gail,
There are 2 simple rules when considering having done Brazilian Keratin Treatment.
1. Have all colours - roots, highlights done before the treatment. I always ask my clients to wait 4-7 days before I apply BEOX or LaBraziliana treatment. In this time the hair will have time to absorb the colour, close the cuticles so I won’t strip it with the clarifying shampoo which is essential to use before the treatment.
2. If you have the treatment done already, wait 2 weeks to apply colour - roots. You can apply all over colour or highlights but you will strip some of the products off and it will not last you as long.
Hope this helps, call me if you need more info.
