It says it can be applied like hair dye on natural or colored hair or highlighted hair. But, it says to wait 3-4 weeks after coloring hair to use it. After 4 weeks, I color again!
If anyone has used this product or is familiar with it, please let me know. Also, what would be the reason for waiting 3-4 weeks to use it?
I've never hears of this until yesterday, so any info appreciated. Thanks.
