The only diy highlights
I only use this product for highlights. I'm always happy with the results. It brightens my grey and darker hair and evens it out. The trick is getting the timing right. For me, 45 minutes is the minimum. I recommend doing a strand test to see how long the hair takes to reach your desired shade. I also shampoo with a purple shampoo afterwards - for me this only needs to be done once and effectively tones the highlights.
