I've colored my hair many times over the years. I've done my own roots. I've done my own highlights. But, this by far is way way good. I feel like I just stepped out of the salon. I have 22 inch long hair. The shampoo and conditioner after the coloring is absolutely amazing. I would've paid the full price just for the trial size packet of shampoo and conditioner. I use OLAPLEX on my hair to bond a couple of times a month. This time, I did not even have to use my Ola Plex products. My hair was perfectly matched to what I asked. I just don't see why anybody would not use them. I am a forever customer now.
