I was so nervous to try and color my light brown hair that was color treated. It had been 6 months since my last color, but I used a professional custom home service and it was never quite right. My hair pulls red easily and I have to tone a lot. I have a lot of chemical sensitivities so the semi permanent colors had more of an effect on my skin than the permanent because they washed out and I was exposed every wash. I just can't do ammonia or bleach anymore because of asthma and dry scalp. I can't afford the salons and have been cutting my hair and doing my own color since the pandemic in 2020. I watched a lot of color theory videos and many try on simulations for every company. I was prepared to suffer through an ammonia process until I saw this and saw that it had no silicones and parabens, which I have to strictly avoid in all products now. I can't find it anywhere on the box, but I am sure I read somewhere that Olia doesn't pull brass and that's why I chose it. The try on tool was also very useful in choosing the color. I did go with the lighter color as suggested. My light brown/dark blonde was very dull from medical issues. I wasn't expecting more than a shine and really expecting a reddish dark blonde as that's usual for my hair. I can't believe I got the box color results. I chose the lightest ash blonde hoping it would be enough coolness to give me a golden natural blonde with no brass. I got the darkest results color on the box and I'm so happy. I did use one purple tone rinse before I dried it the first time, but I didn't need it. It was a temporary one and actually dulled the final result a little. The second wash I held off the purple and used a good shampoo to clarify and it's so much shinier and brighter. I followed the directions exactly with very dirty hair and timing, though my hair is so short I really do an all over application quickly and then let it set for the full time. I am so happy with this result. Now I wonder if I use the same color or go to the 9 so it doesn't go blonder. I guess my roots will still need this color. My hair feels nice and my scalp is not drier than before. Since I can avoid toners it's a win and I can work on my scalp in between colors. My hair is short because of thin patches after menopause and medication. I don't have gray yet, so this gentle color gives me time to grow my hair back. I really recommend trying it if you need a gentle color and want to avoid brass. I'm allergic to nearly everything in beauty. I did do a patch test and strand test, though my strand test was darker than my beautiful final result, probably because my mixture was off.

Hands down the best hair dye I’ve ever used. The color match is perfect and it blends seamlessly with the white streak at the top left of my hairline. I also love how gentle it is—no harshness, and my hair and scalp feel healthy and soft after each use.
