I was suspicious when the directions only had the dye on my head for 30 minutes total and no directions for grey coverage. As I feared it did not cover the grey and for some reason I’m having the hardest time washing the dye out of my hair. I washed twice and I can still feel it in my hair.

Hello AK! We are so sorry to hear about your frustrating experience with your grey coverage and rinsing our Olia Light Brown dye. For optimal grey coverage with our ammonia-free, oil-powered formula, it is important to apply the mixture to your most resistant greys first and let it develop for the full thirty minutes, ensuring the hair is completely saturated. Because Olia's nourishing formula is packed with sixty percent natural flower oils, a great tip to easily rinse it out is to add a small splash of warm water and massage your scalp thoroughly to emulsify the oils before performing a deep, thorough rinse until the water runs completely clear.

I got the vibrant red and it turned out very muted and coppery. Would not recommend. Barely even showed up

Disappointed with How Quickly Color Fades
We bleached my daughter’s hair the day before using Garnier Olia Bonding Care Bleach Kit, which we were satisfied with. The issue is the color dye. It looks great the first day or two, then starts to fade at an alarming rate. We used hair dye Garnier Olia Oil-Powered Permanent Color. When showering, she uses Garnier Color Shield Anti-Fade Shampoo and Conditioner and she’s managing the water temperature so only cold water touches her hair. I’ve never seen hair color fade this fast. My daughter and I are very disappointed and would not recommend. We are looking at other brands.

5 out of 10.
This was a 5 out of 10 for me. The price was great. The color was dull. The conditioning of my hair with this wasn't as advertised on the box. And did not like the color so much.

If you...
If you have a sensitivity to hair color, this might not work for you. Thank God for Benadryl! I broke out every place that hair color touched my skin. Oh go figure... the color was pretty.

Pleasantly surprised, I got box color results!
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.

Compliments Galore
[This review was collected as part of a promotion.] This worked really well and I am so happy with the coverage I received. I have dark brown hair and I wasn't sure it would even be noticeable. Everyone has complimented me on the color! And it doesn't have a harsh chemical smell either!

5.03 Medium Neutral Brown is the best brown color accuracy. The grey coverage is excellent and it kept my hair healthy looking.
