  • Great on UNBLEACHED HAIR 😊👍
Color: Tanzanite
Wife says: Perfect with 20 vol developer on UNBLEACHED natural hair! No need to bleach first of you want a subtle dark blue. My natural color ranges from grey, dark blonde, to brunette. You can see the different shades of blue on all my different natural shades, that's why there are different shades of blue. I recommend. Much better price inside the Sally's shop, but was nice to be able to order online to try it first before going to the shop TO BUY SEVERAL MORE 😆 ... show more

  • ION 4N cream hair dye
Color: 4N Medium Brown
I love this product. The color is beautiful. My hair feels soft and manageable, not dry and tangled. My hair has always been dark, I'm nervous to let the grays/whites grow out. That being said, I get wonderful gray coverage. I love that it is a cream and not a liquid. Liquids are very drippy and make a mess for me. I like cream better as it stays where I put it with no dripping. I usually dye my hair every six weeks so the subscription is a perfect choice. You can change the color, quantity and subscription delivery time any time you need to. Hope this helps someone. 😊 ... show more

  • Repeat customer to this brand but first time purchasing online
Color: 1V Jet Black
I usually buy my Ion Hair Dye from Sally’s but to save me a trip I decided to buy online. I particularly never used “jet black” before but I always pick in the black family so it was good enough. I specifically purchase this brand because it’s PPD free (I am allergic to PPD). Upon opening the package I was a little nervous since the tube had a different appearance from the one from Sally’s. I also read the back of the bottle and it had references to “black henna” which I found odd (or maybe never noticed on the Sally’s one idk) I hopped online to see the reviews and to my disbelief I saw some comments stating it’s really not ppd free. I was nervous. I looked up how to do a patch test - but unfortunately it takes about 24 hours and I had to dye my hair asap so I decided to do it anyways. I left it on for a 30 minutes and everything felt fine. After I washed it out I was so nervous that I might get a reaction but I am happy to report 8 hours later everything turned out fine. :) ... show more

  • Does not work
Color: Sapphire
I don't write reviews for hair dye because it does what it's supposed to do.... dye your hair, except Ion. I bought the sapphire color, bought 2. My hair is already a greenish/blue, but it is currently faded so a dark color like the sapphire should take Upon opening the product, it smells horrid. It smells like bleach, the whole bathroom smelled. It actually smelled worse that when I actually bleach my hair. Oddly the dye is a cream color so I'm not sure how it works or how it was supposed to dye my hair that blue tone. I left it on for over 40 minutes with no change AT ALL. I've never had a hair dye do that or lack of doing something. I can not emphasize enough how much I DO NOT recommend this product. Update: it actually discolored my hair now that it is washed out and some of my hair is still a faded blue and other parts are yellow. I'm so livid. ... show more

  • before and after ^^^
Color: 1V Jet Black
idk maybe i just have what they call as black hair dysmorphia, cuz to me it just looks dark brown… like don’t get my wrong it did actually dye my hair but it didn’t dye it like black enough. i feel like this dye would be good for someone going for a natural black color, but i wanted like pure black. also it like has a fragrance to it and to me the fragrance is like really annoying and gross plus it sticks in my hair forever. maybe it’s just cuz im sensitive to smells but its annoying that the smell just stays in my hair even after washing a few times. oh yeah and i feel like it fades a bit, i only washed it twice after dying it so far and it already faded enough. probably best to get a good blue black dye for a super black color ... show more
