I love this product. I mix the blue and purple together (Midnight Indigo and Purple Tanzanite) to get a color-shift effect—sometimes it looks purple, sometimes blue, and in certain lighting it shows both. This is the only dye I’ve found that I’m not allergic to, it actually lasts, and it doesn’t damage my hair. The color holds for about three months even though I wash my hair every day with Native’s volumizing shampoo and conditioner. I don’t use any other styling products—just the shampoo, conditioner, and this dye. I’ve been using it since I was around 11 or 12, and I’m 26 now. My hair has always stayed healthy with it. It also works really well on my tape-in 100% human hair extensions. I got them on a whim to see what I’d look like with four extra inches, and the color took beautifully. My only complaint is that the shades I use are almost always out of stock in stores, so I usually have to order them online. But I’m so loyal to this product at this point, I wouldn’t switch anyway. First photo is most recent last photo is with the tape in extensions in, they are currently out I’m going to touchup my roots and put them in after❤️❤️❤️
