Best dye for covering Grey/white hair
I'm on a journey to get my hair healthy again as it had started to go thin due to menopause. I used to bleach my roots every 8 weeks or so in order to have bright fashion colours ( pink/ purple ) , and with doing this a lot of hair at the nape of my neck and around my hairline had broken off. Since having ditched the bleach and the broken parts now growing back in nicely my hair was starting to look a bit drab as I have lots of white hairs at the root ( about 4 inches worth ). I was just using my usual semi permanent colours, but after about 3 washes the white hair was popping through again and sticking out like a sore thumb. I spent a good deal of time looking for purple colours on Amazon that cover grey/white hair. And I came across this one which is permanent. It's not going to do as much damage to my hair as bleach will as it is a conditioning based permanent dye so I'm so happy that I can now carry on having purple 💜 hair without struggling on how I'm going to cover my white hair and risking more damage to my hair. This hair dye is absolutely amazing, it is thick in consistency as it is a conditioning based permanent hair dye so trying to squeeze it from the bottle once mixed is hard work so next time I will put it in a bowl mix it and use a brush. The colour came out even all over and my hair didn't feel dry after so I'm happy that I am not doing damage to my hair. Highly , highly recommend this dye it is the best!. Update after having washed it 3 times , the colour has faded but it's still really vibrant and such a beautiful colour. I did find that the colour faded a lot more quickly than other permanent hair dyes do , as the vibrancy normally lasts a lot longer with other brands , but it faded to a nice lilac colour after about 6 washes , I wash my hair once a week for reference, so if you wash your hair more often then the colour will fade a lot quicker.

Super
Easy to use. The color is great. I used to dye another hair dye but it's no longer on sale, I was looking for hair dye for a long time to make my color suit me until I found this one and for three years I've only been using it like the Red Hot producer writes my color 😁

Awful
Don't bother, nice and purple when done, after 1 wash it turnt reddish plum and after 2 washes now red, its definitely not permanent and a waste of money

Not yet sure about it
Unpacking: The box comes with gloves and the two colour components. No after treatment, no plastic head wrap. Odd, but nothing a cut plastic bag and my usual conditioner cant sort out. Application: Straight forward on dry hair. Oddly enough the colour did not change when the two bottles were mixed or when it was applied to my hair. Colour performance: First of all, my hair is white now ( previously blonde). This means it normally soaks up colour like a very thirsty person in a desert, but alas no permanent colour stays permanent. They all wash out after two weeks, the cheap or the expensive ones. The result here was...faint. Not at all like in the picture. The colour was true, but more like purple haze than purple rain. Gentle. Delicate. Barely there, but still noticeable. Not at all unpleasant. Just not what I was expecting or hoping for. I fear it will wash out pretty quickly, but for a once in a while booster for a special occasion, why not. Overall hair: This was the biggest, most pleasant surprise. I just washed the hair afterwards without any conditioner or mask, yet my hair was shiny, silky and soft. Easy to combe, looks and feels undamaged. Will probably buy again. As a special treat. Just dont expect to get what the picture promises.

Beautiful but fading fast.
It was my perfect purple shade but only for the first week or two. After that it's washing off and fading. It's still purple but not as vibrant. What a shame it was not lasting longer. Otherwise it would be my number 1 hair dye.

A Radiant Transformation
My purple hair looks absolutely stunning! The multi-tonal shades give it a vibrant and eye-catching appearance. Whether you’re rocking this color for a special occasion or just because, it’s clear that you’ve made a bold and beautiful choice. Keep shining with that radiant purple! 💜🌟. I recently tried this best purple hair dye on the market, and I am absolutely thrilled with the results. Let me share my experience: Coverage: If you’re like me and have some pesky white hairs, this dye has you covered—literally! The coverage is superb, seamlessly blending those stubborn strands into a vibrant purple canvas. Color Brilliance: The moment I rinsed off the dye, I was greeted by a burst of color that left me in awe. The shade is not just purple; it’s a wonderful, luminous purple that catches the light and turns heads. I was complimented many times for my hair. Long-Lasting: It’s been weeks since I dyed my hair, and the color is still as intense as ever. No fading, no dullness—just pure brilliance. In summary, this purple hair dye is a game-changer. Whether you’re looking to make a bold statement or simply want to refresh your look, I highly recommend it. Say goodbye to lackluster hair days and hello to a radiant transformation! Rating: ⭐⭐⭐⭐⭐ Exceptional Service and Generosity I recently had the pleasure of interacting with the seller on Amazon, and I must say that their customer service exceeded my expectations. Despite a minor hiccup with the initial order delivery, they went above and beyond to make things right. Not only did they promptly address the issue, but they also surprised me by sending a second order as a free gift. Their gesture of gratitude for my continued patronage was truly heartwarming. The seller’s communication was impeccable throughout the process. They were attentive, understanding, and genuinely committed to ensuring my satisfaction. It’s rare to encounter such dedication in today’s fast-paced world of online shopping. I highly recommend this seller to anyone seeking exceptional service and a touch of generosity. Thank you for turning what could have been a frustrating experience into a delightful one. I’ll definitely be coming back for more! Rating: ⭐⭐⭐⭐⭐

Great coverage and true color
I used Black Saphire. My hair was only colored with a non permanent pink and purple which only took at the ends. So basically I had medium brown with magenta ends. I wasn't sure how this would turn out. I've never done such a dark color. I usually lean blonde or red. But I love this. This colored very evenly. I was also worried it would be more blue than black but I was pleasantly suprised that I got exactly what I wanted...a black with navy blue hue in the light. I can't geek you how long it will last as I only wash my hair about every 10 days. So for me it will last forever lol. I will definitely buy again as I'll keep this color for a long time since I love it so much. I wish I world have tried this years ago lol

Vraiment au top!
Je modifie mon précédent commentaire après avoir fait ma coloration qui est très réussie! Joli gris métallique, ne fais pas "vieux", couleur éclatante et même rajeunissante! Je comprends pourquoi il n'y a pas de soin dans la boîte : le produit est très doux, mais si vous avez les cheveux secs comme moi, un après-shampoing suffit. Je recommande ce produit les yeux fermés, il ne brûle pas le cuir chevelu comme les autres! Merci pour cette découverte!

Excellent product!!
Works great! Wasn’t an overpowering smell. Easy to follow instructions and easy to mix. The one negative is it only lasted about 6! weeks but it is a problem with most dyes when trying to dye darker hair.

Just wow!
I used this and omg. I never had a hair dye that has kept my hair so naturally soft and shiny. After the initial wash, my hair hasn't leaked dye, and the smell is not chemically. I am addicted to this product. Plus it really did cover my white hairs. RECOMMEND.
