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.

It works amazing
I read good and bad reviews. Mine is good is have quite a bit of silver hair and is nice and purple now. The rest of my hair is dark brown and is has a very nice purple tone. My husband used it to and his silver is not covered as well but his light brown hair looks quite purple. I believe it depends on hair porosity.

ONLY LASTS A COUPLE OF WASHES!
I purchased two of these at the same time,but sadly won't be buying anymore. The colour turns out to be l9vely and vibrant and I loved it when i'd first used it. Unfortunately it completely washed out after only a couple of washes.I tried the 2nd pack i'd bought thinking maybe I hadn't applied it correctly or something(slthough I'm accomplished at hair dying)-but exactly the same thing happened,despite my using speciality shampoos for dyed hair. I was so upset by this as I loved the vibrancy of the colour,but since i'd paid nearly double what I usually pay for my usual "off the shelf"dye,I expected it yo have lasted for more than a week.It wasn't that it gradually faded either,it just completely washed out. I contacted the company's customer service to explain my issue,but I didn't find their attitude to be very accommodating. Firstly they implied that I may need to use more than one pack at once for longer or thicker hair,even though I explained to them that I had medium to fine short hair!. They then suggested that I purchase some of their temporary treatments to use alongside this supposed "permament"dye to maintain the colour longer-which I found to be a insulting suggestion as this one lasted so poorly,I doubted a temporary colourr would fare better. It's such a shame as like I've said the colour initially comes out beautifully vibrant and I loved it.However,i'd definitely recommend to anyone looking for a purple type colour to just stick with the better known brands that have a far cheaper price and definitely more longevity.

Lovely soft colour and silky condition
Really nice hair dye, good coverage with 1 bottle, gloves were a decent size as my hands are quite big!! I would say the colour didn't cone out bright purple, as I have dark brown hair, but none the less it's quite a nice colour. And made my hair really in nice condition. Would recommend.

Beautiful colour but might not last long
I absolutely adored this colour but had to bleach before hand which made for slightly brittle hair but I wanted the full colour. The formula worked well on my dry, wavy hair and 2 boxes did the job. It’s definitely on the pricier side of dyes but this colour with the addition that it’s permanent made it a good choice. My hair already struggles with absorbing colour so unfortunately it didn’t last long but it’s a beautiful colour and attaches nicely to lightened hair. I would buy again but for maintaining the colour it’s a bit too much for me

Does last after washing?mot cover the white roots
I’m buying this brand for the second time. The colour itself looks very nice.But Doesn’t Not cover the grey/white roots!!!! However it’s very hard to use the mixed container,it’s just stuck and you need keep outing the container or even open it and ad some water so it’s can get trough. Very bad packaging,it’s can be used straightforwardly. Also,it’s not fully cover the white roots and although it’s says that’s its permanent,it’s not last til next wash! The colour is nice but..,

Bright purple hair 😍
This worked better then I thought. I had bleached my hair the same day and then use this and I have bright purple hair which doesn't quite show in the picture. It's a bit to bright for my liking but I am pleased overall

Vibrant
I've used lots of different hair dye brands in the past. This one is by far the most vibrant! Lovely to put on, fast develop time and easy to wash off, despite the vibrant colour it did not stain my head like other have done. Will definitely be buying again!

I have previously had my hair dyed red by a professional, but being unable to get to a salon again during these times, I took the chance to touch up my hair at home. I also decided I wanted something more orange-red than the dark-red I had. This is definitely a bright orange shade, but after a few washes fades down a bit. I love it and have already ordered again.

I have very light blonde hair (almost white) and I followed the instructions to the letter and I didn't get any colour al all - complete waste of time and money.
