Review: Excellent dye - Dont normally do reveiws but felt thos deserved one.beautiful colour dont worry looks very dark at beginning.this was a rich thick creamy product.no smell.and plenty of it.no conitioner in box and usually my hair is knotty after dying no need for conditioner...it left my hair silky smooth and able to comb it and bear in mind I hv curly hair I would buy this again in an instant
Review: 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 desertcart 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.

*by A***A on 8 July 2026*

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 😁
