Dirty Mermaid is a stunning seafoam green that will make your fantasy hair color dreams come true, and its sugary citrus vanilla scent will make your transformation even sweeter!

  • AMAZING hot pink!!
Color: Juicy (Fuschia)
I have 1 year grown out ~recession blonde~ balayage highlights and darker blonde natural roots that I am having a hard time accepting lol so I got bored and tried this and the Juicy (fuschia hot pink) color turned out so great on my hair. I've gotten tons of compliments and no one can believe I did it at home without bleaching first. I leave it on for at least 1-2 hours before rinsing. Smells amazing and does not damage hair! If you have virgin hair it will wash out a bit quicker, on my highlighted ends it definitely soaked up and lasted longer. Pics of my hair before, right after rinsing and air drying, and 2 months out from first use. I wash 1-2 times per week with a nice shampoo (Pureology hydrate) and it seems to make it last much longer. It fades nicely into a lighter softer pink over time. It may stain you counter so best to put down some newspaper. didn't stain my white shower/tub but I kept some bleach spray handy just in case, I'm sure other showers may differ. I purchased a cheap bowl and brush and some pink gloves and disposable hai plastic caps to put over while letting it process on my head. ... show more

  • Fun colors without the damage
Color: Juicy (Fuschia)
I love this brand of hair dye. It is definitely semi-permanent. It’s not as vibrant if you don’t have platinum hair, but if you don’t wash your hair with shampoo every time you can stretch it to last longer . I have been using the pony color for over a year and love it and we try juicy for my daughter that has a strawberry blonde hair and it looked really cute on her without damaging her hair but I love about this is it’s not going to damage her hair, but allows her to have the fun of the color for a month or so ... show more

  • Love it!
Color: Mystic (Electric Blue)
I usually use Rockabilly Blue but I've had good results with this brand in the past so I went with it this time. With this color works just like most of them do, the lighter your hair is the brighter it is but no matter what color you start with it does hold well. To get the color on the box your hair will need to be bleached white, otherwise it holds just as well but it gets duller & darker as the hair gets darker. I am predominately a level 8 but some tones are lighter some are darker because my last bleaching went bad and I do have a little gray in with natural brown roots so when I use unnatural colors it gives me an amazing variety of shade variation. I got a range of colors anywhere from bright bright blue like in the picture to a duller darker blue to a bluish overtone over my natural med. brown color that stands out like a blazing blue overcast in indoor lighting or outside. It's deeply pigmented and very comparable with Rockabilly but one big bonus, you get more because the bottle is much bigger so that earned it 5 full stars. My hair is still a work in progress and when it's finished I will be back to post results but so far it's downright amazing & I am very happy with this brand & this color so I decided to stop & order a couple more colors and get a bit more creative. It smells great and I'm happy with the product, the price, and the results. I like to put mine in then wrap it in saran wrap and set overnight & shower it out the next morning. It leave the hair super soft, smelling good and in good overall condition and doing it this way with 1 wash a week it lasts an amazingly long time. When mine arrived it was a bit runny so I suggest stirring it with something plastic before use to thicken it back up. I will update with a pic & final results when my other colors have arrived & I'm finished coloring. *If this review was Helpful to you please let me know!* ... show more

  • Easy to use, conditioning, very pigmented.
Color: Genie (Deep Violet Purple)
I would purchase this again. I used the color "Genie". Easy to use, conditioning, very pigmented. I have a good amount of grey hair- it covers the grey pretty well, but fades from the grey very quickly - faster than the rest of my hair. It fades to lavender though, so its pretty still. Like all direct dyes, this will stain everything. Use gloves and an old shirt and cover all surfaces. Wipe shower walls down immediately. You get the picture. ... show more

  • YESSSSSSSSSS
Color: Anime (Candy Blue)
YESSS, Yes AND YES! LOVE LOVE LOVE THIS HAIR DYE. Some of my hair was already pre lightened (fading purple color) and not all of my hair is dyed, but by my face it is. Brought this to my stylist. She loved this smell and so did I. Literally it smells soooo good. I am obsessed with how my hair turned out. For reference I have 3A natural curls, but had her blow dry it out straight (so I could see how long my hair is). The dye is so pigmented and I’ve washed my hair over 7 times already and there’s no fade what so ever. I’ve had allergic reactions before to various dyes (Overtone, Keracolor conditioner) and this brand uses great ingredients and my sensitive skin loves it. I literally have no complaints. Yes my hair bleeds a little when I wash it (which is every other day), but the color is just as vibrant. I’m so impressed with this dye. ... show more

  • Nice but doesn’t last
Color: Neon Peach
Love, love , love how easy this is to use and the easy clean up. However, the first time I shampooed a few days after coloring, the color faded right out. I had processed it for 35 minutes, and it looked great - not super bright, but I wasn’t looking for that. But after two washes, the color is barely visible. My goal is to color some gray and have an overall fun hair color without damaging my hair. ... show more
