One 'n Only Perfect Intensity Midnight Blue Semi Permanent Hair Color Midnight Blue

I relax my hair, so semi permanent is my only option. This is the first time I’ve used this color so I tried it on dry dirty hair and it did great! This is even after I used Shampoo and conditioner (because again, my hair was dirty )Great vibrant color deposit. Does not dry hair Minimal bleeding/transfer and if it does bleed it washes away easily. I have used many semi permanents, this one does not take weeks to wash alway from tub/shower. Regular cleaners worked fine; I didn’t need nail polish remover.*I will update in a few months when I have to re-relax my hair and then I will color my hair again to see if I get even better results.

This was a great buy and it stayed in so long before it began to fade. My son wanted blue and we'd already struck out with Manic Panic. So we applied this onto his already bleached hair and it was comic book Superman Blue. It lasted over three months before it faded and paled out to a Turquoise-Pastel greenish-blue color. I would say my son got about five months of color out of this and about 3-4 of those months was the midnight blue.

Really good color not as dark as I had planned but it still looked good so far is lasting really good

Dye is super strong.. stained my skin for days. Every time i scratched my head my fingers would turn blue. After 2 washes, it’s turning teal. I’m not going to be buying this brand again

The color did not wash out and nothing covers it I have tried so many different ways but still no difference

I love that this dye it gentle enough to be Curly Girl Method Approved (no silicone, sulfates, wax or mineral oil) and it did dye over my medium brown hair without any bleach for a low light effect I wanted. But, it’s NOT midnight blue! It’s Teal Green! I will use it again and try different colors but I really did not want green hair, lol

This stuff will not come out of my hair. It is very a very vibrant bold blue.

I'm extremely happy with this purchase. It was easy to apply, since it didn't need to be mixed with developer, and it felt very gentle on my thin, damaged hair. The instructions say to leave it on for 30 minutes, but because I didn't bleach my hair first I left it on longer. I'm going to be lazy and copy/paste my answer to a product question into this review:----I used it on my much-processed hair. I'm naturally dark blonde but for many years dyed it golden blonde or light amber. I haven't used those dyes in 2+ years, but the bottom half of my (very) long hair is still reddish-gold compared to the natural color that has grown in. I used Midnight Blue and Lilac Purple. I got deep, rich color from the Midnight Blue after leaving it on for 2 hours. After leaving the Lilac Purple on for 4 hours, it was hardly noticeable except in bright sunlight. The richness of the blue lasted about 3-4 days (shampooing daily) and then slowly faded to a light greenish blue which was actually quite nice looking. I did the blue streaks 10 days ago and touched up a few of them 2 days ago. The ones I didn't touch up are still the light greenish blue, almost pastel now. Again, I quite like the color it has faded to. Against the deep blue it's almost like I used two different, complementary colors.----I'm going to purchase the Midnight Purple next, and based on my experience with the Midnight Blue I'm sure I'll get the purple color I was looking for.
