I've been dyeing my hair black for about 3 years now so I've tried a lot of dyes in that time but, out of all the "blue black" dyes I've tried, this is the only one that actually does what it claims to. My hair is thick & the majority of it hangs past the base of my spine but one box is more than enough to cover my roots & top-up the lengths as well.

My roots creep up on me every 2-3 weeks & I previously used "DermaV-10 0.1 Black" on my roots then "Feria Starry Night" on my lengths but, one time, my roots were particularly bad, my blue hue was fading & I had no time to go buy another dye so I applied this all over & hoped for the best. It worked so much better than I could have expected & I've been in love ever since!

I like to dye my hair once in a while with different colors but the color I'm always into is black so when I get tired of the light color I have I always go black for months. I always buy the L'Oréal brand in any shade. But I mostly love the black shades because it will work to cover any color I have. And actually fully covers the color not like other brands I have tried. The product is not as watery and doest drip like others, my whole family trust L'Oréal is the brand we love.

I have very mixed feelings on this dye. I use both professional and boxed dyes to keep my hair black and vibrant. I have never used loreal starry night so I gave it a try and was surprised at how blue the dye is. Go8ng on the color was a rich royal to navy shade and I did.do an all over color since the length of my hair was fading. After my length is a gorgeous renewed black bit my roots are definitely blue. Also the conditioner has glitter in it which I personally do not enjoy. I actually like the definitely blue tone to my roots which is a unique loom but I do not recommend this c9lor if you are looking to go a deep black.

Everyone asks what hair dye I use for this head of hair and this product is always the answer. The blue/black tint that this hair dye leaves is so freaking pretty especiallllly when the sun hits it.☀️ Everyone thinks that I go to the salon for this color but I just dye it at home while watching Netflix (no ones got time to go to a salon). I have used the EXACT same hair dye since my freshmen year of high school (YIKES!) and I still use it to this day. Ugh I just love this hair dye so M U C H! 💕

This had a good black color when I went black a couple year ago. IT got over everywhere and I used multiple layers of gloves out of fear of being dyed. IT works great, however, I can not compare the black dye to other black dyes in the industry since I only dyed my hair black once.

I love this hair dye so much. It has a blue tint to it that shines bright when you're caught in the sun. The smell is horrendous, but most hair dye stinks! I also love the little conditioner they put in the box! My hair is always silky and shiny after using this dye.

I used it to dye my hair black and it works pretty well. It’s still black. It’s been black since like October 😂 so that’s nice L'Oréal Paris Feria Permanent Haircolour Gel Bright Black 21 Cooler

I'll admit it, I'm cheap. When I first started dying my own hair I went to Sally and bought a few different items to try out. Why pay a salon $80 when all I want is black hair? The first dye I chose gave me a strange allergic reaction, so I was scared to try anything else. I asked a few friends and one suggested Feria for black color that she had been using for years. I picked up a box, and after spot-testing, I dyed my hair with no allergic reaction! And I've been using it ever since. The kit comes with a pair of gloves.

My only issue is that I wish there was more product. I have long hair, but nothing out of the ordinary, and I really have to stretch the bottle to cover my hair. Buying two boxes would mean wasting 85% of another box of color.

The color is vibrant for about a month and solid for about three. After that it begins to fade pretty quickly. My base hair is medium brown, so my hair sits at dark brown until I dye it again.

I plan on sticking to this color because it works well and it doesn't make my throat close up! Thanks for not killing me, L'Oreal! You're the best!

This is my FAVORITE, most used hair color. This blue/black shade is my absolute favorite-its enough dark black to be "normal enough" for everyday work life, but has an AMAZING bright blue undertone that is deep and bright enough to make it give my hair a funky edge i like. This color formula is awesome too, it comes with a developer, cream and conditioner. The developer doesnt have a strong chemical smell and there is no ammonia. The after dye conditioner smells wonderful and works AMAZING to make my hair feel like silk when done. The grey coverage is great(even covers my pesky front greys that are impossible to cover.) And the over all color is "multi faceted" and very dimensional so my hair has great coverage and "movement". I LOVE this hair color. It is one of the more expensive colors so i sometimes switch to others to try but I always choose Loreal as my top choice and this is my favorite brand and color pick!
