Description

Blue Moon Blue Moon is a bright, cool true blue dye. For the most vibrant results, we recommend lightening hair to a very light level 9 blonde or lighter, and toning hair that has yellow tones before use to avoid undesired hues. 1. Wash hair with a deep cleansing/clarifying shampoo. Do not condition. 2. Dry hair with a blow dryer to make sure the hair is extremely porous. 3. Put on gloves and apply Manic Panic Hair Color using a tint brush making sure hair is thoroughly saturated. 4. Comb through the hair color to make sure it is evenly applied. The cream may become slightly frothy. 5. Cover hair with a plastic cap and leave on for 30-45 minutes. For more intensity, add heat. 6. Rinse with cool water away from your face and body until water runs clear. Do not shampoo. 7. Style as desired. To prevent color transfer or bleeding, always make sure your hair is completely dry. Pro Tip: Use a hair dryer to evenly apply heat for 5-10 minutes of your processing time. This will help to open up the cuticle and allow the Manic Panic hair color to better penetrate the hair strand. Make sure to allow the hair to cool completely before rinsing out color.

  • WOW Color
Color: Blue Moon Size: 4 fluid ounces (Pack of 1)
A beautiful dark blue color that goes on smoothly and easily. I have medium dark hair so I bleached before applying. (I used Manic Panic's Amplified Bleach. If you are doing a lot of hair, or your hair is long, I would get 2 bleach kits if you are using this particular brand.) Manic Panic is easy to apply - just apply the color where you want it, leave it (I left it for about an hour), rinse out. And rinse out. And rinse out. lol Expect to turn your towel blue - for the next couple of washes. The less you wash your hair, the longer it stays. After a few washes, this color will turn a light turquoise color. (Still pretty.) Right after coloring, be careful - ANYTIME your hair gets wet, the color WILL run. (It will also get under your nails when you scratch your head.) These minor annoyances don't bother me enough to stop using Manic Panic...but I would want to know this stuff before I used it. Bottom Line: Manic Panic is the BEST product out there for coloring your hair funky shades. It lasts much longer than any other brand I've tried, it's easy application makes re-touches "cake", and the colors are bold and brilliant. I wouldn't hesitate to use this brand, or color, again. ... show more

  • Love!
Color: Blue Moon Size: 4 fluid ounces (Pack of 1)
Love this shade of blue. It's definitely cheaper to order it on here not in the 3 pack and instead just buy 3 separately. Don't be fooled. It does stain the bathtub/towels the 1st and 2nd wash so be careful.

  • I gave it a shot and it went well.
Color: Blue Moon Size: 4 fluid ounces (Pack of 1)
I am a Joico dye loyalist. Manic Panic and every other dye never crosses my mind, I want my Joico dye or bust. It just works for me and never fails - but due to the pandemic Joico dye is in short supply and I could not find the blue I wanted. So I was forced to go with Manic and I don't really regret it. I used half of a jar of Blue Moon diluted with 3/4's of the amount of conditioner to get the look I did and left it on for about three hours. It is very vibrant I will admit, my hair doesn't feel weird like with other dyes (looking at you splat) and hasn't bled too much. However it's just not as vibrant as Joico is, so I miss that extra luster that Joico has. It also still noticeably bleeds a lot more than my prefered dye, and my pillow is rather unhappy after sleeping on it even with dry hair for the last week. It looks good, went well and works but, I think I will be going back to Joico when they restock. ... show more

It was a bright, vivid blue color that stayed in my hair for quite some time, although it did keep fading.
