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.

    • one day i'll go gray and probably (maybe) feel like I HAVE to dye it
Color: Blue Moon Size: 4 fluid ounces (Pack of 1)
So I was iffy on buying this. I haven't used any kind of color on my hair for, wow, several year. I used to dye it a lot when I was younger, then around thirty I decided, hey, one day i'll go gray and probably (maybe) feel like I HAVE to dye it, so why not just wait till then? For the record, my hair has been blue before (long ago, in a lifetime far far away). Also, everyone (when I was younger) told me how pretty my hair was, and how much money other people paid to have highlights like that, blah blah, the point is, haven't used any color for years. Anyways, I have very dark brown hair with some natural red highlights, now i'm in my early 40's, no greys yet (yay me!) but kinda bored with myself and life, and blue is my favorite color. So. I didn't expect this dye to do much on my color, especially since I wasn't really interested in bleaching any part of my hair first (I know the color would last more, but I have very long, waist length hair, and I'm not really interested in having to cut any of it off because of dryness, breakage, etc.) OK, so I did some random streaks, full length and, it worked! I was totally surprised (and thrilled). The color is more of an indigo than dark blue, I guess, but really, I don't care, because it worked, and now it's been a couple weeks, i'll have to do it again if I want to keep it up (not so easy for my profession). Anyways, i'm thrilled with this, I'm actually shocked on how well it worked on my dark hair, which is once again, not black, but a very dark brown. No complaints here, you will have different results if you're hair is blonde or you bleach it first, but even for true brunettes, it does work! ... show more

    • The O.G. punk hair dye- women owned.
Color: Blue Moon Size: 4 fluid ounces (Pack of 1)
My kid finally wants to go the way of his mom back in the day. But he keeps trying to use all this drug store crap that never lasts, is expensive and in some "salony" type form. Finally, I did what all good moms do, "just let me do it." Manic Panic- smells decent and has all the best colors for your nuanced individuality needs. Mix and Match if you want. You don't need a brush or squeeze bottle because those are for p**sies. Put your gloved hand in a jar and get it done. Of course it comes off everywhere because that's what happens. The more intense the color, and the longer you leave it on, the more staying power you will get. Sleep in a shower cap with it on your hair if you have to. Have your hair dye only/dog towels at the ready and rock it out like your grandma did when M.P., Special Effects, and P.C. were your only alternative to drained magic markers.! Manic Panic will be around longer than the corporate giants dipping their toe into the preteen unicorn market because, like almost all of their dye colors, they have staying power. ... show more

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.
