Special Effects SFX Hair Color Hair Dye

I used Blood Red on chin length hair shorter in back and barely used a 1/4 bottle. I took all precautions and suggestion on various websites if you google beeunique you can find UK website that has all kinds of tips.

Preparation:
Always do a strand test! Less surprises and you can adjust the color if you don't like it. I did mine 3 days before so I could see how washing effected it. They suggest snipping a strand I chose a small portion of the underside of my hair.
It looked good but in the end it was still a little much after I did my whole head.
My hair was a mix of natural light brown regrowth and strawberry blond from previous permanent hair dye.

Prepare the Blood(y) Red scene!

I dyed my hair with the nuclear red and it turned out great. I bleached a few streaks to really make the color pop. I describe the color on the bleached parts as a neon red. As it washes out over time, it fades to a neon orange and then to a peach-ish color, both very aesthetically pleasing to me and I actually let it go through the color change before re-dying it.
And yes, the color (nuclear red at least) DOES glow under blacklight.

I used blue mayhem, and it was great for the first few days. I had a lovely shade of blue that really popped, but within 2 weeks of washing my hair about every other day (using my regular shampoo, which is not specifically for color treated hair) it was almost completely gone and what was left just appeared a dirty gray color that was completely unattractive. The product states that it lasts 3 to 6 weeks and if all the dye works as the blue mayhem did for me then the only way I could have gotten close to 6 weeks would be to wash my hair once and week. I was somewhat disappointed, but I was only looking for temporary color. If you're looking for dye that you can you can use for a party or special occasion type event that will wash out fairly soon I would recommend this product, but not if you want it to last the fully 3-6 weeks without reapplying.
