The top layer is blood red and middle layer is purple from blending the two. The blue color came out exactly as expected and hasn't faded after several weeks.I've been doing unnatural colors for over eight years now and would like to clear up a few bad reviews. Pre-bleaching is a part of the process. If you don't bleach, don't complain about the product for your choice not to. If you want the color to last, wait a day after bleaching so it's completely inactive, and keep the color on for at least a few hours. The more you wash your hair (especially shampoo), swim (especially in water with chemicals), and even extended exposure to the sun will affect the rate it fades. I can usually keep good color for at least a month. Even when they fade, the way I color blend just looks like it's supposed to be pastel colors. I don't know what others are talking about hard clean up. Out of all the brands I've used this is hands down the easiest to clean from my skin, surfaces, and especially the tub. So far I'm loving this brand! ### ⭐⭐⭐ Faded faster than expected.... *by M***K on March 1, 2012* I was pretty bummed that blue mayhem faded like it did. I bleached my tips and did parts of my hair atomic pink and others blue mayhem. The atomic pink has not faded at all in two months and I love it! The blue mayhem has required several touch ups that don't hardly last a week. I know blue is a hard color to keep bright and vibrant, but with the Special Effects reputation and my success with atomic pink, I had higher hopes for this color. I'll probably not buy it again and use a bright purple instead. ### ⭐⭐⭐⭐⭐ Blue Mayhem - Back to my roots. *by L***N on July 27, 2016* Recently I have been on a journey to find a better hair dye than Special Effects.I have been using Special Effects for 13 years, I thought it might be worth some investigation. I have found that I really started out with the best (Special Effects) and it perhaps spoiled me into expecting a lot out of other dyes.Special Effects tends to "heal" some of the damage I do when bleaching. I notice my hair feeling smoother after using it post bleach. Because it is a deposit dye, the longer you leave it in, the better it will soak into your hair shaft. After leaving it in 6 hours and washing it out, it hardly bled.I think this is what I was looking for- a way not to have my bathroom look like I murdered a care bear once a month or so. Leaving it in a long time, rinsing it out with cool water and following up with Olaplex no.2 really has increased the longevity and brightness, and cut down on the bleeding.I am following up once a week with Olaplex no. 3 for overall health of my hair and it's been nothing but positive.Give this a shot if you are looking to dye your hair fun colors that remain vivid and healthy. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1376318-special-effects-semi-permanent-hair-dye-blue-mayhem-4-oz](https://www.desertcart.pt/products/1376318-special-effects-semi-permanent-hair-dye-blue-mayhem-4-oz) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-16*
