For best results, particularly with lighter shades, apply to hair that has been pre-lightened to pale blond. Apply to freshly washed (not conditioned), dry or damp hair. Apply using latex gloves. We recommend using a tinting brush to ensure even coverage. Work the dye into the hair for a few minutes and leave for at least 15 minutes (you may leave this dye on for longer as long as you cover your hair with plastic wrap or a shower cap to prevent it drying out). Rinse with warm water until the water runs clear.

For longer lasting colour, use a shampoo and conditioner for coloured hair.

  • Precautions

    Although these dyes do not contain the harsh chemicals of other dyes such as ammonia and peroxide, there is still a small chance that they could cause an allergic reaction. For this reason it is imperative that you do a strand and sensitivity test before using them. An ingredients list is available above and can also be found on the product’s packaging (ingredients list can sometimes be found under our sticker). NEVER use any of these products on eyelashes or eyebrows.

    As you would expect from a dye these colours can stain textiles, ceramic, wood and other surfaces as well as temporarily stain skin and nails so be careful to cover surfaces and wear gloves when applying the colour. Once used these products may also rub off your hair and skin and onto clothing and bedding. Although this usually disappears after washing it’s worth bearing this in mind. Staining to bathtubs, basins and showers can easily be cleaned using a bleach based cleaning product.

    Do not mix with peroxide.

    Colours may cause permanent staining to bleached or chemically treated hair. Tip: You can avoid staining on your skin by applying a layer of vaseline anywhere on your skin where dye may come in contact.

Reviews of Special Effects Nuclear Red

  • The color is extremely bright and very beautiful. I applied it over bleached hair that was a pale blonde. After a few washes, however, it began to fade to an orange. If I had washed it every day for as long as I had it, after a week to two weeks I would have ended up with a very pale orange with some streaks of pale blonde. While the color was its brightest I got many compliments from random strangers, a lot of looks, and even a few people hitting on me =/ I only washed my hair once a week so that it wouldn't wash out too quickly (yeah my hair got pretty greasy since I rarely washed it). No one gave me any bad comments. Overall, it was very fun to have nuclear red hair. The only reason why I'm giving it four stars instead of five is because of how quickly it washed out. But if you're willing to re-dye it once a week or once every two weeks then you shouldn't have a problem with it.
  • An excellent dye for natural hair. A really hot hot ornage red. this faded to an equally nice ornage on my hair and didnt stain as badly as a lot of SFX dyes.
  • Gorgeous red, very vibrant.
  • This red has amazed me. I put it over barely faded Electric Blue, hoping to god it would come out purple and it didn't! It's a little darker on my hair because of the previous color, but my roots are the bright red it should be. I am giving it a 4 only because I've only had it in for a week, so I don't know how it will fade. So far it hasn't faded at all.
  • A bright and beautiful red. I'd say it lasted a good 2-3 months and faded to an orange that kind of lingered in my hair for another couple of months.
  • Good color, nice and solid. Medium fading. Stained a little, but I managed to get most of it out eventually when I wanted to change colors.
  • This was my favorite dye that I've used. It lasts for months with hardly any fading, and even when it does fade, the color doesn't turn gross.
  • I chose this color for Halloween as my hair is black and I've kept a blond streak at the front for years. I wanted to jazz things up, so I hit up my daughter for some of her hair dyes. Hubby was wearing black and red, so I chose the red, instead of blue (which my son wanted me to do. lol) I put the Nuclear Red in about 2 days before Halloween 2010, and as of the first week of April, there are still small remnants of the color (slightly orange) on the blonde. I don't recall just how long that I left the color in...I'd guess it was my normal one hour. I wash my hair about once every 5-7 days (one clarifying shampooing, one moisturizing shampooing, then conditioner) unless I've gotten really grimy before that. The color stayed STRONG and bright far into January and started fading first at the tips (oldest bleaching) and slowly towards the roots. During this time it still looked awesome and I got just as many compliments on it as while it was fully it looked like fire, with the yellow to reddish orange fade. I do have to say that the first 3 or 4 days I couldn't stand the color (not the color's fault), because it was so extreme and bright, but it QUICKLY grew on me, as soon as I discovered that for the first time in my life, red lipstick looked GREAT on me!! I've been discussing which color to go with again for the last week and hubby let me know that he couldn't stand it at first either, but then also fell in love with it...and wants it this color again...not blue. lol If I knew that I could put in other colors and have them NOT last as long as this did, I'd try them just for a change of pace...but I have a feeling they'd hang around just as long.
  • Love this colour! Perfect bold attention striking traffic stopping red! Gorgeous and bright even on orange shade bleached hair!! It doesn't even stain like crazy. It is a fake looking red but if you want that bright bold red shade, then go for this !
  • This is favourite colour ever. i just keep going back to it. as it washes out, parts of my hair seemed to stay red while others went orange and others went yellow. it was like getting free highlights LOL I really really love this colour.
  • This is a wonderful energy delivering Red! I like nuclear red and blood red from special effects!
  • This is the color Ive been looking for!!!!
  • Fantastic Fluro red, very attention seeking red :) Love it and it did last for ages. I always top my red up each wash with the colour dropped into the conditioner jobby but even so it stays vibrant. Yes it does stain if you get it wet or sweat when you sleep your pillows will be stained. Its worth it though for such a fab colour.
  • Nuclear Red was my first real foray into unnatural color, and I *LOVED* it. I would go back to this color in a heartbeat. I'm a natural redhead, and didn't bleach my hair before dyeing -- the color still came out brilliantly red! Letting this dye sit for a while is your best bet for truly vibrant color; the longer you let it sit, the better it looks. I did experience an amount of disappointment in how quickly it faded, but only because I loved how it looked when I first dyed it so much. The fade is actually very subtle and cute -- a very nice orange-y color -- and touch-ups every 3-4 weeks will keep you looking more nuclear than Chernobyl. (Oof... too soon?)
  • My favourite shade of bright red so far - and I've tried a few! I'm delighted with this dye, it's as bright as you can go without going orange or pink. Needed less half as much of this as I needed when using other brands of dye, so it turned out to be very good value for money. I've had this colour in about a week and not a hint of a fade so far. It being bright red I do expect it to wash out fairly quickly though! Downside? A lot of bleeding and staining of fingers, even if you wash your hair in cold water with no shampoo. But that's so worth it for the vibrancy of the colour.
  • Quick update to say the fade on this is gorgeous! If you've ever used a red highlighter pen (rather than a pink one), that is what the fade looks like. Which I love almost as much as the original colour. I've just upped my rating to five stars because I love it so much I'm getting anxious that HairCrazy has run out! Oh, and the claim that it's UV reactive? Tried, tested and true. Looks neon pink and FABULOUS! Admittedly it doesn't like to come out with colour remover (I've had a much easier time with Directions and Schwarzkopf reds), so if you want a change of scene you'll need to be pretty determined. I'll be back to this colour before long. Officially my favourite of all the reds I've tried (and there have been many!).
  • This is red I've been looking for! I've always loved red hair and I've always wanted it super bright. I've tried lots of dyes from lots of brands, but nothing ever came close to this. I'm so glad I decided to give Nuclear Red a try, because now I have the hair colour I've been looking for for over five years! Amazing vibrancy. Amazing formula. Leaves my bleached hair looking shiny and healthy.
  • I used this over unbleached medium brown hair and it turned out crazy bright. It was amazing. It was so bright most people didn't know I didn't bleach my hair before applying it. It stayed very bright for the 2 or so months I kept it. For me, the orange tones started to fade out and it became a more true red. I highly recommend it on unbleached hair.
  • This is the dye to go for if you want to perfectly emulate the hair colour of Ariel in the little mermaid :) a crayon-bright red with no visible pink tones at all. Made my hair super shiny and soft and gave great evrn coverage of a hotpotch base - including chunks of atomic pink. Theres a little shower run every time I wash my hair, but the brightness hasnt lessened at all. I havent had the pillow staining problem others have mentioned. Lovely dye!
  • Lovely bright shade of ornage based red but it’s very very true red
