Review: Absolutely amazing colour. I have used many many blues and this is by far the best. A vibrant shiny blue to even yellowey bleached hair, does not fade hardly at all, mine lasts a brilliant blue for about a month then goes to a slightly less strong indigo colour. go SFX! -CreepyGreenLight-

Review: Electric Blue is the best color I have used so far. I applied it to brown hair with gold highlights. It was very vibrant, even on the brown base. It did not fade quickly. Even when my hair faded back to brown, I still noticed quite a few stray blue strands. It has incredible staying power, relative to the lighter blues. I recommend this color to anyone who wants a deep vibrant blue that will stay, no matter how dark their current color is. -Violet-

Review: I used this color on unbleached hair and loved the result. My hair is naturally light brown with a yellow base, so I was worried about it coming in a little green. I was concerned over nothing, though. I got a really rich navy color with streaks of bright blue where my hair had been lightened by the sun. Really fantastic color. It did fade very fast, though part of that was my fault--I dyed it right before the biggest heat wave of the summer, so I was swimming a lot. It started to fade after a week, and has almost completely faded to a light purple/brown after 2.5 weeks. -Katyg-

Review: This colour is great and has slightly reddish undertones, which makes it perfect for mixing with atomic or cupcake pink hair to blend into purples. Lasts forever and the having a bit of blue in my hair made me so happy!! -Miss Helen-

Review: My favourite blue dye. Shows up well even on hair that isn't really light and fades to purple rather than green. Lasts ages too :) -Rachel-

Review: I love special effects! I had been dying my hair bright colours for 4 years trying all the brands i could get my hands on and this is my favourite! The dye goes on well and any stains come out easily,it lasts for ages compared to other brands which sometimes just lasted a couple of weeks before the dye washed out to show the bleached hair underneath,this dye lasts me at least two months (then i need to dye my roots) it keeps its initial colour for about a month and then eventually fades to (still bright) purples and then pinks,ive never had the bleach show right through.I love this stuff! -IntergalacticJ-

Review: I've tried many different colours on my hair, but I always return to blue, as it is my favourite....however! I always have problems with how quickly it fades, and the way it especially fades to a nasty green....but this dye is very different, it does indeed fade to a lovely purple colour...which infact got more attention than the blue I had before!! XD It did fade quite quickly for me (went purple within 2 weeks)...but I also wash my hair everyday, so for those who wash it every other day...this is definitly for you!! =D -Michelle-

Review: I, being on swim team and having before had special effects that was not faded with chlorine, decided to show my school spirit by bleaching out my hair and dying the bottom blue. Well, i acquired some Electric Blue, and for a while, it was wonderful. Then, I hit the pool. To my dismay, this colour not only fades lighter, it also fades to a different colour-- purple! This would have been much less infuriating had i not just had SE Deep Purple in my hair for 4 months and had to rape my hair with bleach to get the purple out (no semi-perm colour strippers worked very well!). Anyways, its been about, oh, i'd say a good month and a half or two. the underneath of my hair is a pastel grey-purple, and i just can't seem to get it out of my hair, and im afraid to bleach it. ANYWAYS. this colour would still be fine, if the person using it didn't ever go into chlorine. ever. even sitting in hot tubs fades this puppy. -Taylor-
NOTE FROM BEEUNIQUE - Chlorine can seriously fade these vegetable dyes (as well as bleed the colour into the pool if only recently dyed). Best wearing a swimming cap to be on the safe side. Also many blue based dyes can fade to a purple base colour although this is normally much lighter than SFX Deep Purple - you can apply more of the same colour or another purple based blue dyed to cover it and it should bring it back to a blue tone.

Review: Just the colour I was looking for, an amazing electric blue! Came out great on hair that was bleached to light blond. Lasted well for 8 weeks before it needed redying as it was starting to turn purple (though that looked good, too). A great, long-lasting blue that won't turn green as it fades. -Triada-
