It’s like NEON yellow and I love it, kinda has a green tinge in certain lights but I think that’s cause it’s so bright
such a fun colour and
such a fun colour and easy to use
Lovely Yellow
A lot of product, enough to colour my hair and then mix it with conditioner for a few more washes. Goes on easy, did not stain bathroom. Hair is still soft (as soft as bleached hair gets). Great colour
Semi permanent dye
Great colour just not on me. First off thought product was orange but it turn yellow after a while.
VIVID
The best hair dye i have ever used ! Colour is SO bright and lasts longer on my hair than any other semi perm. Well worth the extra spend.
Long lasting, bright and perfect!
This is by far the longest lasting hair dye I have used! I have used GDY before when I wanted green hair and that was amazing too! If you’re looking for a yellow that’s similar to arctic fox cosmic sunshine I’d recommend adding the smallest amount of red to it first as this yellow is quite bright and almost neon lol. I feel like a ray of sunshine daily :)
Warmer shade of yellow
Good and pigmented, the product looks very orange when applied, but after rinsing, leaves a really rich yellow results!
Neon UV dreams
This hair colour is incredible and UV! It lasts for over a month too and smells almost like earl grey tea.

I was expected this to be like Manic Panic's sunshine and be a little bit weak but good lord I was wrong. Absolutely blasted any orange tinge away from my yellow strip!
