IROIRO Premium Natural Semi-Permanent Hair Color 300 Neon Yellow (4oz)

This color brand are perfect better then any other semi-permanent color , they Last longer and they are God for couple times depend how much your using .

I like that the product was easy to keep yellow with out bleeding with any colour and that when seen under a black light the yellow shows up super bright then any other color

Esta marca no deja de sorprenderme. Me he echado este azul sobre un rosa de la misma marca que me duró al menos dos meses sin retocar más que raíces, y me ha dejado el pelo con jnos tonos violáceos y azules preciosísimos. No vuelvo a comprar tintes de otra marca

Dye worked well, didn't really stick to skin, and at least after my first night I did not see any dye rub off on the towel over my pilllow.However, I made this choice in color solely because it says UV Reactive on the product. I tested the day after and there was no UV reaction like I have had with similar products but from a different brand, in the past. Also, depsite bleaching I would not call the end result a "Neon" Blue. Since I bought the product for its UV Reactive purposes & neon I can only rate it 3 stars. Otherwise it is a great product and would purchase this brand in a different color if I were to bleach and dye my hair again.

It says you should keep it in your hair for at least 15 minutes, I don't think so. It colors your hair almost immediately so I'd say 5 mins, except for lighter colors. It says lime green, it's not. It's more of a grass green but overtime as the color wears away it will turn lime green. it takes about 2-3 weeks for the color to completely fade, I recommend mixing color with a little but of hair conditioner so you can spread more product through your hair while also saving as much color in the tube as possible.
