I am looking for a permanet red hair dye the brighter the better. Everything i have tried is fading to a dull color. What is the best permanent one that actually works?
Sorry, but if you are looking for a true neon red then no matter what the box says they are not totally permanent. From previous experience even the 'permanent' dyes fade over time.
There are several shades of neon red in semi-permanent hair dyes, but again like permanent dyes these will fade over time. You can see all the semi permanent red hair dyes we sell here - Red Hair Dyes
