About this color
Rainbow is maximalism unleashed: a full spectrum flowing through the hair, every strand a different note. It's festival energy in permanent form — and the try-on preview is the only sane way to test it before committing a single strand.

Common questions
Will the Rainbow color suit me?
Your skin undertone and base color decide the result. Upload a selfie to 3xrun and try it — you will see the real effect in seconds.
Do I need to bleach?
The try-on is free — decide after you see it. Vivid and light shades usually require bleaching; soft browns often do not.
Will it damage my hair?
The preview never touches your hair. Real dyeing with bold shades demands more care — the preview helps you decide if it is worth it.
