It’s actually really easy to recreate
This deceptively complex looking style is easy to do yourself with a simple dyeing technique. Just repeat the technique on sections through your hair and you’ll have this amazing, multifaceted rainbow hairstyle!
You can either dye hair extensions or colour directly on your own hair in back-to-back slices. It’s a bit time time-consuming, so I recommend dyeing just a large chunk of your hair. If you’re using extensions, make sure you stack them on top of each other for the full mesmerising rainbow effect!
You will need…
- Crazy Color Toxic UV
- Crazy Color Caution UV
- Crazy Color Rebel UV
- Crazy Color Anarchy UV
- Crazy Color Bubblegum Blue
- Crazy Color Rainbow Care Conditioner
- Light blonde hair (your own, or a weft)
- Tint brushes, mixing bowls, gloves
- Foil or meshes (optional)
Of course, you can substitute any of these for similar dyes of your choice.

Applying the Colour
- Dilute the dyes
To get this lovely light, prismatic colour effect, we’re going to dilute the UV colours with conditioner to make them more pastel. I’ve mixed each of these 1:1 with conditioner, but left Bubblegum Blue as it comes since it’s already a pastel. - Apply the colours
This part is simple. Use a tint brush to paint on the colours in rows in rainbow order. If you’re not using a clip in extension, use foils or meshes to keep each layer separate. Using thick sections will increase the risk of missed spots, so take only thin sections to allow the dye to go right through to the other side. - Now wait
Pastels need longer to soak into the hair so make sure you allow at least 30 minutes to penetrate your hair. Crazy Color is non-damaging so you can allow the dye to sit for longer as long as it doesn’t dry out. - Rinse cool
Use cold water to rinse out the colours. This will reduce bleeding. Follow with conditioner.
