Frequently Asked Questions

What does shade 4.0 Natural Brown look like?

4.0 Natural Brown is a warm, balanced medium brown — a classic natural brown without strong red, ash, or golden undertones. It is a universally flattering shade that works well on natural dark blonde to medium brown hair.

How is Biokap Rapid different from standard Nutricolor?

Biokap Nutricolor Delicato Rapid processes in just 10 minutes instead of the standard 30 minutes of conventional Nutricolor. The Rapid formula uses a faster-acting oxidant system while maintaining the organic, nourishing ingredient profile. Ideal for those who want quick colour results without compromising on formula quality.

Does Biokap Rapid provide full grey coverage?

Yes. Biokap Nutricolor Rapid is a permanent hair dye providing full grey coverage at the correct processing time. Ensure even application and don't rinse before the full 10 minutes for best grey coverage results.

Is Biokap Rapid suitable for sensitive scalps?

Yes. The ammonia-free, resorcinol-free formula is gentler than conventional hair dyes. However, as with any hair dye, always perform a 48-hour skin patch test before full application, especially if you have a history of hair dye reactions.

Can I use Biokap on previously coloured hair?

Yes. Biokap Nutricolor can be applied to previously coloured hair. Apply to roots first, then work through the lengths during the final 5 minutes. Be aware that previously lightened or bleached hair may result in a different final shade — always perform a strand test first.
