How to Use:

  • Step 1: Wash with the pre-shampoo to remove build-up.
  • Step 2: Rinse thoroughly and towel dry.
  • Step 3: Mix colour with activator and shake well.
  • Step 4: Apply evenly to damp hair.
  • Step 5: For natural blending of greys, leave for 20 minutes. For full coverage, leave 30–40 minutes depending on hair type.
  • Step 6: Rinse until water runs clear, then apply conditioner to lock in colour.

About the Rapid Activator:

Oiamiga’s Rapid Activator is an innovation that allows for faster processing times (depending on hair type and the result you’re after) and improved colour intensity and longevity.

Here are a few examples of timings to try:

  • For bushy bits, bikini area, beards and moustaches where you may prefer a more natural, blended look: as little as 10 minutes can be enough.
  • For finer hair: usually ready in around 15 minutes instead of the full 30.
  • For thick or coarse hair: aim for the full 30 minutes for even results, with better colour intensity and less fade thanks to the Rapid Activator.
  • For super stubborn greys: process for a full 40 minutes to achieve maximum coverage.

Oiamiga Permanent Hair Dye Jet Black 120ml is designed to give rich, glossy colour with reliable grey coverage, while maintaining hair softness and shine. With its ethical, eco-conscious formulation and versatile application, it is the perfect alternative for those who previously used Minikini or Betty Beauty, ensuring you can continue to colour with confidence.

Yes, it will, just make sure you pre-cleanse with the shampoo provided, saturate your hair with colour, and process for 30 minutes, or 40 minutes if your grey hairs are super stubborn.
Yes, it is perfect for beards, moustaches, and even your bits down below and bikini area. Please don’t use it on your eyebrows as it is too close to the eyes.
With the longevity benefits from it's Rapid Activator, we'd expect it to last up to 12 weeks, depending of course on a variety of factors such as your hair health, frequency of washing and your preferred shampoo.
Permanent hair colour requires a permanent oxidative pigment to work - be it PPD, PTD, PTDS or PTS - and all of these have the potential to cause an allergic reaction. Oiamiga uses PPD at the lowest possible level to get a great result, which reduces the risk of a reaction.
The mix is quite generous, so unless you have long hair, below your shoulder blades, or very thick hair, one box should be ample.
On natural hair, Oiamiga can lift one or maybe two shades. However, if you're colouring over pre-coloured hair, you need to choose a shade that is the same depth of colour or darker.
Betty Beauty was acquired by a US company and is no longer distributed in the UK, while MiniKini’s manufacturer can no longer produce the formula at this time.
It can be considered a replacement in terms of performance. Like MiniKini and Betty Beauty, it is an oxidative hair dye designed for delicate areas, with added botanical extracts for gentleness. The updated formula has removed older ingredients that are no longer permitted, replacing them with compliant alternatives. While no product is identical, this version is the closest available match in colour coverage and application, and it is safe from a regulatory perspective.
