You told us the new henna bricks weren’t up to scratch, so we’ve listened and we’re busy putting this right. We don’t expect this to take long, but if you’re a regular henna user, don’t despair - sign up to the customer newsletter to be kept up to date on exactly when you can get your hands on your favourite herbal hair dye.

What’s in it for you?

Try this henna and hibiscus brick for naturally beautiful shades of red. Our henna hair dye is ideal if you have a hair dye allergy, are looking for a safer alternative to synthetic hair dye or just want glossy, healthy hair. 

What colour will you get?

Rouge will give fiery copper hues to blonde hair, warm red tones to brunettes and adds a subtle, glossy warmth to very dark heads of hair. Use over greying hair for a warm, twinkly highlights effect, or as an essential base before applying Lush's Noir, Brun or Marron henna hair dye to fair, white or greying hair. 

You can make sure henna is the right choice for you by reading our FAQ.

How does it work?

Henna contains a pigment called lawsone that has an affinity to the keratin in your hair. It adheres to the cuticle, adding a layer of sheer colour without changing your natural hair colour. This will very gradually fade over time. Henna can be used to help bind other materials to the hair like the hibiscus in Rouge, which brings added depth and vibrancy to your colour. We add cocoa butter because it softens and aids slip through the hair as you apply and enables us to make a solid, self-preserving product.

How to use: 

To get the best results, please closely follow our how-to-use steps here.  Our unique cocoa butter henna brick is designed to be enough for one head of mid-length hair and melts down with hot water into a mousse-like blend which you should apply generously. We recommend doing a strand test first to make sure you are happy with your chosen shade - ask us in-store for a sample. 

What’s in it for the planet?

A majority of synthetic hair dyes contain chemicals known as aromatic amines that are not only associated with health risks, but may bioaccumulate in our ecosystem. Hair salon wastewater has been found to contain colour molecules unconsumed by the dye process, as well as mutagenic byproducts, that are not believed to be effectively removed from our water systems. Choosing a plant-based dye like Lush henna reduces the number of these materials in circulation.

How to store:

Your henna brick will arrive in a beautiful recycled paper packaging, inspired by the angular henna designs traditionally found in North African skin art. Keep your henna brick in its wrap in a cool, dry place, ready for when you use it. Henna bricks are best used fresh and you can put any leftover melted henna in your compost.

To continue our commitment to reduce single use plastic, your henna will no longer come with plastic gloves. Please protect your hands with your trusty reusable rubber gloves. 

“Henna applications remind us of the importance of self-care. This is not a beauty treatment to be rushed, but savoured.”
