How to apply Lush henna

Having assessed your hair and done your strand test, you’re ready to get cracking. Here’s exactly what you’ll need:

• Your chosen henna brick (more than one if your hair is very long and thick).

• A friend to help out, if possible.

• A pair of rubber gloves or trusty marigolds.

• A bain-marie (or heat-proof bowl in a saucepan), and a stirring spoon.

• An easy-to-clean henna station (we recommend your bathroom or kitchen with newspaper on the floor).

• Clips to section your hair.

• Dark coloured towels and clothing for you and your friend.

• Shampoo and conditioner, plus a protective balm, like Ultrabland.

• Wide brush to apply henna (optional).

• Cling film or a shower cap if you’d like a more vibrant result.

Henna is best applied with a bit of help from a friend, especially if you are changing colour more dramatically but you can do it yourself - just allow extra time.

Step 1. Make sure your hair is clean and free of styling product. Wear dark clothing that you don’t mind getting a bit messy and apply your Ultrabland to the hairline and ears to prevent staining. Clip your hair up, leaving a section down at the back.

Step 2: Prepare your henna. Each brick is designed to be enough for one head of mid-length to long hair so short crops will need less, and very long hair will need more. Break the sections up carefully with a sharp knife, and place in your heat-proof container.

Step 3: Add some hot water to your saucepan and place your heat-proof bowl over the top, adding a little hot water gradually. Each cube roughly requires about 100ml of water, which should be added slowly during the process until you have a paste that resembles melted chocolate.

Step 4: Apply your henna in sections from the back of the head to the front, and from the roots downwards, using a brush or your hands. Henna takes longer to adhere to newer hair at the roots than more weathered or porous ends, so this technique enables a more even application and better coverage. Even if you’ve used a brush, you might want to finish with (gloved) hands to really coat the hair.

Step 5: If you are using Rouge or Marron and want a redder, more vibrant result, wrap your hair in cling film or a natty shower cap. This warms the hair and encourages the red colour in the henna to develop more fully. If you’ve used Brun or Noir and want a darker colour, keep the hair exposed to encourage the indigo to oxidise more fully. Taking a steamy bath is a great way to encourage your colour to develop. New henna applications should stay on the head for about two hours, but top-ups can take less time.

Step 6: Give your hair a really good rinse and shampoo to remove the henna (you may need to repeat this process), if possible, over the bath using a detachable showerhead. Rinse until the water runs clear. 

You can apply another coat of henna as soon as your hair is dry if this is part of a two-step application, or wait a while. Both henna and indigo will continue to develop over a few days and so your end result may be subtly different from your first rinse away.
