How To Keep Your Colour Vibrant and Lasting: The Essential Guide to Caring for Henna-Coloured Hair

More than just a natural hair dye — it’s a ritual, a plant-based gift from nature that offers rich, lasting colour and nourishing benefits without harsh chemicals. But once you've taken the leap into the world of chemical-free hair colour, how do you keep that glow alive?

In this guide for caring for henna-coloured hair we walk you through how to care for dyed hair with all-natural and henna dye — from the crucial settling period to long-term maintenance. Whether you're new to all-natural hair colour or already devoted, these steps will help your colour last longer while keeping your hair healthy, glossy, and full of life.

1. Honour the Settling Period

After rinsing out henna, the real magic begins — but it takes time. Henna oxidises over 48–72 hours, deepening into its final shade.

During this period:

• Avoid shampooing: Washing your hair too soon can strip out pigment before it settles.

• Do not put your hair in the sea and definitely not in a swimming pool!

• Skip oils immediately after dyeing — they can interfere with the oxidation process.

• Expect your hair to appear brighter at first and then settle and deepen into its final tone after 2-3 days— this is completely normal.

2. Use Natural, Sulphate-Free Shampoo

To preserve your henna colour, ditch any shampoos with sulphates, parabens, or silicones. These ingredients can fade your colour quickly and dry out your hair.

Instead, opt for sulphate-free shampoo and products labelled for colour-treated and natural hair care.

3. Deep Condition Weekly with Botanical Blends

Henna strengthens the hair shaft but can also leave it feeling dry over time if not balanced with moisture.

Nourish with:

• Use herbal hair tonics to add moisture, strength & shine. Check out our best-selling herbal blends here.

• Deep conditioning natural hair masks.

• Regular scalp and hair oiling before every wash—try light oils like argan, jojoba, or sweet almond oil.

These natural treatments lock in shine and help protect the colour from UV and environmental damage.

4. Protect Your Colour from the Sun & Heat

Henna is long-lasting, but like all hair colours, it can fade from UV exposure or frequent heat styling.

Here’s how to protect it:

• Wear a hat or scarf in direct sunlight.

• Air-dry hair and avoid heat-styling tools where possible.

• Use a heat protectant if you blow-dry or straighten.

• Avoid chlorinated water — it can dull the colour very quickly.

• Wrap your hair in a protective head wrap or towel when using the sauna or steam room.

Bonus tip: Rinse with cool water after washing to help seal the hair cuticle and maintain shine.

5. Keep Up with Colour Boosts

Henna doesn’t fade in the same way synthetic dyes do, but it can soften over time.

To refresh your colour:

• Looking for a quick and subtle refresh? Apply a gloss treatment. Mix a thickly prepared henna paste with a good-quality silicone-free conditioner. Apply all over, and leave for two hours before rinsing.

• Reapply a full henna treatment every 6–8 weeks, depending on your hair growth, grey coverage, and desired intensity.

A Ritual of Self-Care

Taking care of henna-coloured hair is more than maintenance — it’s a gentle ritual that connects you to nature. It invites you to slow down, tune in, and nourish both your hair and your well-being. Whether you’re a natural beauty lover, a chemical-conscious consumer, or simply seeking a more sustainable hair care routine, these steps will help you fall in love with henna again and again.
