Amla and Shikakai: Hair Benefits and Plant-Based Care

If you have spent any time reading about natural hair care, you will have met amla and shikakai. They are often mentioned in the same breath, as though they were interchangeable. They are not. One is a conditioning plant that strengthens the fibre and brings back shine; the other is a mild cleanser that washes without stripping. Knowing which does what is the difference between a routine that works and one that leaves you disappointed. Here is the honest version, with no inflated claims, and a clear picture of where these plants end and plant-based colour begins.

Amla, the gooseberry that strengthens and adds shine

Amla comes from the fruit of the Indian gooseberry. As a hair ingredient it is prized for its conditioning quality: it helps coat and reinforce the hair fibre, which is why hair often feels denser and looks glossier after using it. People with fine or limp hair tend to notice the difference first, because amla can give the lengths a little more body without weighing them down.

What amla is genuinely good at is shine and resilience. By supporting the outer layer of the fibre, it helps hair reflect light more evenly, so the overall look is healthier rather than dull. It is a soothing ingredient for the scalp too, which makes it a sensible choice if yours runs sensitive. What amla does not do is change your colour in any meaningful way, and we will come back to that, because it is a common source of confusion.

Shikakai, the gentle cleanser par excellence

Shikakai, which translates roughly as "fruit for the hair", has been used for washing hair for generations. Its appeal is simple: it cleanses without the harshness of a conventional foaming detergent. Rather than stripping the scalp of everything, it lifts away dirt and excess oil while leaving the fibre's own protection more intact.

The trade-off is that shikakai produces very little lather. If you are used to a thick foam, this can feel strange at first, but lather is not the same as cleanliness; it is mostly the surfactant talking. Used as a wash or in a paste, shikakai tends to leave hair soft and easy to detangle. It pairs naturally with amla, which is partly why the two are so often found together: one cleanses, the other conditions.

Plant-based care and plant-based colour: two different gestures

Here is the point that saves the most frustration. Amla and shikakai are care ingredients. They look after the fibre and the scalp. They do not colour your hair. A true plant-based hair colour is a different gesture entirely: it deposits pigment from plants such as henna, indigo and cassia onto the hair to change or revive its tone.

Confusing the two leads to two classic mistakes. The first is expecting a conditioning plant to colour grey hair, which it will not. The second is expecting a colour to behave like a weekly treatment, when in fact it follows a method and a timing of its own. Care happens often and lightly; colour happens deliberately, with preparation. Keep them in separate mental boxes and your routine becomes far easier to plan.

The Tresse Paris approach: making plant-based simple and reliable

Plant-based colour has a reputation problem, and it is usually undeserved. People try it, the result is patchy, and they conclude that "plant-based colour doesn't work". In our experience the plants are rarely the issue. The method is. Almost everywhere, the preparation step is either skipped or explained so poorly that the pigments never have a chance to develop properly.

This is the gap our co-founder Jung Ae set out to close when she developed the Tresse Paris method. We do not claim to have invented plant-based colour; the plants have been used for centuries. What we have done is improve the experience and the reliability around it. Our colour comes as a two-step pack: one sachet prepares the fibre so it is ready to receive pigment, and a second sachet carries the colour itself. We also include a thermometer, because plant pigments reveal themselves at the right temperature, and guesswork is exactly where most home attempts go wrong.

Our colour is COSMOS Organic certified and made in France, and it won the Natexbio Challenge in 2024. It contains no ammonia, no PPD, no resorcinol and no oxidant. It coats and reinforces the fibre rather than degrading it, and it is formulated to respect a sensitive scalp. On darker shades it covers grey at close to 100%. And to be completely straight with you: it darkens, revives and covers; it does not lighten.

How to fit amla and shikakai into your routine

Think of these plants as your maintenance layer between, or alongside, colour. A few sensible ways to use them:

• As a gentle wash: use shikakai in place of, or in rotation with, your usual shampoo when you want a softer cleanse that does not strip the scalp.
• As a shine treatment: apply amla as a mask on the lengths to add body and bring back gloss, especially on fine hair that falls flat.
• Together as a weekly ritual: the classic pairing, with shikakai cleansing and amla conditioning, leaving hair soft and easy to comb through.
• Around your colour, not on top of it: keep care days and colour days separate so each one does its job cleanly. There is no need to layer everything at once.

Patch behaviour varies from one head of hair to the next, so introduce a new plant gradually and see how your hair responds over a few washes rather than judging after one. Consistency matters more than intensity.

Frequently asked questions

Does amla colour the hair?

No. Amla is a conditioning ingredient that strengthens the fibre and adds shine. It can subtly deepen the appearance of already-dark hair over time, but it does not deposit pigment the way a colour does and it will not cover grey on its own. If colour is your goal, you need an actual plant-based colour, not a care plant.

Can you use amla and shikakai together?

Yes, and they work very well as a pair. Shikakai handles the gentle cleansing while amla conditions and adds shine. Many people use them in the same wash or as a combined mask. They are complementary rather than competing, which is exactly why they appear together so often in traditional routines.

Can a plant-based colour lighten my hair?

No, and anyone who tells you otherwise is not being honest. Plant pigments deposit onto the hair; they cannot remove existing pigment. Only chemical processes can lighten hair. Plant-based colour can darken, revive warmth and cover grey on darker shades, but it works in the warm range and cannot take you lighter or give you a cool, ashy result.

Will amla and shikakai change my colour result?

They should not interfere if you keep care and colour as separate steps. Clean, well-conditioned hair actually takes colour more evenly. The main thing to avoid is heavy oiling or product build-up immediately before colouring, as a coated fibre can resist pigment. A simple wash beforehand is ideal.

Is plant-based colour suitable for a sensitive scalp?

Our colour is formulated with sensitive scalps in mind: no ammonia, no PPD, no resorcinol and no oxidant. As with any cosmetic, sensitivities differ from person to person, so a patch test before your first application is always the sensible step.
