Why we created this mask

If you colour your hair with pure henna and indigo, you may have noticed something: your henna tone holds up well over time, but the indigo component — responsible for deeper browns and blacks — tends to fade faster, sometimes leading to colour bleeding or patchy regrowth within a few weeks.

This isn't a flaw in your technique. It's simply how indigo behaves on natural hair colour. Indigo has a larger molecular structure than henna, and instead of bonding directly to the hair shaft, it needs to latch onto the henna molecules already deposited there. When henna is loosely bound to hair, indigo has a weaker surface to grip onto — so it fades faster and greys can show through sooner than expected.

The real reason natural hair colour fades faster than expected

This is the most common question we hear from henna and indigo users: "why does my colour not last as long as I expect?" The answer almost always comes back to this same henna-indigo binding step — not the quality of the herbs themselves, but whether they've been given the right support to bond properly on the first wash.

We created the Krya Colour Lock Hair Mask specifically to address this. It is formulated as a first-wash treatment — used immediately after any Krya henna or indigo hair colour — to help henna bind more firmly to the hair strand, giving indigo a stronger foundation to hold onto in turn.

How it works

The mask is built around Ayurvedic herbs traditionally used in ayurvedic hair colour and hair care routines to support strength and pigment retention — including Triphala, Shikakai, Khadira and Amla — combined with conditioning oils like Karanja and Babchi. Each herb is:

  • Sourced as organically grown grain, lentil or forest-collected raw material

  • Processed individually to preserve its specific nutrient profile

  • Ground and processed until it naturally forms a creamy paste — with no added synthetic base — designed to sit on the hair shaft during the crucial first wash after colouring

This process takes about a week from raw herb to finished batch, because we clean, cure and process each ingredient separately rather than using pre-mixed powders. This is what distinguishes a chemical free mask that simply sits on hair from one that actively supports the colour-binding process taking place underneath.

When and how to use it

The first wash after henna and indigo is the most important one

Apply the Krya Colour Lock Hair Mask on your first wash after colouring with any Krya single-step or two-step (Dwii) henna-indigo hair colour. Use it before your regular Krya hair wash powder or cleanser, allow it to sit briefly on damp hair, then rinse thoroughly. This first-wash window is when henna is still setting into the hair shaft — using the mask at this stage is what helps your natural hair colour last longer rather than fading within the first few washes.

What makes this formulation different

The Krya Colour Lock Hair Mask contains no synthetic builders, fillers, silicones, preservatives or fragrances — making it a genuinely chemical free hair colour companion, not just a marketing claim. Every ingredient is declared on this page, and every ingredient originates from a plant, processed minimally to retain its natural properties. Like all Krya products, it is completely vegan and cruelty-free.

Hair and scalp health are also closely tied to diet — a steady intake of good-quality protein, vitamins and minerals supports the same colour and hair strength this mask is designed to protect. Visit the Krya blog for more on nutrition for hair health.

How to Use

How to Use the Krya Colour Lock Hair Mask

Purpose of this mask

The Krya Colour Lock Hair Mask is a colour-strengthening treatment — the first rinse-off product recommended after any naturally coloured hair application. It is formulated to strengthen the bond between henna, indigo and other natural hair colour herbs and your hair strand, helping your colour last longer between applications.

Use it 1-2 days after colouring. For Dwii two-step colour, use it 1-2 days after Step 2.

Steps to apply

  1. Make a thick, non-drippy paste of the hair mask.

  2. Using a henna brush, evenly coat the coloured hair strands.

  3. Cover your hair with cling film or a shower cap to seal in warmth and moisture.

  4. Keep the mask on for at least 45 minutes.

  5. Once the mask begins to dry, it's time to rinse.

  6. Rinse out the mask thoroughly with plain water. You may notice some unlatched hair colour rinsing out — this is normal and not a cause for concern.

Post-mask oiling and wash

  1. We recommend applying hair oil to your strands and scalp for 2-3 days after the mask, to ease any post-colouring stiffness.

  2. After this 2-3 day oiling period, wash your hair with the Krya hair wash powder suited to your hair type.

Use this mask every time you colour your hair, for the best colour latching and long-term colour fastness.

FAQs

1. Why does my indigo fade so fast compared to henna?

Henna's colouring molecule, lawsone, undergoes
what chemists call a Michael addition reaction with keratin —
the structural protein that makes up your hair. This forms an actual chemical bond between lawsone and the hair strand itself.

Indigo works differently, and depends entirely on henna to work
at all. Indigo leaves release a compound called indican, which
converts to indoxyl and then oxidises into indigotin — the
deep blue-black pigment responsible for indigo's colour. But indigotin cannot bond to keratin directly. Instead, it needs the lawsone layer that henna has already deposited on the hair, using that layer as its bonding substrate.

In effect, indigo's colour is only as stable as the henna layer
beneath it. If that lawsone-keratin bond is weak or incomplete, indigotin has a less stable surface to hold onto — which is why indigo tends to fade noticeably faster than henna, even under normal, gentle hair care.

2. Is it normal for indigo to fade within a few weeks?

Yes. Since indigotin depends on the henna layer beneath it rather
than bonding to hair directly, some fading is expected within a few weeks.

Even henna's own lawsone-keratin bond, though chemically
stronger, can weaken faster than expected if the hair cuticle is compromised — through heat styling, chemical treatment or rough handling — since damaged cuticle areas offer fewer intact sites for lawsone to bond to in the first place.
And if the henna layer is weaker, indigo which relies entirely on that layer fades even faster on top of it.

3. Does indigo wash out completely, or does some of it stay in my hair permanently?

No — henna and indigo are semi-permanent
colourants. Lawsone's bond with keratin is strong but not indefinite, and indigotin's dependence on that lawsone layer makes its hold even less resistant to washing over time. Both colours will gradually fade, though indigo typically fades faster since it has no direct bond of its own to fall back on.

4. Why does indigo need henna to "stick" to hair?

Because indigotin — indigo's active pigment — does not form a
direct chemical bond with keratin the way lawsone does. It has no mechanism to attach to hair on its own. Instead, it requires the lawsone already bonded to the hair from a prior henna application, using that layer as the surface it deposits onto.

Without this henna base in place first, indigotin has
nothing to hold onto and will not colour hair effectively at all.

5. Why does washing my hair too soon after colouring make the colour fade faster?

Henna and indigo need approximately 1-2 days after application to fully oxidise — a chemical process where lawsone (and indigotin sitting on top of it) darkens and stabilises within the hair shaft. Washing before this window closes can interrupt that process, meaning the colour may never reach its full depth in the first place.

Krya recommends leaving colour to oxidise for 1-2 days before your first wash. After that, the bond is essentially locked in : but washing in ways that damage the hair cuticle (harsh scrubbing, rough towel-drying, high heat) will still accelerate fading over time, since a damaged cuticle offers fewer stable sites for lawsone to hold onto.

6. Can shampoo or conditioner strip out indigo colour?

Shampoo does not undo the oxidation that has already taken place — once lawsone and indigotin are bound within the hair, that chemical process is complete and can't be reversed by washing. However, regular shampooing, especially with sulphate-based or harsh detergent shampoos, gradually strips away surface-level pigment over time and can accelerate how quickly indigo — which is less firmly bound than henna to begin with — fades from wash to wash.

Conditioner does not strip colour. But it's worth knowing that
conditioner can mask early signs of poor colour uptake — if your hair's cuticle is too damaged for henna to bind well in the first place, conditioner will simply smooth over that problem rather than solve it.

7. Does hot water affect how well henna and indigo set into hair?

Yes. Hot water accelerates fading of both henna and indigo, and
is generally discouraged in Ayurveda for hair and scalp health more broadly — prolonged exposure to very hot water on the scalp can cause irritation and, with repeated habitual use, has been linked to broader concerns around scalp and eye area sensitivity. Krya recommends lukewarm or cool water for
all hair washing, not just immediately after colouring.

8.Should I avoid oiling my hair right after henna and indigo application?

Yes. After colouring, leave the colour to oxidise for 1-2 days, then use the Krya Colour Lock Hair Mask as your first wash.

Hold off on oiling until after this first-wash step — introducing oil before the henna-indigo bond has fully set can interfere with the binding process this mask is specifically designed to support.

Once you've completed this first wash, you can resume your regular oiling routine (as outlined in the Post-Mask Oiling and Wash steps above).

9. How does the Krya Colour Lock Hair Mask help indigo bind better?

Indigotin cannot bond to hair on its own — it needs the
lawsone-keratin layer created by henna as a base. So indigo's strength depends on how tightly lawsone has bonded to your hair.

Lawsone bonds more effectively under acidic conditions, but not
every acidic ingredient works well with hair chemistry. We've specifically chosen herbs like Triphala and Hibiscus — with a long history in Ayurvedic hair treatments — for their acidic, hair-compatible profile that supports a tighter lawsone bond.

A tighter lawsone bond gives indigotin a more stable surface to hold onto , which is how this mask supports stronger colour lock for both henna and indigo.

10. Do I use this mask instead of conditioner, or in addition to it?

Use this mask on its own, in place of conditioner, as your first
hair treatment after colouring. Introducing a separate conditioner at this stage can interfere with the colour-binding process taking place. Once this first wash is done, you can return to your regular routine, including conditioner if you use one.

11. Can I use this mask if I only use henna (no indigo)?

Yes ! this mask supports henna's bond to hair on its own too, not
just the henna-indigo combination. If you've used henna consistently for a long time, your hair may already bind it well, since regular henna use itself strengthens hair over time.

This mask is most useful if you're new to henna, or if you find your henna colour isn't lasting as long as expected.

12. Will this mask work with henna and indigo from other brands, not just Krya?

Yes. The Krya Colour Lock Hair Mask works with henna and indigo
from any brand . It supports the same lawsone-keratin bonding process that takes place with any pure henna or henna-indigo colour, regardless of brand.

13. When exactly should I use this mask — same day as colouring, or a few days later?

Use it 1-2 days after colouring, on your first wash. See the "How to Use the Krya Colour Lock Hair Mask" section above for the full timing and application guide.

14. How long should I leave the mask on before rinsing?

Apply as a thick paste and rinse once it begins to dry , the same
way you'd use any Krya hair mask. Full application details are in the "When and how to use it" section above.

15. How often should I use this mask — every wash, or only right after colouring?

Only on the first wash after each colouring session, not every
regular wash. See the "When and how to use it" section above for the complete routine.

16. Will this mask change or lighten my colour result if used incorrectly?

No. This mask contains no henna, indigo, or heavy surfactants, so
it will not lighten or alter your final colour result.

 17. Does this mask contain any chemicals that could interfere with natural henna-indigo dye?

No. The Krya Colour Lock Hair Mask contains no synthetic
chemicals, sulphates, or silicones that could interfere with your henna-indigo colour. Every ingredient is a processed Ayurvedic herb, chosen specifically to support — not disrupt — the colour-binding process.

18. Is this mask safe to use on grey or white hair roots specifically?

Yes. This mask is safe to use on grey and white hair roots, and
works the same way to support colour lock in these areas as it does elsewhere on the hair.
