Can You Use Shikakai Powder on Coloured or Henna-Dyed Hair?
You have just coloured your hair, or applied henna for a festival. Now it is wash day, and you reach for your shikakai powder. Then you stop. Will it wash out your new colour? Will it react with the henna? Many people love herbal hair wash but are unsure whether it is safe to use shikakai on coloured hair. The good news is that shikakai is one of the gentler ways to wash coloured hair. You just need to know when to start and how to use it. This guide explains it all in simple steps.
Can You Use Shikakai Powder on Coloured Hair?
Yes, for most people. Shikakai is a natural cleanser with a naturally low pH, which means it is mild and slightly acidic, close to your scalp's own balance. It cleans dirt and oil without stripping your hair as harshly as some strong foaming cleansers. This gentle cleansing helps your colour stay longer.
The one rule to remember: do not wash too soon. After chemical hair colour, wait 48 to 72 hours before your first wash with any cleanser, including shikakai. This gives the colour time to settle inside the hair. If your hair colour pack gives different advice, follow the pack.
What Is the Difference Between Chemical Colour and Henna?
Knowing how each one works helps you wash each one the right way.
- Chemical hair colour opens the outer layer of the hair, called the cuticle, and puts colour inside the strand. Each wash can slowly let a little colour out.
- Henna is a plant dye. It mostly stains and coats the outer part of the hair. It usually lasts well, but its shade can keep deepening for a day or two after you rinse it.
| Hair type | Wait before first shikakai wash | After that |
|---|---|---|
| Chemical hair colour | 48 to 72 hours | 2 to 3 times a week |
| Henna-dyed hair | 24 to 48 hours | 2 to 3 times a week |
| Colour plus henna (both) | 48 to 72 hours | 2 times a week, with oiling before |
Can You Use Shikakai on Henna-Dyed Hair?
Yes. In many Indian homes, henna and shikakai have been used together for generations. Wait 24 to 48 hours after applying henna before washing with shikakai. This lets the henna shade settle and deepen.
Henna can sometimes leave hair feeling a little dry or stiff. If you notice this, oil your hair for about an hour before washing. A light oil like the Karthika Curry Leaf Hair Oil helps keep strands soft through the wash.
How Should You Wash Coloured Hair With Shikakai?
- Wait the right number of days after colouring or henna (see the table above).
- Oil your hair 30 to 60 minutes before washing. This protects the lengths.
- Mix the powder with lukewarm water to make a smooth paste. Do not use hot water.
- Apply mainly to your scalp, and massage gently with your fingertips. Let the paste run down the lengths as you rinse. Do not scrub the ends.
- Rinse well with cool or lukewarm water until no powder is left.
- Pat dry with a soft towel. Rubbing lifts the cuticle and lets colour escape.

Will Shikakai Make Your Hair Colour Fade Faster?
Here's where most people get it wrong: they blame the cleanser alone for fading. In reality, every wash removes a tiny amount of colour, whatever you use. What makes colour fade faster is how you wash: very hot water, washing every day, rubbing hard, and too much sun. Shikakai's gentle cleansing is actually kinder to coloured hair than harsh cleansers.
To slow down fading:
- Wash 2 to 3 times a week instead of every day.
- Use cool or lukewarm water, never hot.
- Cover your hair in strong sun.
- Oil before washing to protect the lengths.
Hard water can also make colour fade faster. Learn more in does hard water make hair colour fade faster.
What Should You Avoid?
- Do not add lemon, vinegar or baking soda to your shikakai paste. These can make the mix too strong for coloured hair.
- Do not wash on the same day as colouring or henna.
- Do not leave the paste on for too long. A few minutes of gentle massage is enough.
- Do not skip the patch test before colouring. See our hair colour patch test guide.

How many days after colouring can I use shikakai?
Wait 48 to 72 hours after chemical hair colour, and 24 to 48 hours after henna, before your first shikakai wash.
Does shikakai remove henna colour?
Shikakai is gentle and is traditionally used alongside henna. Like any wash, it removes a tiny amount over time, but it does not strip henna quickly.
Can I mix shikakai with henna?
Some people add a little shikakai to their henna mix for easier rinsing. If you are colouring for grey coverage, it is simpler to apply henna first and wash with shikakai later.
Is shikakai safe for grey coverage users?
Yes. Its gentle cleansing suits hair that is coloured regularly. Pair it with a good aftercare routine. See our aftercare routine for coloured hair.
How often should I use shikakai on coloured hair?
Two to three times a week is enough for most people. Read more in how often to use herbal hair wash powder.
