Whether you’re a bride planning your design, a guest wondering what to expect, or someone attending their first Mehndi event, this guide covers everything you need to know.

ToggleHenna is a natural dye made from the leaves of the henna plant, ground into a paste and applied to the skin in intricate patterns. When removed, it leaves a reddish-brown stain that fades gradually over one to three weeks.
The tradition of applying henna for weddings – known as a Mehndi ceremony – has roots across South Asia, the Middle East and North Africa, and has been practised for thousands of years. In South Asian wedding culture it carries deep significance: it is believed to bring good luck, prosperity and love to the bride and groom, and the depth of colour the henna achieves is traditionally said to reflect the strength of the bond between the couple.

The Mehndi is one of the pre-wedding celebrations – usually held a day or two before the main wedding ceremony. It’s a lively, joyful event with music, dancing and food, centred around the application of henna.
The bride typically has henna applied to both her hands and feet, with an elaborate and detailed design that can take several hours to complete. Guests – usually women and girls – also get henna applied, though typically just on the hands and in a simpler design.

“I thought tattoos and body art weren’t allowed in Islam – should I be getting henna at a Muslim wedding?”
Henna is actually actively encouraged in Islam – it’s considered a Sunnah, meaning it’s a practice recommended by Prophet Muhammad, and is traditionally used by women for beautification and to mark special occasions like weddings. So not only is it fine, it’s very much part of the tradition. The distinction is between henna, which is temporary and natural, and permanent tattoos, which are the ones considered impermissible. You can absolutely join in.
The design you go for is entirely personal. Henna artists at Mehndi events are generally very skilled and can work from a reference image – so if you’ve seen something you love on Instagram or TikTok, save it and show them on the day. They’ll use it as a guide and adapt it to suit your hands and their style.
If you bring a design they feel they can’t replicate exactly, a good henna artist will suggest something similar that achieves the same feel. Don’t be afraid to be specific about what you want – the more clearly you can communicate your preferences, the happier you’ll be with the result.
For brides: Bridal henna designs tend to be much more intricate and full-coverage than guest designs. Traditional motifs include paisleys, florals, peacocks and geometric patterns. Many brides incorporate their partner’s initials or name hidden somewhere within the design – a tradition that guests try to find at the reception.
For guests: Guest designs are simpler and quicker – usually a pattern on the back of the hand, the palm, or a single finger or wrist design. You’ll typically have a choice of a few styles on the day.

💬 Kitty asks Sim
“I’ve heard the groom’s name is hidden somewhere in the bride’s henna – is that true, and what happens if he can’t find it?”
It’s true – hiding the groom’s name or initials somewhere within the intricate patterns of the bride’s henna is a tradition many brides choose to include. Legend has it that the marriage will be a happy one if the groom can find his name before the wedding night, with the bride offering clues if he’s struggling. It’s a playful and romantic tradition that makes for a lovely moment between the couple. Whether the groom succeeds or needs a little help is usually kept between them.
For the bride: A full bridal henna – both hands and feet – can take anywhere from two to five hours depending on the complexity of the design. Some brides have a dedicated session the day before the Mehndi event so the henna has more time to develop.
For guests: Individual guest applications are much quicker – usually between 10 and 30 minutes depending on the design chosen and how busy the henna artist is. At large Mehndi events there are often multiple artists working simultaneously to manage the queue.
The depth of colour henna achieves varies from person to person depending on skin type, body temperature and aftercare. Here are the key things that affect how dark and long-lasting your henna will be:
Leave the paste on as long as possible. The longer the paste stays on the skin, the darker the stain. Ideally leave it for at least four to six hours – overnight if you can manage it.
Keep it warm. Heat helps the henna develop. Wrapping hands in a light cloth or sitting near warmth while the paste dries can improve the colour.
Use lemon and sugar. Many henna artists will apply a lemon and sugar mixture over the dried paste to help it adhere and deepen the colour. If yours doesn’t offer this, you can do it yourself before wrapping.
Avoid water immediately after removal. Don’t wash your hands for at least a few hours after removing the paste. The stain continues to oxidise and darken over the first 24 to 48 hours after application.
Moisturise regularly. Once the paste is off, keep the skin moisturised. Dry skin causes the stain to fade faster.

Henna typically lasts one to three weeks, fading gradually as the skin naturally exfoliates.
💬 Kitty asks Sim
“I’m getting henna done at the Mehndi – can I shower afterwards or will it ruin it?”
Timing is everything with henna. The paste needs several hours to dry and the longer you leave it on, the deeper the stain. You’ll notice it starts to flake and peel naturally after a few hours – this is normal. Once you’ve removed the paste, having a shower won’t affect the stain that’s already developed. The key is to be patient before washing it off – the first few hours after application are when the colour really sets, so resist the urge to wash your hands too soon.
This is worth thinking about before you arrive. Henna paste is wet when applied and takes time to dry – and if it smudges, it can stain clothing.
For the Mehndi ceremony itself, the couple typically arranges henna artists for the event – so as a guest you don’t need to do anything. But if you’re a bride looking to book your own artist, or want to get henna done separately:

Traditionally yes – henna at South Asian weddings is primarily applied to women and girls. However, this varies between families and communities, and attitudes are changing. Some men do get simple henna designs, particularly at more modern or fusion celebrations. If you’re a male guest wondering whether to join in, the safest approach is to take your cue from the family and other guests on the day.
💬 Kitty asks Sim
“I’m pregnant – is henna safe to have done?”
Natural henna is generally considered safe, but it’s always worth checking with the henna artist that the product they’re using is 100% natural before going ahead. If you have any doubt, ask for a patch test first to check for any skin reaction. The one to avoid entirely is black henna – this contains chemical additives that can cause serious skin reactions and is not safe for anyone, pregnant or not. Stick to natural henna from a reputable artist and you should be absolutely fine, but if you have any specific concerns your midwife is always the best person to ask.
Absolutely – in most cases henna at a Mehndi event is offered to all guests and there is no expectation that you’ll decline. Joining in is generally seen as a lovely gesture of participation and enthusiasm. Go for it.
💬 Kitty asks Sim
“I have work three days after the Mehndi – will the henna have faded enough not to be noticeable?”
Three days in, the henna will have faded from its darkest point but will almost certainly still be visible – particularly on the hands where it’s most concentrated. If having visible henna could cause any issues at work, it’s worth thinking about this before you get it done. You could opt for a smaller, simpler design that covers less of the hand, or consider whether the timing works for you. There’s no shame in skipping it or keeping it minimal – the Mehndi will be just as enjoyable either way.
