Why do women grab your hand and start drawing henna on it?
The short answer
Women near Jemaa el-Fna grab your hand and apply henna paste before you've said a word — once it's on your skin, you're expected to pay 200–500 dirhams. The paste goes on fast. Pulling your hand back early is the only thing that stops it. Real henna art happens in completely different settings, usually arranged through a riad.
You're walking through Jemaa el-Fna or near a mosque entrance. A woman smiles, takes your hand, and before you've said yes, she's squeezing henna paste onto your skin. You didn't agree to this. She's already drawing.
Pull your hand back. Immediately. Before the paste touches skin.
Once the henna is on, you owe money. That's the mechanism. The paste stains in seconds — it cannot be wiped off without leaving a mark. The "artist" knows that a tourist with henna already on their hand will pay rather than walk away with a half-finished smudge. The price, unquoted before the grab, will be announced after the design is complete: 200 to 500 dirhams. If you protest, it goes up. If you try to leave, there will be shouting, other women will surround you, and the social pressure becomes intense.
This is not henna art. Henna art — real henna art — is a skilled practice with deep roots in Moroccan celebration. Brides receive elaborate designs over hours, applied by specialists who trained for years. Festival henna, wedding henna, Eid henna — these are cultural practices that matter. What happens in the square is a transaction that uses henna as the prop.
The dynamic is physical, not verbal. Hands in pockets or visibly occupied — holding a bag, a phone, a water bottle — reads as unavailable. Eye contact plus slowing down reads as interest. A hand taken uninvited is the start of a transaction, not a greeting. Standing still and saying "no" gets read as the opening of a negotiation. Movement is the clearest signal.
Most riads can arrange a proper henna session — a session with an actual artist who will show you designs, agree a price, and take an hour to do it properly. Budget 150 to 300 dirhams for hands, more for elaborate work. The difference between the square grab and a booked session is the difference between a transaction and an art form.
