Quicklime is nasty stuff .... it doesn't have the "reek" quality of
ammonia, but it's not any easier on your skin.
Slaked lime is less vicious.
Concerete has lime but isn't as vicious either.
Look for something that says calcium hydroxide (slaked lime)

To quote from one of those:
"Limewater is a clear, saturated water solution of calcium hydroxide.
It is used in medicine to treat acid burns "
This indicates that lime will react with the hennotannic acid in your
skin.

Also, crucial .... when calcium oxide is mixed with water it gives off
a lot of heat, so the combination of reacting with the acid and
getting right hot is going to have a major effect on the henna color.

Here's what to look for:

The white stuff that people mark out lines on grass so they can play
football or something.

The white stuff that people use to make their walls paster-ish white
that is NOT paint.

The white stuff people dip betel leaves into.

The greyish stuff builders use to paste bricks together to make a
wall.

The powder gardeners and farmers use to "sweeten" acidic soil.
