How much do Henna Tattoos usually cost?

Question

Are they dangerous at all? (chemical wise) I would like to get one on my pregnant belly at halloween time.

Answer 1

Cost varies a lot, since you can do them yourself.

Chemically, if you use real henna (red or brown) you should be fine.  I understand some people do have a mild skin reaction, although that should be pretty rare.  If it's just for Halloween, you might consider something less of a pain to do and not as long lasting.  Airbrush might be a nice option.

Avoid black henna like the plague, btw.  That is nasty toxic.
