: how long is mixed paste "good" ?? i recently did a piece that
did not turn out - i mixed the paste on Tuesday nite (henna,
black tea, eucalyptus oil) did an allergy test on Wednesday, got
good color, then did the actual piece on Sunday. it did not turn
out - even tho the paste was on 22 hours.

: any idea what the "shelf life" of all natural paste is? the
client and i were VERY disappointed and i don't want this to
happen again.

"Do not prepare large batches of henna paste way in
advance...the mixture may separate and not be usable. More
importantly, the dying potency rapidly deteriorates. The henna
will only make visibly dark patterns for a day or two after it
is mixed. Ideally it should be mixed 5-6 hours before use."
---from The Henna (mehndi) Handbook, p. 15
Mixing the night before is fine. Experience show that 3-4 days
of dying potency is about it (we also use lemon juice in the
paste...try this), anything after that is pushing the envelope
and risking your reputation as a competant henna artist.

Pre-mixed henna paste with a "shelf-life" have some sort of
chemical preservative, such as turpentine, which is toxic. The
FDA is beginning to seize import shipments of these products.

If you are serious about doing henna professionally, you should
own a copy of the Handbook (shameless plug, but also true: we
have a pile of letters of appreciation from pros who use it).
The Henna Handbook has the most extensive practical and
technical information available on the subject in one place.
