No, "eucalyptus oil" does not work as well as "any other essentialoil". Sorry, but that's a totally inaccurate statement.
For a start, "an essential oil" by itself is going to have no effect
on henna if it doesn't have a high level of the relevant
terpine molecules for oxidation ... and those are terpineol, geraniol,
lineol, and a couple of others.
The activities of terpines (some of the molecules in essential oils)
are very specific, and oxidize henna to varying extents. Each
essential oil has different levels of MANY different terpines.
Some essential oils darken henna because they have high levels of
terpineol, etc .... and other essential oils LACKING this group of
naturally occurring hydrocarbon solvents don't darken the henna
whatsoever.
Since there are 70 varieties of eucalyptus oil, and there are varying
ways of distilling them, this question does not have a simple answer.
I've found 4 different eucs with entirely different levels of
different terpines. None of them have the high levels of terpineol
that TT does, nor do they have the other molecules in the same
quantity as cajeput or ravensara. So far I've never tried a euc that
did anywhere NEAR the darkening as TT, caj and rav. I think there
are some other eucs that have different characteristics . .... Mark
has one that smells like no other euc I've ever seen. I don't have any
of those, myself, though
Not only that, but some of the high-terp EO's have magnificent
fragrances, the loveliest being cardamom, geranium, and geranium
bourbon.
And, the ones I'm recommending have the same safety level as euc.
See the link below for details, as well as

eucalyptus oils don't do a durn thing.
