What is neutral henna powder? Tape for taping henna?

I bought a bag of "neural henna powder" from the bulk bin at the coop in the city near my home. I mixed it up according to usual but even after like 2-3 days there did not seem to be any dye release. SO what is neural henna? Is it just for conditioning hair? Is it no good for body art henna application? I bought a BIG bag...should I just toss it out and not waste my time?

What is the best way to wrap or seal henna? Do I want to literally wrap an arm or leg in toilet tissue paper and then wrap it in saran plastic wrap and tape it sealed for overnight? Wont it cause sweating and smearing?
Which tape is best for holding the semi dry paste in place? I have just bought some J& J Waterproof tape from the First Aid aisle at the store. Also saw "paper tape' though and wondered if either one is going to hurt like crazy taking off. The I saw these J&J Tough Pads- hydrocolloid adhesive pads, labled water proof and sweat proof. they are only 2. 4" x 2.4" squares though but heard you can shower with them on....
So what is best for an arm or the low staining shoulder area? And any tips for the back "trailer trash stamp" henna tat on lower back area?

Yes "neutral henna" is meant just for conditioning. In my experience henna from a bin is not worth using on skin.

Skip the saran wrap secured tissue wrapped like a burn victim is the way to go.

I like mefix but then I am allergic to many adhesives.

What Amy said! You really have to hit www.hennapage.com. All of these questions could have been answered right away when you thought of them with a simple 'search'!

The Canadian version of mefix is hypafix. I'm not fond of papertape either.
Here are some other suggestions:

Here is a great and full explanation of neutral henna (which is actually not henna at all) When you go to most healthfood stores, remember that they are vendors/shopkeepers and rarely understand EVERYTHING they sell. Often very far from it. Best to know your stuff!

Have fun!

YEs, thanks. Actually I have read Hennapage and hnna caravan several times.
I wanted to ask the forum because I just bought medical tape by Johnson & Johnson and saw it was waterproof and wondered it that would hold in too much sweat and smear?
I just did a gals back and she did not want "sealer" - I use non areosol hair spray, and wraping her back with tissue would be difficult. I suggeted paper tape that I had...but she did not want any tape. I used my best henna from Henna Page company in OHIO and good terps. THe design covered her back with feathery plumes. She said she would leave it on an hour or two and then 'brush' off the paste before she went to bed......THe paste did seem to be drying quickly...
A week or two later she told me "it wa OK but not very dark"! She was nt really complaining but was sort of disappointed. I am sort of disappointed too because I spent about an hour laying out the design and applying the henna.
I dont think it was the henna but the short amount of time on skin.Thanks for responses.

That's a tough one! You use the best stuff, and if they client REFUSES to do what's right...where do you go from there??
You just have to say "Sorry you didn't get the results you had hoped for, but that is why aftercare is so important".
Look into the mefix/hypafix. Stretchy, flexible, cottony, less likely to hold in too much moisture under normal circumstances. May be your best fall back in cases like this one!

Henna on a back just wont get as dark as it will other places too.
