: Oh henna goddesses! Please bestow upon me your infinite wisdom and: experience so that I may learn...! *bow*
:
: I have a good question:
:
: I'm fully aware that coal tar dyes (eg. PPD) are very bad, can cause
: dermitis, are a sensitizer, etc... I also know that coal tar dyes
: are present in a lot of hair dye, cosmetics and other products. I
: assume that there's a higher rate of incidents with 'black henna'
: because of the percentage of PPD in the paste. I have no idea how
: much green dye is put in henna (especially versus PPD in 'black
: henna')... Here comes my question:
:
: Have their been records of similar PPD burns and allergic/toxic
: reactions to green dye used in henna powder? What are the risks if
: you handle and apply this henna to your skin (and hair)??
:
: I know that those little old boxes of henna powder in ethnic
: supermarkets have green dye added, otherwise it'd be obvious by the
: dusty grey colour they weren't anywhere near fresh. But I used to
: use those powders in the past, before I found this site... Had I been
: poisoning myself all along??? *eep*
Coal tar dyes are not called PPD's
