Answer 2

I used to know the ins and outs of this when I was in Beauty School... but I haven't used the knowledge in awhile so here...

Vegetable dyes: If pure are extracted from plants e.g. Saffron and Camomile, Privet, Black Myrtle leaves, Poppy heads, Green Walnuts, Ilex roots. Most vegetable dyes will wash out of the hair.
Henna however is a 'permanent dye' (the molecules are small enough to enter the cortex of the hairshaft) with the colour being oxidised by atmospheric oxygen. Henna may change the feel and lustre of hair.
Pure Vegetable dyes are basically harmless and do not require allergy tests. It is unlikely that any adverse skin reaction or hairshaft damage would result from their use. Egyptian (Vegetable) Henna however can, in some people, make the hairshafts seem dry and lustreless. This is not injurious. This form of henna is used in some shampoos e.g. to provide auburn highlights.
Camomile is another vegetable dye. The active ingredient is Apigenin (tri-hydroxyflavone). It is obtained from dried flowers of the Camomile plant. It coats the hairshaft adding a yellowish hue.

Answer 3

A dye made from vegetables?
History shows that vegetables were used to dye a variety of things. For example: Beets give off a red color...if you have ever handled fresh beets, your hands are red when you have finished.

Answer 4

Made from vegetables. Almost all dyes in the past (with the exception of those made from minerals) came from plant material. Blueberries, strawberries, leaves, bark, etc.

Answer 5

It calls Hna (may be different spelling for english speaking countries) but it is suitable only for dark or red hair like treatment and to add shine.

Answer 6

Majority of these are Henna based.
