he only dye molecule in henna
(Lawsonia Inermis) in sufficient quantity to stain hair is Lawsone , which is a
red-orange molecule. Any company that
claims they create the wide range of henna colors with 100% henna, using roots, bark, or other parts of the
henna plant to achieve their colors is …… lying or seriously ignorant. Only
henna leaves are useful for dying hair, and other parts of the henna plant do
not dye hair other colors. Chemicals,
metallic salts or other plants must be added to henna to make any color other
than red.
These pre-mixed colors are compound hennas. If you buy a box labeled henna that claims
to dye hair blonde, brown or black, there is something other than henna in that
box.
Compound Henna Dye
This is a term that refers to
hair dye marketed as henna, and is
formulated in different colors.
These mixtures may contain
additional plant dyes, may contain
metallic salts, and may contain para-phenylenedmine.
Compond henna may damage your
hair.
Pure body art quality henna is
good for your hair.
There is no such plant as
"blonde henna", "brown henna" or "black henna".
The plant, henna, lawsonia inermis, has only one dye molecule, and that
molecule is red-orange.
Chemicals, metallic salts or
other dye plants must be added to henna to make any color other than red. These mixes are termed compound hennas.
Some dye plants can be added to
alter the color of henna. Some chemicals
can be added to alter the color of henna.
Metallic salts alter and fix a
dye stain. Many “henna colors” are created with metallic salts. The most frequently used material is lead
acetate, though silver nitrate, copper, nickel, cobalt, bismuth and iron salts
have also been used.
Dyes with lead acetate gradually
deposit a mixture of lead sulfide and lead oxide on the hair shaft.
When you hear that henna has
“metal”, “lead”, or “coats the hair” and “leaves it brittle”, that refers to a
compound henna dye, full of these metallic salts.
Hair bleach, permanent hair
color, and permanent wave solution are a disastrous combination with compound
(metallic salt) henna dyes. These can result in green, purple, or totally fried
hair.
Some pre-mixed hennas have
para-phenylenediamine. Some pre-mixed
hennas have very little henna whatsoever.
Body art quality henna does NOT
have metals, lead, nor does it “coat the hair”.
This website is dedicated to providing you with the information to learn
to dye your hair with 100% pure henna, indigo, cassia and amla without using
pre-mixed "compound henna".
This is very much like learning to do your own cooking instead of eating
processed food. You'll know what you're
getting and you'll know what its doing.
The pre-mixed "compound henna" products may not have an
accurate or complete ingredient declaration.
If you cannot be certain what is in each box, you cannot be certain what
cross reactions may occur between your compound henna and preceeding or
subsequent chemical process, and you won't know if you're going to have an
allergic reaction to something in that mixture.
