This is just pulled out of the science section, link below, and its SOLID

As long as you're using body art quality henna...... this doesn't seem
to be a problem! Seems to be the metals, not the henna! (of courese
unless you get body art quality henna, you don't KNOW if there are
metals in your henna becuase they're generally not listed!)

Compound Henna Dye

This is a term that refers to hair dye made with henna and other plant
dyes mixed with metallic salts.

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.
Ed. Just what you always wanted. Hair full of lead and sulphur. And
you thought you were using a wonderful, safe, henna product! May as
well blow dry with concentrated car exhaust.

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 toxic wonders.

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.

Natural henna does NOT have metals, lead, nor does it “coat the hair”.
Henna leaves the hair thick, strong and silky! Only pre made boxes
of “henna colors” have these toxic metals that damage your hair.

How can you find out if the henna hair dye you've been using is full
of toxic metallic salts?

Harvest some of your hair.

Mix one ounce (30 ml) of 20-volume peroxide and 20 drops of 28% ammonia.
Put your harvested hair in the peroxide-ammonia mix (this is in
synthetic hair dye).

If there's lead in the henna you've used, your hair will change color
immediately.

If there's silver nitrate in the henna you've been using, there will
be no change in hair color, because silver is coating the hair.
However, silver nitrate leaves a greenish cast to your hair, so you
can tell by that.

If there's copper in the henna you've used, your hair will start to
boil, the hair will be hot and smell horrible, and the hair will
disintegrate.
