Natural and organic approach to dyeing hair
Synthetic dyes work by raising the pH of the hair surface with ammonia in order to open the cuticle to allow the dye to penetrate the hair shaft. This in turn damages the hair.
Henna is an all natural permanent dye. Henna has a dye molecule called Lawsone in its leaves. When Henna powder is mixed with black tea or lemon juice, the dye is released, which binds with the keratin of the hair shaft, thus colouring hair.
Indigo is also completely natural and will not damage the hair, no matter how long it remains. Indigo powder is a medium to bright green powder. When mixed into a paste it is a dark rich green that slowly shows blue dye on the top and will appear a navy blue/blackish color with time.
There are a lot of companies promoting henna and indigo that is supposed to be all natural and organic. Henna products can contain metallic compounds. It is well know now that “Black henna” has PPD. PPD can also be used in either black or red henna products. PPD is not the only adulterant used. Henna or Indigo if not certified organic, could contain high levels of lead, bacteria, pesticides, solvents, skin irritating fillers, etc. So look carefully at the ingredient listing before buying.
When using natural products please keep in mind that henna and indigo will react and color your hair uniquely. The result will be different and unique on everyone depending on their hair type and condition.
Have fun experimenting!
