Henna is a plant, lawsonia inermis, and has been used for thousands of years to dye the hair and skin.  The dye molecule, "lawsone" penetrates the skin and hair, bonding to the keratin.  Henna dye blocks UV so your hair is protected from damage from the sun.  Henna for hair also strengthens your hair, reducing split ends, eliminating dandruff, killing lice and nits, and making your hair shiny and glossy. You should always use body art quality (BAQ) henna powder to dye your hair.  BAQ henna powder has a high dye content and differs from body art henna powder because it is not triple sifted.  BAQ powder is easy to rinse out, and leaves the hair a rich, lush color.  Any henna powders used on the hair must be pure henna powders, with no additives, metallic salts, or synthetic dyes.  100% pure BAQ henna powder is safe to put over synthetic dyes, and can be bleached or dyed over without damaging the hair. Because the dye molecule binds to the keratin that surrounds the hair core, the stain for each and every strand is different.  This results in rich, lush and vibrant hair, when using BAQ henna powder to dye the hair.  

Cassia is a plant, grown mostly in Egypt.  It looks just like the henna powder, but does not stain the hair or hands.  It is an excellent conditioner, making hair glossy and thick, and promoting a healthier, and dandruff free scalp.  Historically, cassia has been used to cure fungal and bacterial infections.  Cassia is applied to clean, dry hair, and left on as a conditioning treatment for 30 minutes.  It is also mixed with BAQ henna powder to tone down the red and increase gloss and shine!  Cassia is mistakenly known as "neutral henna."  There is no such thing as neutral henna, and cassia does not have any staining qualities.   

Indigo is a plant grown in India and Pakistan.  The powdered leaves have a natural, dark blue dye, and can be applied to the hair to dye the hair dark. When indigo is combined with henna powder, it produces deep red-brown to jet black shades.  Indigo is great for covering grays and dying your hair naturally without any chemicals!

Amla is a plant powder from the dried and ground fruit of the Indian Gooseberry tree.  It contains natural tannins, vitamin C, and acts as a natural astringent.  For centuries, women have been using amla to promote healthy, glowing skin and hair.  Amla is an excellent way to increase volume, boost curls, as well as a natural facial scrub and toner.  It helps with the uptake of other dyes, but does not have a dye itself.  When used regularly, amla powder helps maintain strong, healthy hair.
