As a Colorist I am neither pro nor con when it comes to using henna to color your hair. I have used henna to color
clients before and have worked with people who have used henna to color their hair at home. I must recommend
that if you use henna to color your hair that you do not try to perm or chemically straighten your hair, if you plan on
coloring your hair with any other color then henna be aware that the color will not always grab evenly to hair that
has henna residue on it. Henna is another option in coloring your hair. Like all hair color their are pros and cons to
using henna. You must weigh your options and find what is right for you
The truth about a popular form of permanent hair color. Yes, henna is permanent hair color instead of being a
metallic hair dye, oxidative hair color or a compound dye it is a vegetable tint. Even with being considered
permanent hair color henna, like most vegetable hair colors, will fade with shampooing. Vegetable tints were the first
form of permanent hair coloring. Vegetables, flowers, herbs and different types of mud were used in creating
variations of dyes for hair before technology brought us hair coloring as we know it today. Henna, logwood, indigo,
and chamomile were the four most noteworthy hair dyes and are four that are still used commonly today.
Henna's originates from plants grown in moist climates throughout Africa, Arabia, Iran, and the East Indies. Henna is
prepared from leaves that are removed before the flowering cycle, dried and ground into a fine powder. Hot water or
hot coffe/tea is added to become a paste. A lemon and sugar mixture is made to set the henna.
Many people use henna as hair color and skin dye. Henna is used in many important ceremonies throughout the
east as well as everyday skin decoration. This appeals to persons in the west and the east who prefer organic
products, it's "natural" qualities appeal to many. Henna can be found in many of the local health food stores and
organic grocers. It is found usually in four shades; black, auburn, a lightener, and chestnut. Some shades are
variations or mixtures of these four shades( ie, dark chestnut, or light chestnut). Henna colors tend to fall into the
red category and creates a brightness in it's shades.
How Henna Works: Henna owes its dying abilities to the presence of a chemical known a s lawsone. Citric or other
acids are added to create a p.H. of 5.5. Henna coats and penetrates into the hair shaft. Because of it's coating
action henna can process unevenly in hair that has uneven porosity. Henna dye coats the hair shaft and repetitive
application of henna will result in hair that is thicker and has more body. Henna can be used on hair that is fine, thin,
limp and weak with out structural damage to the hair. Henna coats the hair strand and fills in any "hole" or rough
patches in the hair, and can bond split ends to create the illusion of slick, shinny ends.
Warning: excessive use of henna dye on the hair can build up on the outside of the hair strand and create
brassiness, leaving conditioner unable to penetrate through the henna and will leave the hair dry and coarse. It may
not have the look of dry and coarse hair, however, hair will have the texture and feel of dry, coarse and damaged
hair.
The risk in using henna as a hair dye
Henna has a coating effect that if overused, can create a build up in the hair and penetrates into the hair shaft and
attaches to the bonds of the hair. This may leave the hair unfit for other professional treatments, such as:
decolorazation, perming, chemical relating, highlights, or other colorization applications. Constant build up of henna
from over coating the hair can also cause the hair to become brittle and break. There is a possibility to remove the
build up of henna or to prepare the hair for other types of chemical service. More than one application of the henna
removal treatment may be necessary to remove all traces of henna coating on the hair shaft.
