Henna and its uses in the past and today

"The best thing with which to color your gray hair is henna or katm."
[Abu Daawood and At-Tirmithi]
Jaabir Ibn 'Abdullaah narrated that Abu Quhaafa (the Father of Abu
Bakr) came on theday of the conquest of Makkah with his hair andbeard
extremely white. The Prophet said: "Change his hair color with
something and do not use black."
Salmah, the Prophet's ,maid, said: " Anyone whocomplained to the
Prophet from pain in his head, he would say tohim, 'cup it. ' And when
complained from pain in the foot, he would tell him, 'Dye it with
henna.' " [Abu Daawood and Ibn Maajah]
She also said: "Whenever the Prophet had an ulcer, fester or eczema,
he ordered me to put henna on it." [Authentic, Jaami' al-Usool by Ibn
al-Atheer]
Henna has been utilized since ancient times as a dye to color the
nails, hands, feet and hair. The traditional henna is manufactured
from a plant known as LawsoniaAlba. This plant is cultivated in Saudi
Arabia, India, Sri Lanka, Iran, Egypt, North Africa and Australia
among others.
The effective dye component of henna is called Lawsone. It consists of
fat, resin, manitol and volatile oils.
It is mentioned in the Islamic Encyclopedia of Medicine that the
ancientEgyptians used henna in mummification.
The Egyptian henna is typically a green substance that gives the hair
a reddish brown color. Other colors are obtained by adding other dyes
to the natural henna. Some women in Sudan add a substance called
paraphenylen ediamine to the henna toreduce the time needed for dyeing
from an hour to several minutes. But this mixture can be fatal
although its cause is unknown and this is why people who apply henna
are warned against adding this substance. Henna in itself is safe
anddoesn't have any known side effects. It is 100% natural. The henna
foundin different brands of shampoos in stores and pharmacies is free
of this substance.
Recent medical researches:
Many people in recent years have been inclined to use natural
substances.The idea of returning to using some old substances that
were once used as cosmetics is gaining ground in the medical field.
One of these substances is henna. If we look at the different haircare
products available off-the-shelf like shampoos, conditioners, hair
color and hair creams, we will find that much of them contain henna.
This substance is described in the Hadeeths as being the best source
for hair dyeing. What is the scientific evidence that encourage the
return to the use of henna?
An American magazine specializing in skin diseases, Cutis, once
published an article about henna in its first edition in 1986. Dr.
Natu is a famous professor of skin disease from New York University in
America, stated that henna has several benefits, the most important
being as follows:
1. Its effects are not permanent. It does not stick permanently to the
roots of the hair like other artificial hair colors. Henna starts to
fade after 3 to 6 weeks. Itthen disappears completely and leaves no
residue.
2. Henna is compatible with all natural hair colors.
3. Henna enhances the natural color of hair and gives it shine. One
would have to use it several times before any visible changes in color
appear.
4. Henna strengthens each individual hair, restores damaged hair and
prevents split ends. There are many different shampoos and
conditioners that containhenna and do not give the hair any new color.
They give it beauty and glow.
5. Extensive usage of henna is safe in comparison with other
artificial substances. There are only rare cases of skin sensitivity.
Didn't the prophet say, "The best thing to color your hair with is
henna and katam." Recent medical evidence in our hands proves what the
Prophet said. That is not strange because the Prophet said, "Henna
isthe best perfume for the people of Jannah." If the henna is the
preferred perfume in paradise, it is the ideal hair treatment on this
earth.
