Henna hair dye: safety, usefulness, and limitations.

-

 Henna is a natural temporary coloring agent obtained from leaves and tender stems of the plant,  Lawsonia imtermis. Used on skin and hair, it gives a typical brownish orange hue to the part. 

Henna and hair color

Henna gives a typical color to the hair. It hides whites but does not blacken it unfortunately. Hence it is not a versatile hair dye. It also takes many hours to produce effect. The color though natural is not permanent. But how safe is it?


Henna for hair and its safety

Since henna is natural, it is a natural tendency to think that it is a safe option to the chemical dyes for hair. But is it so really?

Henna does not penetrate into hair shaft and only remains on the hair surface. Hence it sits there preventing any hair conditioner to reach the hair cuticle. Hence hair could become lifeless and brittle with repeated use. Henna per se does not condition the hair. 

Though predominantly non-allergic, henna does have a low allergic tendency. But some cases of allergy could be due to the other components mixed in the henna-based hair dye mixture including contaminants such as nickel and cobalt. 

Henna does have some action against Malassezia furfur, the fungus causing dandruff. 

Remember 'black henna' has PPD in it in high concentrations. Hence for people allergic to it or looking for PPD free hair dyes, it is best avoided.

Color therapy-the ancient art of healing! Know the science behind it and its current status!

  Color as a form of therapy is not a new concept. In it, electromagnetic waves in the form of the visible spectrum (that we interpret as colors) are used to cure various body illnesses. It is an ancient mode of therapy that is being reinvented. There are attempts to elucidate its scientific basis and explanation. This would help to explore and discover newer dimensions of this old remedy. Color therapy (Chromotherapy) Newton talked about solid matter and moving objects while Einstein found out that mass and energy are dual expressions of the same universal substance. It is the vibration rate of its molecules that determines its form. When slow, it is physical matter and when the vibrations are intense it is energy. Thus, light is an energy and when it interacts with matter, color is formed. Each color has its own wavelength, frequency, and energy level. And human eye is adapted to see only this energy that has a wavelength between 380-780 nm. This is therefore, the visible spe...
