Dye or henna?
While looking for the best for our hair, sometimes we wonder what exactly to give it, especially with this variety of cosmetic products. What should we consider when choosing a hair dye and can we expect the same results from the dye and the henna - let's find the answers to these questions comparing the two products.
The henna is powdered leaves of the plant Lawsonia inermis. Because of its natural composition, this coloring product has an extremely delicate action. Henna does not penetrate inside the hair and colors only its surface. It does not change its structure, which makes it suitable for people with finer and more vulnerable hair.
Natural henna is a good solution for women with sensitive scalp and intolerance to some cosmetic ingredients. Besides its coloring effect, henna has a strong nourishing and anti-dandruff action. Natural henna adds an individual touch to any hair, but it varies only in the red range - from orange to deep red. Often, henna is mixed with other plants such as Indigo or Cassia senna to achieve different colors, even a black one. Although its effect is limited to the outer layer of the hair, the color from henna is just as durable as with dyeing. It is even sometimes an obstruction to coloring with chemical dyes, because of the protective film that creates on the hair.
Along with all the benefits of henna, it has some minor flaws compared to artificial hair colorants. Besides offering only a limited range of colors, it is not able to lighten hair. The procedure takes more time, which, depending on the natural hair color and its density, can take up to several hours.
There are numerous hair colorants on the market, which differ both in composition and texture, as well as durability, as the latter two are caused precisely by the content of the product.
Semi-permanent dyes do not contain ammonia and are friendlier to the hair than the permanent ones. They offer a richer palette of shades, compared with henna, but are unable to make your hair lighter and to keep the color for long. There are suitable for women who are looking for regular changes rather than a lasting effect and therefore often experiment with their hair. They are normally sold in a ready to use form, which makes the dyeing procedure easier.
Among the active ingredients of the permanent hair dyes often present are ammonium hydroxide and hydrogen peroxide. Ammonia contributes to dissolution of the hair sheath and facilitates the penetration of hydrogen peroxide inside the hair. There, by the interaction of the chemical agents with oxygen, destruction of melanin and discoloration of hair takes place, after which the natural pigments are replaced with chemical colors.
With permanent dyes color saturation remains for several months, depending on the frequency of hair washing. They are an excellent solution for women who have already discovered their color or simply do not have enough time for frequent maintenance. Permanent dyes provide the best coverage of gray hairs than any other coloring product. At the moment, they are the only means by which brunettes can become blondes in minutes. The disadvantage of this type of products is that they are not appropriate for damaged hair, because of the stronger effect they have.
Most of the long lasting dyes, however, are enriched with plant extracts and oils that look after the hair’s strength and protect it from depletion. Nowadays, permanent dyes designed specifically for men are also made. Besides being consisted with the peculiarities of male hair and beard, they are in the form of an easy to apply foam and have the fastest interaction with hair - a record-breaking 7 minutes.
