Henna is the cornerstone of natural hair colorization. It is the ideal alternative to conventional hair dyes, which can cause damage and dehydration in hair and also change its structure. Of course, there are also disadvantages of using henna hair dye, such as the amount of time required for the procedure and the relatively short-lasting effect.
Henna for Hair
Darkening eyebrows and eyelashes with a henna dye is very simple and inexpensive. But for some time now, more and more people have been choosing henna dyes for colorizing their hair as well. In response to the demand, manufacturers keep coming up with new interesting color palettes, which allow deepening the natural color or adding more shading. With the improved formulas, it is also possible to fully colorize gray hair.
How Does Henna Hair Dye Work?
Conventional hair dyes thoroughly penetrate hair structure and affect its coloration. This approach makes it possible to dye hair any color and have the effect last long. Sadly, the ingredients of the conventional hair dyes – ammonia, hydrogen peroxide, PPD, or monoethylamine – are highly destructive to hair. Even an intensive hair-care routine won’t neutralize the damage. Moreover, normal hair dyes irritate skin and the respiratory system.
Dying hair with henna is a whole different story. Although it can slightly dry the hair, it is generally very beneficial for its condition. First and foremost, henna and plant-based henna hair dyes don’t eliminate the natural coloration – quite on the contrary, they preserve and strengthen it. Henna penetrates the hair and changes the color by combining with keratin. This approach does not harm the hair in any way.
Advantages of Dying hair with henna
The key advantage of natural colorization is hair protection and the simultaneous, supplementary hair-care. Hair dyes based on henna contain beneficial oils, extracts, and plant-based pigments. Such ingredient list results in a healthy and natural color. Henna is also unharmful for the respiratory system and skin.
The effect of Dying hair with henna won’t be as radical, but for many people using it, that’s only an advantage. Henna gives highlights, deepens the color and gives it more texture, making the hair look generally interesting and nontrivial. Henna fades away gradually, which makes the roots look nicely blended with the colorized hair and generally less noticeable. And because Plant-based dyes have been greatly improved, it is now also possible to fully cover gray hair.
Disadvantages of Dying hair with henna
Unlike synthetic hair dyes, natural dyes with henna have a narrower spectrum of colors and shades. To get a specific shade which would perfectly match the natural color of the hair, henna dyes have to be skilfully mixed. Figuring out the right proportions takes time. With henna, it is also more difficult to get lighter shades. It is important to remember that classic henna turns the hair red, and only by using additional plant-based pigments, other darker shades can be produced.
Another disadvantage of Dying hair with henna is the amount of time required for this procedure. The powder has to be prepared at least several hours before the dying – some experts recommend leaving the diluted powder Overnight, so that the color becomes vibrant. And that’s not all: henna should stay in the hair for even a couple of hours! An hour or two are the absolute minimum.
The last thing is the Dryness that henna can cause in hair. To minimise the risk of that, henna should be thoroughly rinsed out of the hair. It can also be mixed with a hair conditioner and applied like that. In the best case, the Dryness should go away after a couple of days. However, the earthy, plant-like smell of the dye can stay a bit longer, which some people may find bothersome.
