There are several reasons to use henna for eyebrows. The fact that it is a natural alternative to other chemical dyes and that it can be mixed at home are its main benefits. It also colors the skin as well as the hair, and can be mixed with other liquids to get lighter or darker colors. There are a few disadvantages to using henna for coloring eyebrows, including difficulty of application, rapid color loss, and failure to "take" on all hair types.
The biggest benefit of using henna for eyebrows is that it is an all-natural alternative to store-bought brow tints or dyes. It's also very easy to mix the henna power, and it can be stored in the refrigerator for up to 30 days prior to use. Henna might be a good choice if someone already uses henna on her hair and wants her brows to have the same reddish color.
One of the other benefits of henna for eyebrows is that it colors the skin as well as the hair, and this can create a longer lasting stain. Applied correctly, henna creates a stain that should last between five and seven days. The stain underneath the brow hair can also help to create the illusion of darker brows.
The biggest disadvantage of using henna for eyebrows is that it is difficult to apply. Henna paste is thicker in consistency than conventional brow tints, and it can prove difficult to get the paste to cover all of the eyebrow. It can also be messy, and since henna colors the skin, the user may end up with stains where they aren't wanted. A simple solution to this is to smear petroleum jelly in the area around the brow before application or to use a brow guide or stencil.
Another disadvantage of using henna for eyebrows is that the color tends to fade quickly, which may be due to the growth cycle of the brows or to the thinner skin in that area. A henna stain around the eye will typically last for up to a week, but frequent reapplication may be necessary to maintain the color.
One of the most common complaints is that henna doesn't color all hair or brow types. Individuals who have darker and coarser brows may find that henna simply stains the skin underneath and does nothing to the eyebrow itself. One solution may be to pre-lighten the brows and then apply the henna. Another way to help ensure that the henna works as it should is to cover it after application. Henna works best when it's kept warm and moist, so applying strips of cellophane over the eyebrows may give better results.
