If one wishes to use powdered indigo as hair dye, there are several safety concerns which need to be taken into account in order to avoid risks that may have a negative impact upon one’s health. One of the usual risks is the various toxic chemical compounds meant to enhance color or give dyed hair unusual color intensity in sunlight. Pure indigo powder does not contain any toxic substances, however some industrial procedures are known to add dangerous chemical to hair dyes in order to make them look similar to natural ones. Para-phenylenediamine, or PPD, is one of the harmful compounds used to mix indigo powder hair dyes. A black or brownish-black powder that leaks brown liquid when the powder is mixed with water is usually the best way to tell whether the dye is natural or unhealthy.
Indigo powder originates from India and is processed from a plant called Indigofera tinctoria. In order to choose the best indigo powder, one should ensure that the product is authentic. There are numerous products that claim to have indigo coloring that may not actually contain the actual substance. The authenticity is important both for safety and to achieve the desired results.
Indigo powder is known to be one of the oldest hair dyes, as its use for dying hair black dates back to the 19th century. Indigo powder is usually a healthy, risk free hair dye, as in its natural state, it is not chemically dangerous in any way. Indigo hair dyes are permanent, meaning they do not wash out when hair is shampooed, so it is important to be sure of the decision if one chooses to dye his or her hair with it.
Additionally, it is important to note that indigo powder does not color hair blue or violet shades, as is often thought. It is most appropriate for those who wish to dye hair a rich black. Often, it is used as an alternative for individuals who are allergic to synthetic black hair dyes.
Cosmetic salons usually employ trained professionals who can apply hair dye safely. They may also be able to inform customers about the contents of the hair dye if there are any concerns. Properly operated salons will also explain the safety measures that are taken during the process.
