If you want to use powdered indigo as a hair dye, there are a number of safety issues to be aware of to avoid risks that could have a negative impact on your health. One of the common dangers is the various toxic chemical compounds intended to enhance color or give colored hair an unusual intensity of color in sunlight. Pure indigo powder does not contain any toxic substances; however, some industrial processes are known to add dangerous chemicals to hair dyes to make them appear natural. Paraphenylenediamine, or PPD, is one of the harmful compounds used to mix indigo powder hair dyes. A black or brownish-black powder that loses a brown liquid when the powder is mixed with water is usually the best way to tell if the paint is natural or unhealthy.
Indigo powder originates from India and is processed from a plant called Indigofera tinctoria. To choose the best indigo powder, you have to make sure that the product is authentic. There are numerous products that claim to have indigo dye that may not contain the actual substance. Authenticity is important both for security and to achieve desired results.
Indigo powder is known to be one of the oldest hair dyes, as its use to dye hair black dates back to the 19th century. Indigo powder is generally a safe and healthy hair dye, as in its natural state it is not chemically dangerous in any way. Indigo hair dyes are permanent, meaning they don’t go away when you wash your hair, so it’s important to be confident in your decision if someone chooses to dye their hair with them.
Also, it is important to note that indigo powder does not dye hair blue or violet, as is often thought. It is more suitable for those who want to dye their hair deep black. It is often used as an alternative for people who are allergic to synthetic black hair dyes.
Beauty salons often employ trained professionals who can safely apply hair dye. They can also inform customers about the content of the hair dye if there is any doubt. Properly operated salons also explain the security measures that are taken during the process.
