How to dye your hair blue with indigo

It seems like a dream, but yes, it is possible to dye hair blue without chemicals by using Indigo hair dye, an ancient plant based dye used to color jeans. To dye hair blue with indigo you will simply need to apply henna first, and then Indigo hair dye. Repeat a few times for best results.

This is obviously the best way to go if you want to dye your hair blue without chemicals. Indigo, or Indigofera tinctoria, will dye your hair dark blue and benefit, not damage, the health of your hair. The final color will depend on your base color. If you have dark hair, you will get blue black hair, if you have light hair, you will get brown black. Indigo darkens the color of the hair, so do not expect a light or green blue. A good tip is to always check that what you buy is 100% Indigofera tinctoria, with no chemical addition. Indigo is sometimes called "black henna", but on the ingredients it should always say Indigofera tinctoria. Do not confuse indigo with katam, which is also referred to as "black henna", or you will risk to end up with purple shades!

How to dye your hair blue with semi-permanent hair dye

Semi-permanent hair dye is a good option to achieve a good punk metal, even denim blue without bleaching. Just apply the blue indigo color form the Splat Midnight hair color collection, or the denim inspired hair dye line by L'Oreal as you would do with any other hair dye.

The reason why we call those hair dyes semi-permanent is because, regardless of what they state on the box, those unnatural hair colors without bleach do not last longer than 6 weeks, at least the punk, "shocking" effect.

The way Splat Midnight colors hair, for example, is by attaching micro-pigments of color to the hair. Those hair colors are meant for brunettes, or to dye your hair blue from dark brown. The result is excellent, but, as we said, it requires monthly maintenance.
