A little something for the chemically literate:
After years of dyeing my hair with indigofera tinctoria I want to let it grow out. Not wanting to cut the good and healthy hair out in a couple years I thought about chemically removing it.
Although there isn't much information about my specific question I found that conventional fibers like jeans get dyed through vat dyeing, a process which uses pigments which aren't water-soluble and transforms them through a reducing agent into leuco-indigo (watersulable and colourless). This will get into the fibers (being only half the size of the indigo molecule) and after oxydating it gets blue again.
Therefore it should be possible to dip my hair into a reducing agent so that the indigo gets broken into indoxyl/ leuco-indigo which should be possible to wash out.
Repeating till enough indigo has washed out and doesn't reoxydize anymore into a dark blue.
Thought about using sodium dithionite.
Question: Does it sound chemically possible and if so, what should I consider? Will my hair get rekt instead of the indigo? Will I just kms?

Just checked out where to buy it, so I can already try different solutions on combed out hair. Besides some scents a product for colour removing on cloths is pure sodium dithionite.
I think I will just try 5, 10, 15, 20, 25 and 30% solutions with lukewarm water.
Well, it should only really react with the indigo. If cotton and silk will not disintegrate while being treated my hair should be able to deal with it, especially on the lower solutions.
I guess a skin test would also be a good idea in case anything does come into contact with my scalp.

You can't bleach indigo. It will get green. Not the nice kind of green but diarrhea green.
