Neoquinones can make plant cells turn brown quickly, which is called enzymatic browning of food.
Can potato skin dyeing last? 1, cannot be persistent.
2, potato skin can really dye hair black, but this color is attached to the surface of the hair, and the color is washed off after cleaning.
3.

Tyrosine will gradually become another substance, and finally these substances will converge to synthesize melanin. When peeled potatoes are put in the air, they will gradually turn black. This is a fact.
This melanin is water-soluble, and it will come off after washing, so it can't stay in the hair for a long time.

Time is short, it will be washed away by water.
Potatoes contain tyrosinase and tyrosine, which will produce browning reaction when they meet oxygen under the catalysis of enzymes. At the same time, tyrosine will slowly become another substance, and these substances will become melanin when they are polymerized together. This is the so-called principle of dyeing hair with potato skin.
But in this sense, using potato skin water can change the color of hair, but saying' dyeing hair' is somewhat exaggerated. The melanin produced in this way has a characteristic that it is water-soluble, that is to say, it will fall off after washing and cannot stay in the hair for a long time. It is not feasible to dye your hair with water boiled from potato skins.
