There are a few reasons why nano beads can lose their colour, causing them to turn copper/gold. If you or your client’s beads turn gold, the following information can help you understand why.
The most common cause of colour loss in nano beads is due to the additives found in shampoos. Even salon quality shampoos, including dry shampoo can contain these additives; affecting beads only after a few washes.
The purpose of additives in shampoo is to create a lather, act as a thickening agent or even to keep them from freezing during shipping. If you suspect your shampoo is the cause of the colour loss, you may wish to experiment with another.
Heating tools, such as straighteners, blow dryers and curling irons can all cause nano beads to lose their colour.
Frequently touching the beads with these tools will cause the paint to soften and chip away. To prevent this from happening, avoid directly touching the beads with the tool.
Chemicals in certain medications are carried to the hair follicle through the bloodstream, causing nano beads to lose their colour.
These toxins can stay in the hair follicle for months and will not wash out. Medications, like antidepressants, birth controls, and acne medications, can induce colour change, as can Vitamin A, and narcotics.
