When blonde hair turns green, it’s because of oxidised mineral build up in the hair shaft. Minerals such as copper and magnesium are present in the water (either from copper pipes or chemicals added to the pool to kill algae).
The best foods for your hair are: Eggs, berries, spinach, fish, sweet potatoes, avocados, nuts & seeds.
Color not only holds better to dirty hair—clean hair can be too slippery—but if you wash your hair before coloring, the dye or bleach may burn your scalp because it won’t have the natural oils to protect it.
Semi and Demi permanent hair dyes are meant to fade out of your hair. That being said-when dying from a natural blonde to a semi or demi permanent hair color- there’s a better chance of significant fading as opposed to actually reverting back to the natural shade. However- your roots will grow back in just fine.
