It is not the salt water pool or the salt water that is turning your hair green. It is a poorly maintained pool with a chemical imbalance - pH and total alkalinity out of required parameters.
The color of the pool is no problem at all. If the water is green, who in his right mind would jump in?
the answer to your question is yes. i know from expierience lol i dyed my hair blonde and went swimming about 2 weeks later and now i have green hair lol. it doesnt look very nice but i would advise against it because it is really noticable. it wont go dark green it will go light green. hope this helped! Try using Ion Swimmer's Conditioner and work it through hair prior to swimming. This helps protect against sun damage, prevents green brittle hair, and helps correct damage from Chlorine.
There are many colors that go good on a blonde hair green eyed person. I would think that light colors would go best.
Acidic
well i would be swimming if a small lake
There would be no measurable difference.
Unless you have an ozonator, which would inject ozone (O3) to sanitize, there are no gases added to the water of a swimming pool.
yah i would die 4 someone like that
no because if they get wet the water will freeze, swimming would be very dangerous and suicidal.
yes they do or they would dye without swimming in salt water
If you are swimming in clean, chlorinated water this would be safe. If the water is not very clean, then there is a risk of exposing your sore to an infection. Personally, I would wait for the sore to heal.
Algae will develop in untreated water turning the water green and or foggy. If it is a swimming pool, and you don't mind, it can be treated with chemicals that you can get at the big box hardware stores or a pool supply place. If the pool is for fish you can use a biological filter and pump system.
