hmmmm stop dyeing my hair, and go back to snow white hair? NEVER, I have repeatedly and for prolonged times exposed my scalp to Selenium.

Use common sense. Wear gloves and have proper ventilation.

Concentrated goes without saying to handle cautiously. Beyond that the worst you will have to contend with is: if you are sensitive to the substance, some dizziness from prolongeddddddddddd breathing. I doubt we are going to drink the stuff. Our hands are an other matter. We need to wear gloves wo we can keep our orginal skin color. I know when the hair dye gets past the hairline onto my forehead, I wear some of the smarks of the selenium. Reminds me I need to get my hair retoned soon.
