To be on the safe side I'll ask an Aalim e Deen about it. For the moment, as a precaution and as much as possible let the water collect in a wash tub when you wash your hairs and afterwards pour the water in a clean place where it can be absorbed in the soil.

A little tip: Before washing your hairs wipe them thoroughly with a cloth or towel to remove the excess oil. This will require less soaping/shampooing and water when washing your hairs. You can wash the cloth or towel in a wash tub and dispose of the water in a clean place.
