Its Sunday and Im dying my hair....Once every 20 days I dye my hair and usually on the weekends. So Im dying my hair and get suddenly these mild cramps that make me go to the toilet. Well I suffer a lot of constipation and hard plops, so i know what is expecting me. Pain,, pain, sweating, tears and all this! O well, its not different of what i thought, its actually exactly what i knw it would be. Faces of pain, sweating, tears and all that. Big long farts and pee.
