I will be getting hair tested sometime during August. The test goes back 90 days, and I will be 70 days clean. I have just found out that, Propylene Glycol, the main ingredient in detox shampoos, is also present in my everyday shampoo, TRESemme. I have been washing my hair twice a day everyday for the past couple years. I am about to start taking a product that will make my hair grow faster. What do yall think as far as the propylene glycol and me passing this test?
