I bought a few new towel made of 100% cotton, as seen on its label, as soon as I dried my body with it quite a large amount of hair came off and stayed on my body. Is it normal? Or should I soak it and machine wash it before first use? I didn't wash or soak it. Or is it because of poor quality? Since I've lost the invoice I have hard time asking for refund but if it's not normal I will still try to file a complaint
