4/5 [SEP] the reason why this isn't a 5/5 but a 4/5 is due to the fact you have to stretch it for a good minute so it doesn't cause you a headache but I love it and use to when I'm washing my face/doing a mask. This prevent traction alopecia of the hairline that is caused when washing your face and it makes sure my silk scarf/bonnet doesn't get wet as well.
