My Sigma brushes arrived last week. So far I’ve washed them with diluted shampoo. The more fluffy face brushes had minimal shedding. No shedding was observed with the majority of the shadow brushes. Might I add, they are really soft and very sturdy. Prior to Sigma brushes, I used the EcoTools Eye Brush Set. I must say, of the eyeshadow brushes, Sigma brushes are able to collect a decent amount of shadow on the brush without having to dig into the shadow. Wish I could say the same for EcoTools.
So far, so good. Maybe I’ll update you guys later on how things are going with the brushes.
