Hey ladies, I had to do a massive brush clean. Haven’t washed brushes in a couple of weeks and I ran out of clean brushes to use. I’m still using QUO Purifying Brush Shampoo and QUO Brush Cleanser. I washed all my face brushes with the Purifying Brush Shampoo because those get washed roughly once a week except for my foundation which I usually try to do every other day. Then I used the Brush Cleanser for my eye brushes and usually I try to wash my brushes daily. But I’ve been slacking lately. I’ve had both bottles well over a year and I still have alot left. You don’t need alot at all. I picked mine up at Shopper’s Drug Mart and I really recommend these.
