So this brush will take you anywhere from two to three weeks to break in. What I did is when I came home I just did a later up with it on my hand about three times then clean and let sit until the next day. About 2.5 weeks in and you can see the split ends. It performs exceptionally well and maintains that strong backbone so many look for. I'm glad that I bought this brush. Don't buy as your only brush due to the break on period.
