These are fabulous brushes and I am very very fussy about hair care products. I have Arthritis in my hands and struggle with pain and grip. These are lightweight yet so easy to hold and grip whilst twirling them around my hair and roots. I love the curved shape which is good for my strong thick difficult hair, they define and separate well without tangling too. The different sizes are ideal for different lengths of the hair to create body soft curved fringes and shaping the nape of the neck. Absolutely delighted I found these gems.
