I tell all clients that each ringlet is with their friends. When texturizing shears are used, you take away half the friends. The ringlets gets pissed, then frizzes. I have curly hair and the only reason I specialize in it was because I used my poor head as a test dummy. Thinning shears are NO BUENO. Might work for a bit, but does not grow out well. I think individually taking each ringlet and cutting it with the direction of the curl in my mind works better. However I always tell people that it's all about finding the stylist whose style works for them.
