Breakage
Why fine hair breaks when you brush it
You dread brushing. Each time, more hair is left in the brush, and your ends snap off.
Pick one off your brush. A white bulb at the root means it fell out, which is normal. No bulb means it broke.
Breakage comes from force. A thinner strand snaps under less of it. Yet most brushes are stiff, sold “for all hair types,” and many mix in nylon pins. On fine hair, that's too much.
Fine hair needs a softer brush, and a lighter hand. Start at the ends.
