What are flakes?
The white flakes that appear in your hair and fall onto your clothes are actually clumps of dead skin cells that
have been shed by your scalp. Everyone sheds dead skin cells from the scalp, but various factors can speed up
the usual rate of shedding dead skin. In a healthy scalp, new skin cells are continually formed at the lowest
level of the skin and move toward the outer surface. When they get to the surface, the skin cells die and shed.
The movement of these cells to the outer layer usually takes about 28 days. But when there’s a problem, this process
occurs between 7 and 21 days. Instead of shedding individual cells that are virtually unnoticeable, the dead skin
cells are shed in large flakes consisting of hundreds or thousands of cells clumped together with body oils.
