Normal shedding can equal about 100-200 hairs per day. Normal shedding is due to the cycling of hair follicles on and off. Out of the ~100,000 hair follicles on your scalp, about 14% are not producing hair any given day. Each day some follicles turn on and some turn off, producing a release or shed of the hair fiber while the follicle is ‘resting.’ The less often you shampoo and brush your hair, the more shedding you will notice. Starting strong hair regrowth treatments like minoxidil or laser therapy can result in a strong, short-term shedding phase as follicles turn on and grow a new hair, the hair fibers push out the old resting hairs, which indicates the treatment is working*.
