For most people, shedding will start between 14 and 21 days after their first treatment, as the effect of the chemotherapy drugs on the follicles begins to show. For those who don't scalp cool, this would be when total hair loss would begin. For those scalp cooling, shedding will continue at some level through treatment and for some time afterwards. The heaviest shedding is usually around treatment 2 and 3 of chemotherapy. For the majority of people shedding will slow a little after this.
It is important to remember that shedding does not mean that scalp cooling isn't working, but is an inevitable part of the scalp cooling process.
