It is quite common for there to be a provisional increase in hair loss during the initial application period for the Hair Growth products. It is a normal response which should not last longer than a few weeks.
The reason for a slight increase is due to hair follicles reverting back to its normal stasis when inflammation subsides. When hair follicles are inflamed, the hair bulb swells leading to poor development of hair shafts and weak root anchorage. When this inflammation subsides, the hair bulb reverts to it normal stasis, weakening the already poor anchorage of hair roots lounged in the follicle. They become loosened and are prone to falling out.
Since the hair follicles are no longer inflamed, when new hair develop and become established, there is a healthier environment to grow stronger, healthier strands and maintain more durable anchorage to become less prone to shedding.
