Hair follicle is a living structure that keeps producing hair all its lifespan. What we need to know is that, the strand of hair residing in the follicle will naturally detach and fall after a certain period of time.

After a while new hair will form inside the empty follicle. This growth and fall make up a cycle in the hair follicle. Every follicle repeats this cycle 10 to 20 times. When the resting phase of the cycle lengthens, the hair density in that area gradually decrease. If the necessary diet and care with adequate products are not provided in this stage, these follicles will eventually die and they cannot be expected to grow new hairs again.

With this information, we can say that through proper stimulation of the hair roots at the early stage, the lost hair can be regained.
