| Effluvium anagen is a temporary condition, implying that the hair will grow back within a 6 to 12 month period after the treatments. |
| The events of early anagen are, in effect, a reenactment of the early development of the hair follicle. |
| A new period of anagen starts with cell proliferation of the secondary germ, which then extends inward to reinvest the dermal papilla. |
| The amount of time each hair follicle remains in the anagen phase is genetically determined and finishes with the beginning of the catagen phase. |
| The catagen phase happens at the end of the anagen phase and is a brief transitional stage signalling the end of the active growth of a hair. |
| Alteration of matrix cell activity during anagen, by whatever method chosen, increases the amount of time from removal to regrowth. |
