The 4 Phases of Hair Growth
Before breaking down the various factors that play into hair thinning, shedding, and hair loss… it is important to understand the hair growth cycle. There are 4 different phases of the growth cycle and each hair follicle acts independently. This means that each follicle is in a different stage of its own growth cycle almost acting like its own “mini organ”.
Each follicle is either growing, transitioning, resting, or shedding at any given time which explains why minimal shedding (50-100 hairs per day) is considered normal. During healthy hair growth… 80-85% of the follicles on your head are actively growing. However, when the hair growth phases are disrupted - the anagen “growth” phases can shorten and telogen “resting” phases can lengthen.
The Hair Growth Cycle also illustrates why certain treatments may take several months to show results and why consistent use of treatments is crucial. Follicles are always shifting through the 4 phases and need consistent nourishment for healthy hair growth.
