• The phases "The hair growth cycle" (SMP)

The hair growth cycle is indeed a very intricate and complex biological process, consisting of three main stages: the growth phase, the transitional phase, and the resting phase. Throughout these stages, the speed and characteristics of hair growth are influenced by various factors such as genetics, hormones, nutritional status, overall health, and external environmental influences. Each phase of the hair growth cycle repeats throughout a person's lifetime, and understanding these patterns is crucial for comprehending the process of hair growth and shedding.

1. Anagen Phase (Growth Phase):

   • This is the active phase of hair growth.
   • Lasts typically between 2 to 7 years.
   • Hair grows approximately 1 centimeter per month.
   • At any given time, about 85-90% of hair is in this phase.

2. Catagen Phase (Transitional Phase):

   • The hair follicle begins to shrink.
   • This phase lasts about 10 days.
   • Hair growth slows and the hair detaches from the blood supply.

3. Telogen Phase (Resting Phase):

   • The hair follicle is completely at rest.
   • Lasts around 3 to 4 months.
   • The hair doesn't grow but stays attached to the follicle.
   • Approximately 10-15% of all hairs are in this phase.
   • At the end of the telogen phase, hair naturally sheds, leading to the start of a new anagen phase, and the cycle repeats.

Understanding this cycle can be important for recognizing normal hair growth patterns and identifying any potential hair growth issues.
