Hair is a defining feature of our appearance and self-esteem. We all desire healthy, luscious locks, but understanding the stages of hair growth is essential to achieve that goal.
In this blog, we’ll explain the intricacies of the 3 phases of hair growth – the anagen phase, catagen phase, and telogen phase. We’ll also explore how these 3 stages of hair growth influence hair loss, including male and female pattern baldness.
What is Meant by the Stage of Hair Growth?
Before we go into the specific phases, let’s clarify what we mean by the “stage of hair growth.” Hair growth is a cyclical process, and these stages describe where individual hairs are in that cycle. These stages affect the thickness, length, and overall health of your hair.
What Are the Stages of Hair Growth?
The 3 stages of hair growth are:
1. Anagen Phase
- The anagen phase is the active growth phase of hair, basically when the hair grows. During this phase, hair follicles are busy producing new cells, resulting in the rapid lengthening of your hair.
- Hair can remain in the anagen phase for anywhere from 2 to 7 years, depending on various factors such as genetics, age, and overall health.
- The longer the anagen phase, the longer your hair can grow, making this phase crucial for achieving long, healthy locks.
2. Catagen Phase
- The catagen phase is a transitional stage that follows anagen. It’s a relatively short phase, lasting only a few weeks.
- During catagen, hair growth slows down, and the hair follicle detaches from the blood supply. This leads to the formation of a club hair, which is the root of a new hair.
- While the hair is no longer actively growing during catagen, it remains firmly anchored in the hair follicle.
3. Telogen Phase
- Telogen stage is the final phase of the hair growth cycle, where hair is at rest (resting phase).
- During this stage, the old hair is shed, making way for new hair growth to begin.
- On the scalp, approximately 10-15% of hair is in the telogen phase at any given time.
What Influences Hair Growth Cycles?
The duration and health of your hair growth cycles are influenced by a multitude of factors, each of which plays a pivotal role in determining the condition of your locks. Here’s a deeper look at some of these key influencers:
- Genetics: The genetic blueprint you inherit from your family has a significant impact on your hair growth. It dictates not only the potential length of your anagen phase but also the likelihood of experiencing conditions like male and female pattern baldness.
- Age: As we age, our hair growth cycles naturally change. Hair growth tends to slow down, and the anagen phase may become shorter. This is why older individuals often notice thinner or grayer hair.
- Hormones: Hormones, particularly androgens, can have a substantial influence on hair growth. In conditions like androgenetic alopecia, DHT (dihydrotestosterone), a byproduct of testosterone, can shrink hair follicles and lead to shorter anagen phases.
- Environmental Factors: External conditions and habits also come into play. Excessive heat styling, frequent use of chemical treatments, and exposure to environmental pollutants can weaken hair and influence the duration of the anagen phase.
Hair Growth Cycle and Male Pattern Baldness
Male pattern baldness, also known as androgenetic alopecia, is a common condition that affects many men. It is primarily influenced by the hormone dihydrotestosterone (DHT), which shortens the anagen phase. This results in finer and shorter hair that eventually stops growing altogether. Understanding the stages of hair growth is crucial in tackling male pattern baldness and seeking appropriate treatments.
Hair Cycle and Female Pattern Baldness
Women can also experience pattern baldness, characterised by diffuse thinning of the hair. Although the causes may differ from male pattern baldness, the stages of hair growth still play a pivotal role. Understanding these stages can help women address hair loss concerns and explore effective solutions.
In conclusion, the stages of hair growth are a fascinating journey within your follicles that determine the quality and longevity of your hair. Understanding these stages is crucial in addressing hair loss concerns and maintaining the health and vitality of your locks.
