Hair is an essential part of our identity, contributing significantly to our overall appearance and our self-image. By understanding the fascinating journey a hair strand takes from its root to the surface of the scalp, we can unlock the keys to maintaining healthy hair growth. At New Hair Clinic in Perth, we’re looking into the three distinct stages of hair growth, revealing the intricate biological processes at play.

The Hair Growth Cycle: A Continuous Journey

Hair follicles, tiny pockets embedded in the dermis layer of the scalp, are responsible for hair growth. These follicles cycle through three distinct phases, each with a specific function:

Anagen (Growth Phase)

This is the active growth phase, lasting anywhere from 2-7 years for scalp hair. During this time, the hair follicle is highly productive, rapidly dividing cells at the base (papilla) to generate a new hair strand. Blood vessels nourish the papilla, providing essential nutrients and oxygen for hair growth. The length of the anagen phase determines the ultimate length of the hair strand.

Catagen (Transitional Phase)

This brief phase, lasting a few weeks, signifies the end of active growth. The hair follicle begins to shrink and detach from the blood supply, slowing down cell division. The hair strand continues to move up the follicle but is no longer actively growing.

Telogen (Resting Phase)

The final phase lasts about 3 months. The hair follicle lies dormant, and the hair strand remains attached but is no longer anchored to the papilla. Eventually, the hair strand sheds naturally to make way for new hair to begin the cycle again.

It’s important to understand that not all hair follicles are in the same phase at any given time. This ensures a continuous cycle of hair growth and shedding, resulting in a full head of hair.

Our hair grows in three distinct phases. Many things can disrupt these natural stages of hair growth, from genetic and medical conditions to stress and nutritional deficiencies. Book a free hair growth consultation at our Perth clinic.

Factors Influencing the Hair Growth Cycle

Several factors can influence the duration of each stage and the overall health of your hair growth cycle:

• Genetics

  Hair growth patterns and susceptibility to hair loss are often predetermined by genetics. For example, men and women can experience hereditary hair loss in the form of androgenetic alopecia, which is handed down through generations.

• Hormones

  Fluctuations in hormone levels throughout life, such as during pregnancy, childbirth, menopause, or due to certain medical conditions, can impact hair growth and cause temporary hair loss or permanent hair thinning.

• Nutrition

  Deficiencies in essential vitamins and minerals like iron, zinc, and biotin can hinder hair growth.

• Stress

  Chronic stress can disrupt the hair growth cycle, leading to increased shedding.

• Scalp Health

  Inflammatory scalp conditions or improper hair care practices can create an unhealthy environment for hair follicles.

• Age

  Hair growth naturally slows down with age, and the anagen phase typically shortens.

Understanding Hair Loss Through the Natural Hair Growth Cycle

Excessive hair loss occurs when the intricate balance of the natural hair growth cycle is disrupted.

• Premature Transition to Telogen or Resting Phase

  Stress, hormonal fluctuations, nutritional deficiencies, and certain medical conditions can disrupt the normal timing of the hair growth cycle. These factors can prematurely push follicles into the resting phase, resulting in more hairs shedding at once.

• Shortened Anagen or Growth Phase

  Genetics plays a significant role in determining the length of the anagen phase. Androgenetic alopecia, a common form of hair loss in both men and women, is caused by a sensitivity to dihydrotestosterone (DHT), a hormone derived from testosterone.

• Disruption of Blood Flow

  Healthy hair growth requires a steady supply of nutrients and oxygen delivered through the bloodstream. Poor blood circulation to the scalp, potentially caused by certain medical conditions or tight hairstyles that restrict blood flow, can impede hair follicle function and contribute to hair loss.

• Scalp Inflammation

  Inflammatory scalp conditions like seborrheic dermatitis or scalp psoriasis can create an unhealthy environment for hair follicles and disrupt the normal stages of hair growth.

• Scarring

  Scalp injuries, burns, or certain medical procedures can leave scar tissue on the scalp. Scar tissue can permanently damage hair follicles, preventing hair growth in those areas.

FAQs

How fast does hair typically grow?

On average, hair grows about half an inch per month during the anagen phase of the hair growth cycle. However, this rate can vary depending on individual factors like genetics, age, and overall health.

Is it normal to lose hair daily?

Yes, it’s normal to shed 50-100 hairs per day. This is simply the telogen phase of the hair growth cycle at play. However, if you’re noticing significantly more hair loss than usual, it might be a sign of an underlying issue. It’s important to talk to your doctor and, once you have a diagnosis for the underlying cause, to get a free consultation at a leading hair loss clinic to find the best treatment.

What can I do to promote healthy hair growth?

Maintaining a balanced diet rich in essential nutrients, managing stress levels, and practising gentle hair care techniques are all beneficial for healthy hair follicles and supporting the stages of hair growth.

What are some treatment options for hair loss?

Depending on the cause of hair loss, various treatments like hair loss medications, PRP therapy, mesotherapy scalp treatments, or hair transplant surgery can be explored. Consulting a qualified hair loss specialist is essential for determining the best course of action.

Is it true that cutting your hair can make it grow faster?

Cutting your hair does not actually accelerate hair growth. Human hair growth occurs at the root (in the hair follicle itself), not the ends where it is essentially dead. However, regular trims can remove split ends from the hair shaft and prevent further damage, giving the appearance of healthier, fuller hair.
