Understanding Hair Growth Stages and Normal Hair Loss – Hair Loss Awareness Month

Hair loss is a topic that concerns many of us, but how much hair loss is actually considered normal? It’s a question that can be tricky to answer, as hair shedding is a natural part of the hair growth cycle. Understanding these cycles and recognizing the signs of abnormal hair loss can help you maintain healthy hair and seek appropriate treatment if necessary. In this blog, we’ll explore the stages of hair growth, what constitutes normal hair loss, and when you should consider seeing a specialist.

The Hair Growth Cycle

Hair growth occurs in a cyclical pattern, with each strand of hair undergoing four distinct stages:

Anagen (Growth Phase): The anagen phase is the active growth period for hair follicles. During this phase, cells in the root of the hair divide rapidly, and the hair strand is formed and pushes out from the follicle. The anagen phase can last anywhere from two to seven years, depending on genetics, and determines the length of your hair.

Catagen (Transitional Phase): Following the anagen phase, the hair enters the catagen phase, a short transitional period that lasts about two to three weeks. During this phase, hair growth stops, and the outer root sheath shrinks and attaches to the root of the hair, forming what is known as club hair.

Telogen (Resting Phase): The telogen phase is the resting period for hair follicles and lasts around three months. During this phase, the hair is fully formed but not actively growing. About 10-15% of your hairs are in this phase at any given time.

Exogen (Shedding Phase): The exogen phase is sometimes considered a part of the telogen phase but is distinct in that it’s when the hair is actually shed from the scalp. This phase overlaps with the anagen phase, as new hair begins to grow in the follicle while the old hair is shed. Shedding 50-100 hairs daily during this phase is normal and part of the natural hair renewal process.

What is Considered Normal Hair Loss?

“Normal” hair loss typically involves shedding 50-100 hairs per day. This may sound like a lot, but considering the average person has about 100,000 hair follicles on their scalp, this amount of shedding is negligible. Normal hair loss can manifest as a few strands of hair on your pillow, in your shower drain, or on your comb.

As you age, you may also notice a gradual decrease in hair density or a slight receding hairline. This type of hair loss is often related to the natural aging process and is usually not a cause for concern.

Signs of Abnormal Hair Loss

While some hair loss is normal, excessive hair shedding or noticeable thinning can be a sign of an underlying issue. Here are some red flags to watch out for:

Increased Shedding: Losing more than 100 hairs per day or noticing significant hair clumps in your comb or shower drain could indicate abnormal shedding.

Sudden Hair Loss: If you experience sudden hair loss in patches or see a significant decrease in hair density, it’s time to book a consultation.

Changes in Hair Growth: Fluctuations in hair shedding may occur throughout your menstrual cycle, but prolonged periods of increased shedding should not be ignored.

Causes of Abnormal Hair Loss

There are numerous factors that can contribute to abnormal hair loss, including:

Genetics: A family history of hair loss can increase your risk of developing the condition.

Hormonal Imbalances: Sensitivity to androgens (male hormones), changes in birth control, or conditions like polycystic ovary syndrome (PCOS) can affect hair growth.

Nutritional Deficiencies: A lack of essential nutrients, such as protein, can weaken hair follicles and lead to hair loss.

Stress and Trauma: Physical or emotional stress, including sudden weight loss or illness, can trigger excessive shedding.

Medical Conditions: Thyroid issues, diabetes, and other health problems can disrupt the normal hair growth cycle.

Postpartum Hair Loss: Many women experience increased shedding after giving birth due to hormonal changes.

Medications: Certain medications, including those for cancer, depression, and high blood pressure, can cause hair loss as a side effect.

Effective Treatments for Hair Loss

If you’re experiencing gradual, age-related hair loss, PRP (Platelet-Rich Plasma) Hair Restoration can be an effective therapy to stimulate hair growth. PRP involves injecting a concentration of your own platelets into the scalp, which releases growth factors and promotes hair regrowth.

However, if you’re dealing with increased hair shedding or sudden hair loss, it’s crucial to address the root cause first. Dr. Wendy Tao, a licensed Naturopathic Doctor, is highly skilled in identifying and treating the underlying causes of hair loss. She emphasizes a holistic approach, focusing on overall wellness to improve both internal health and external appearance.

Why Addressing the Root Cause is Important

While treatments like Rogaine or Rosemary Oil can be tempting, they may not provide lasting results if the underlying cause of hair loss isn’t addressed. By focusing on wellness and working with a naturopathic doctor, you can develop a comprehensive treatment plan that not only slows hair shedding but also promotes healthy, sustainable hair growth.

When to Seek Help for Hair Loss

Hair loss, whether gradual or sudden, can be distressing. If you’re concerned about your hair shedding, it’s important to seek professional advice. Understanding the hair growth cycle and recognizing the signs of abnormal hair loss can help you take proactive steps toward maintaining healthy hair.

Remember: All hair loss is challenging, but with the right support and treatment plan, you can manage it effectively. During Hair Loss Awareness Month, take the time to evaluate your hair health and consider consulting with a specialist to ensure your hair remains as healthy as possible.
