Understanding Hair Loss: Causes, Mechanisms & Effective Treatments

A complete guide to hair loss causes and how Hairevive provides a one-stop solution for healthier, fuller hair.

What is Hair Loss?

Hair loss, or alopecia, affects both men and women and can present as thinning, increased shedding, or complete loss in certain areas. While some hair shedding is normal—typically 50 to 100 hairs per day—excessive or persistent loss often reflects underlying hormonal, metabolic, or environmental factors affecting the hair growth cycle. Understanding the root causes is essential for effective treatment and recovery.

The Hair Growth Cycle

Hair follicles cycle through three key phases that determine hair health and density:

The Hair Growth Cycle: Anagen, Catagen, Telogen

🌱 Anagen (Growth Phase)

Lasts 2–6 years and determines hair length and density. During this phase, hair grows actively and is most visible. This is the longest phase of the hair cycle.

⏸️ Catagen (Transition Phase)

A short phase lasting 2–3 weeks where growth slows and the follicle begins to shrink. Hair stops growing but remains in place.

💤 Telogen (Resting Phase)

Lasts 2–3 months. Hair sheds and new growth begins beneath. Disruption of this cycle—particularly shortening of the anagen phase—leads to visible thinning.

Common Causes of Hair Loss

Five Main Causes of Hair Loss

1. Hormonal Imbalance

Hormones play a central role in hair growth. Conditions such as PCOS, menopause, postpartum changes, and thyroid disorders can significantly impact follicle function and hair cycling.

2. DHT and Androgenic Alopecia

Dihydrotestosterone (DHT) is a key driver of male and female pattern hair loss. It binds to genetically susceptible follicles, causing miniaturization and shortening of the anagen phase.

3. Stress and Telogen Effluvium

Physical or emotional stress can push a large number of hairs into the telogen phase, leading to sudden shedding. This condition is often reversible with stress reduction.

4. Nutritional Deficiencies

Low levels of iron, zinc, vitamin D, and protein can impair hair growth and follicle health. These nutrients are essential for keratin synthesis and follicle function.

5. Metabolic & Inflammatory Conditions

Metabolic syndrome, insulin resistance, and chronic inflammation can negatively affect follicle cycling and scalp health, accelerating hair loss.

The Role of Follicle Health

Healthy hair depends not only on hormones but also on the structural integrity of the follicle. Research has shown that changes in the arrector pili muscle, which anchors the follicle and increases circulation, are associated with irreversible hair thinning and follicle miniaturization. Maintaining follicle health is therefore crucial for long-term hair preservation.
