Understanding the Hair Growth Cycle

Before attempting hair regrowth, it’s essential to understand how hair actually grows. Every hair follicle follows a natural cycle consisting of three main phases:

Anagen (Growth Phase)

This phase lasts between 2 to 7 years. The longer the anagen phase, the longer your hair can grow. Healthy follicles spend most of their time here.

Catagen (Transition Phase)

A short phase lasting a few weeks where hair growth slows and follicles shrink.

Telogen (Resting & Shedding Phase)

Hair eventually falls out, making room for new growth. Excessive shedding occurs when too many follicles enter this phase simultaneously.

Natural hair regrowth focuses on extending the anagen phase and reactivating dormant follicles.

Main Causes of Hair Loss in the USA

Hair loss rarely happens for one reason. In most cases, it’s a combination of internal and external factors.

1. Genetics (Androgenetic Alopecia)

The most common cause of hair loss in American men and women. Genetics affect how sensitive hair follicles are to DHT (dihydrotestosterone).

2. Hormonal Imbalance

Conditions like thyroid disorders, PCOS, menopause, and postpartum changes can disrupt hair growth.

3. Chronic Stress

High cortisol levels push hair into the shedding phase, causing telogen effluvium.

4. Nutritional Deficiencies

Low levels of iron, zinc, biotin, vitamin D, and protein weaken hair follicles.

5. Inflammation & Scalp Issues

Dandruff, fungal infections, and scalp inflammation block follicles and slow growth.
