You’ve probably noticed that your hair sometimes grows quickly and at other times seems to stop growing altogether.

It happens because every strand of hair follows a natural hair growth cycle, a biological process that controls how hair grows, rests, and sheds over time.

Understanding the stages of the hair growth cycle can help you recognize normal shedding vs. hair loss, improve your hair care routine,s support healthy follicles, and choose treatments that work.

It is one of the most effective ways to maintain stronger, healthier hair.

What Is The Hair Growth Cycle?

The hair growth cycle refers to the continuous biological process that each hair follicle undergoes as hair grows, transitions, rests, and eventually sheds.

Hair follicles cycle through four primary phases:

1. Anagen – Growth phase
2. Catagen – Transition phase
3. Telogen – Resting phase
4. Exogen – Shedding phase

Each hair on your scalp is in a different phase at any given time, which prevents all your hair from shedding at once.

Hair Growth Cycle at a Glance

Hair Growth Stage	What Happens	Typical Duration
Anagen	Active hair growth from the follicle	2–7 years
Catagen	Old hair sheds, and new hair begins growing	2–3 weeks
Telogen	Hair rests without growing	2–4 months
Exogen	Old hair sheds and new hair begins growing	Varies

📊 At any moment, 85–90% of scalp hairs are in the anagen (growth) phase.

Hair Growth Cycle Diagram

A hair follicle progresses through a repeating cycle of growth, transition, rest, and shedding.

The four phases are:

• Anagen – active growth
• Catagen – transition stage
• Telogen – resting phase
• Exogen – shedding phase

🧠 A visual diagram of this cycle helps explain why hair grows continuously while some strands naturally fall out every day.

The 4 Stages of The Hair Growth Cycle

1. Anagen Phase: Active Growth

What it is: The active growth stage of the hair growth cycle

Duration: 2–7 years

What happens: Hair grows from the follicle, fueled by rapid cell division. Up to 85% of your scalp hairs are in this stage at any given time.

Tips for Anagen Growth:

• Eat protein-rich foods
• Avoid excessive heat styling
• Consider professional treatments

💡 Research: Serotonin can activate dermal papilla cells, potentially boosting growth during anagen.

2. Catagen Phase: Transition

What it is: A Short transitional phase of the hair growth cycle

Duration: 2–3 weeks

What happens: Hair stops growing, and the follicle shrinks, preparing for the resting phase.

Tips:

• Avoid harsh brushing
• Limit chemical treatments

3. Telogen Phase: Resting

What it is: Resting phase of the hair growth cycle

Duration: 2–4 months

What happens: Hair is fully formed but not actively growing. Eventually, it will shed naturally.

🧴 Tips:

• Reduce stress
• Maintain gentle hair routines
• Track shedding

4. Exogen Phase: Shedding

What it is: Sometimes considered a separate stage of the hair growth cycle

Duration: Varies

What happens: Old hair sheds naturally, making room for new growth. Normal shedding is 50–100 hairs per day.

🧴 Tips:

• Track shedding patterns
• Support growth with proper nutrition and scalp care.

What Happens If You Ignore Your Hair Cycle

Ignoring your hair’s natural cycle can lead to frustration when hair grows slowly or falls out unexpectedly. Many people confuse normal shedding with hair loss.

If you don’t understand the cycle, you might:

• Apply DIY treatments that don’t match your hair’s needs
• Mismanage scalp stress
• Miss early signs of hair loss. Check out our article on What Is Hair Loss?

Knowing your cycle helps you time treatments, optimize growth, and reduce unnecessary stress.

Factors That Influence Your Hair Growth Cycle

Your hair growth stages follow a natural process, but internal and external factors can influence how long each phase lasts, how often hair sheds, and the overall health of your strands. When disrupted, you might notice increased shedding, slower growth, or hair thinning.

Key Factors:

• Genetics: Determines the length of your Anagen phase, hair texture, and susceptibility to hair loss.
• Hormonal Changes: Pregnancy, menopause, or thyroid fluctuations can push hair into the resting phase, leading to shedding.
• Stress & Emotional Health: Chronic stress can trigger telogen effluvium, disrupting the hair growth cycle.
• Nutrition & Diet: Deficiencies in protein, iron, or biotin can slow growth and weaken follicles.
• Scalp Health: Conditions like dandruff or poor circulation can impair hair growth.
• Medical Conditions & Medications: Autoimmune diseases and certain medications can interfere with the cycle.
• Age: As we age, the Anagen phase shortens, resulting in slower growth and fewer active follicles.
• Hair Care Practices: Excessive heat, harsh chemicals, or tight hairstyles can damage hair and weaken follicles.

🧴 Tip: Supporting your scalp and overall health can help keep your hair cycle balanced and reduce shedding.

How the Hair Growth Cycle Relates to Hair Loss

Hair loss often occurs when the natural hair growth cycle is disrupted.

Common hair cycle disorders include:

• Telogen effluvium
• Androgenetic alopecia
• Alopecia areata

💡 Recognizing early changes in the hair cycle can help identify hair loss conditions sooner.
