The telogen phase is the resting stage of the hair growth cycle, lasting roughly 2-4 months, during which 10-15% of scalp hairs pause growth before shedding as club hairs. Daily hair loss of 50-100 hairs during this phase is normal. Sudden increases point to telogen effluvium, a temporary shedding pattern triggered by stress, illness, or hormonal shifts, typically appearing 2-3 months after the trigger.

# Telogen Phase: What Happens During the Resting Stage of Hair Growth

## What Is the Telogen Phase?

Telogen is the third and final stage of the hair growth cycle, following anagen (growth) and catagen (transition). It lasts roughly 2-4 months for scalp hair. During telogen, follicle activity slows and the strand stops lengthening. At any point, 10-15% of scalp hairs are in this resting stage, which reflects normal ongoing renewal.

- Anagen: active growth phase
- Catagen: short transitional phase
- Telogen: resting phase (2-4 months)
- Exogen: shedding of the club hair

## What Happens Inside the Follicle During Telogen?

The hair produced during anagen matures into a "club hair" and stays anchored in the follicle while it rests. Near the end of telogen, a new anagen hair begins forming beneath the club hair. As the new hair grows, it pushes the old club hair out, a step sometimes labeled the exogen phase.

- Club hair formation
- Follicle rest and reset
- New anagen hair growth beneath it
- Exogen (shedding) step

## What Causes Hair to Enter the Telogen Phase?

Hairs enter telogen mainly because their growth cycle has ended naturally. Aging, hormonal shifts, and seasonal change affect how many follicles rest at once. When a larger share of follicles shift into telogen together, visible shedding called telogen effluvium can occur. Shedding from telogen effluvium usually appears 2-3 months after the trigger event, not right away.

- Physical or emotional stress
- High fever, illness, or major infection
- Surgery or significant blood loss
- Post-pregnancy hormonal shifts
- Rapid weight loss or low protein intake
- Iron deficiency or thyroid imbalance
- Certain medications (some antidepressants, blood pressure drugs)

## How Do You Know You're in the Telogen Phase?

Telogen itself isn't felt, but increased shedding may show up in the brush, shower drain, or on a pillow. Daily hair loss is expected, and wash days often show more shed hair. Club hairs typically have a small white bulb at the root and separate with light tugging. Diffuse thinning across the scalp, rather than a single patch, is the more common pattern.

- Hair comes out easily with gentle tugging
- White bulb visible at the root
- Diffuse scalp thinning
- More noticeable on wash days

## Can You Prevent or Manage Telogen Hair Loss?

Normal telogen cycling can't be prevented and doesn't need to be. Managing avoidable triggers can reduce excess shedding and support regrowth. In telogen effluvium cases, regrowth commonly starts once the underlying trigger is corrected and follicles cycle back into anagen.

- Stress management (walking, mindfulness, yoga)
- Balanced diet: protein, iron, zinc, B vitamins
- Gentle hair care, less heat styling
- Limiting harsh chemical treatments during active shedding
- Medication review with a clinician
- Topical minoxidil when clinically recommended

## When Should You Seek Professional Help?

A professional evaluation is worth considering when shedding is dramatic, continues past a few months, or comes with other symptoms. Blood tests can check for low iron stores, thyroid issues, or other nutritional gaps, guiding targeted treatment.

- Scalp pain, scaling, or burning
- Patchy hair loss
- Thinning eyebrows
- Shedding lasting beyond 3-4 months

## Frequently Asked Questions

### How much hair shedding is normal during telogen?

Daily hair loss of 50-100 hairs is normal. Shedding can look heavier on wash days or with long hair, though the underlying daily count often stays within range.

### Is telogen effluvium permanent?

Telogen effluvium is typically temporary and resolves once the trigger is addressed. Chronic cases can last beyond six months and may need further medical evaluation.

### Are all hairs in the same growth phase at the same time?

No. Each follicle cycles on its own schedule. This is why hair loss doesn't happen all at once and why some strands grow while others rest.

### How long does it take to see regrowth after telogen shedding?

Follicles often return to anagen within a few months. Early regrowth is commonly visible at 3-6 months, with fuller results developing over 6-12 months.

### Do supplements or shampoos help telogen shedding?

Supplements help mainly when a deficiency, such as low iron or zinc, is present. Shampoos can improve scalp comfort but don't stop the telogen phase. A clinician can advise before starting new supplements or treatments.
