Running your fingers through your hair and seeing strands fall out can be unsettling. The telogen phase is the natural resting stage of the hair cycle when hair stops growing and prepares to shed. While some shedding is normal, triggers like stress, illness, and hormonal shifts can push more hair into this phase at once.
- The telogen phase is a normal part of the hair growth cycle
- Around 10–15% of your hair is usually in telogen at any time
- Sudden increases can lead to noticeable shedding
- Most telogen-related hair loss is reversible with the right support
Understanding the Hair Growth Cycle
To truly understand the telogen phase, we need to look at the full hair growth cycle. Every hair follicle on your scalp works independently and cycles through four main stages.
Anagen Phase: The Growth Stage
This is the active growth phase. Hair grows about 1 cm per month and can stay in this phase for 2–7 years. Around 80–90% of your scalp hair is usually in anagen.
Longer anagen phases mean longer hair growth potential. Genetics, nutrition, hormones, and overall health influence how long this phase lasts.
Catagen Phase: The Transition Stage
This short phase lasts about 2–3 weeks. The hair stops growing, and the follicle shrinks slightly. Only about 1–3% of hair is in catagen at a given time.
Telogen Phase: The Resting Stage
The telogen phase lasts roughly 2–4 months. During this time:
- The hair follicle is inactive
- The hair strand remains anchored but does not grow
- A new hair begins forming underneath
Normally, about 10–15% of your scalp hair is in telogen.
Exogen Phase: The Shedding Stage
Often considered part of telogen, exogen is when the old hair finally sheds, making room for new growth. Losing 50–100 hairs per day is considered normal.
What Exactly Happens in the Telogen Phase?
In the telogen phase, the follicle enters a resting state. Blood supply and cellular activity reduce significantly compared to the growth phase.
From a dermatological perspective, this is a programmed biological pause. From an Ayurvedic lens, this can be seen as a natural withdrawal of nourishment to the hair (considered an upadhatu of asthi dhatu). When internal balance is maintained, this pause is orderly and temporary.
Problems arise when a larger number of follicles shift into telogen at the same time.
How Much Telogen Hair Is Normal?
Here’s a simplified comparison:
| Hair Cycle Stage | What Happens | % of Hair (Normal) | Duration |
|---|---|---|---|
| Anagen | Active growth | 80–90% | 2–7 years |
| Catagen | Transition | 1–3% | 2–3 weeks |
| Telogen | Resting | 10–15% | 2–4 months |
| Exogen | Shedding | Overlaps telogen | Variable |
If telogen hair exceeds 20–25%, shedding becomes visibly noticeable.
What Triggers Excess Telogen Phase (Telogen Effluvium)?
When many follicles prematurely enter the telogen phase, the condition is called telogen effluvium. This is one of the most common causes of diffuse hair shedding.
Physical Stressors
Major stressors shock the system and shift follicles into rest mode. These include high fever, infections, surgery, rapid weight loss, or childbirth. Postpartum hair loss is a classic example.
Emotional Stress
Chronic stress increases cortisol levels. Elevated stress hormones can disrupt the hair cycle and push follicles into telogen. Poor sleep compounds the effect.
Nutritional Deficiencies
Low iron, protein deficiency, inadequate vitamin intake, and poor gut absorption affect hair growth. Hair is not essential for survival, so during deficiency states, the body diverts nutrients away from follicles.
Hormonal Imbalances
Thyroid dysfunction, PCOS, and sudden hormonal changes can alter the hair cycle. In hypothyroidism, metabolism slows, which affects follicular turnover.
Medications
Certain medications, including some blood pressure drugs and oral minoxidil adjustments, can temporarily increase shedding.
Crash Dieting
Extreme calorie restriction or low-protein diets signal the body to conserve energy. Hair growth is considered non-essential, so follicles enter telogen earlier.
Is Telogen Shedding the Same as Pattern Baldness?
No. Telogen shedding and androgenetic alopecia (pattern hair loss) are different conditions.
| Feature | Telogen Effluvium | Pattern Hair Loss |
|---|---|---|
| Onset | Sudden | Gradual |
| Distribution | Diffuse | Specific areas (crown, hairline) |
| Trigger | Stress/illness | Genetics + DHT |
| Reversibility | Usually reversible | Progressive without management |
However, telogen effluvium can unmask early pattern hair loss.
How to Identify Telogen Phase Hair Loss
Common signs include increased hair fall during washing or combing, hair coming out in clumps, and visible thinning across the scalp rather than just one area.
A simple at-home sign is noticing white bulb-like roots at the end of shed strands, indicating telogen hair.
A dermatologist may perform a hair pull test or recommend blood tests to check iron, thyroid, and vitamin levels.
How Long Does the Telogen Phase Last?
The normal telogen phase lasts 2–4 months. In telogen effluvium, shedding usually begins 2–3 months after the triggering event.
Acute telogen effluvium typically resolves within 3–6 months once the underlying cause is addressed. Chronic telogen effluvium may last longer than 6 months and needs deeper evaluation.
Supporting Hair During the Telogen Phase
Hair retention during telogen depends on reducing triggers and improving internal balance.
Improve Nutritional Intake
Ensure adequate protein, iron, zinc, and essential vitamins. A balanced diet supports anagen re-entry.
Manage Stress and Sleep
Restorative sleep regulates cortisol and supports follicular recovery. Chronic sleep deprivation prolongs the resting stage.
Avoid Aggressive Hair Practices
Tight hairstyles, excessive heat styling, and harsh chemical treatments worsen breakage and create the illusion of more hair loss.
Support Gut Health
Poor digestion affects nutrient absorption. In Ayurveda, impaired agni (digestive fire) reduces tissue nourishment, including hair.
Correct Hormonal Issues
Address thyroid imbalance or PCOS if present. Without correcting the root cause, shedding may persist.
When to Meet a Doctor
Seek medical advice if:
- Shedding continues beyond 6 months
- You notice bald patches
- Hair fall is accompanied by fatigue or weight changes
- There is scalp redness, itching, or pain
Persistent hair fall can signal systemic imbalance.
Common Myths About the Telogen Phase
Many believe cutting hair reduces telogen shedding. It does not affect the follicle.
Frequent shampooing does not cause telogen effluvium; it only dislodges hairs already in exogen.
Oiling alone cannot reverse telogen effluvium if the trigger is nutritional or hormonal.
Gender Differences in Telogen Shedding
Women often experience telogen shedding after childbirth or due to iron deficiency. Men may notice telogen shedding layered over early male pattern hair loss.
In women, hormonal fluctuations play a larger role. In men, genetic sensitivity to DHT may complicate recovery.
Frequently Asked Questions

A Root-Cause Approach: Traya's Perspective
Hair shedding in the telogen phase is rarely just a scalp problem. It reflects internal shifts in nutrition, hormones, stress levels, and metabolic health.
Traya follows a three-science approach combining Dermatology, Ayurveda, and Nutrition. Dermatology evaluates follicle health and clinical triggers. Ayurveda assesses internal imbalances affecting tissue nourishment. Nutrition corrects deficiencies that push follicles prematurely into telogen.
The process begins with a detailed Hair Test to identify underlying causes rather than masking symptoms. This structured evaluation helps personalize care based on your specific triggers, ensuring a more comprehensive and balanced path toward healthier hair cycles.
