Why Is Your Hair Shedding? Understanding Telogen Effluvium and PRP Treatment

Hair shedding is a normal part of the hair growth cycle—most people lose around 50–100 hairs per day. However, if you notice clumps of hair on your pillow, in the shower drain or an overall thinning of your hair, it may signal an underlying issue. One common cause is telogen effluvium, a type of temporary hair loss often triggered by stressors to the body. In this guide, we'll explain why hair sheds, what telogen effluvium involves, how PRP for telogen effluvium may help, and what medical next steps you can take.

1. Common Reasons for Increased Hair Shedding

Hair growth follows three phases:

• Anagen (growth)
• Catagen (transition)
• Telogen (resting and shedding)

When more hairs than usual enter the telogen phase at once, you experience noticeable shedding. Common triggers include:

• Physical or emotional stress
• Illness or surgery
• Hormonal shifts (postpartum, thyroid issues, menopause)
• Nutritional deficiencies (iron, protein, vitamin D)
• Certain medications (retinoids, blood thinners, antidepressants)
• Rapid weight loss or restrictive diets
• Chronic illnesses (autoimmune diseases, severe infections)

Typically, shedding begins 2–3 months after a trigger and may last up to six months. Recognizing the cause is key to effective treatment.

2. What Is Telogen Effluvium?

Telogen effluvium (TE) is a diffuse, non-scarring hair loss where a sudden shift in the hair cycle pushes hairs into the resting (telogen) phase. Features of TE:

• Diffuse thinning over the entire scalp rather than in patches
• Sudden onset of noticeable shedding
• Often reversible once the trigger is removed

Because TE is not permanent, hair usually regrows within 6–12 months once the underlying cause is addressed.

3. PRP for Telogen Effluvium: How It Works

Platelet-rich plasma (PRP) therapy harnesses your body's own healing factors to stimulate hair growth:

1. Blood draw: A small amount of your blood is taken.
2. Centrifugation: The blood is spun to concentrate platelets.
3. Injection: The platelet-rich plasma is injected into areas of thinning scalp.

Platelets release growth factors that:

• Encourage blood vessel formation (angiogenesis)
• Activate stem cells in hair follicles
• Extend the anagen (growth) phase

Evidence and Expectations

• Multiple small studies show increased hair density and thickness after PRP for telogen effluvium.
• Results vary; some patients see improvement in 3–6 months.
• Maintenance sessions every 3–6 months may be needed.

While PRP is promising, it's not magic. It works best when combined with correction of underlying triggers (e.g., nutrition, hormone balance).

4. Medical Next Steps: Diagnosis and Treatment Plan

If you suspect telogen effluvium, these are the typical medical steps:

1. Detailed History and Exam

   • Onset and pattern of shedding
   • Recent illnesses, surgeries, stressors
   • Diet, medications, family history of hair loss

2. Basic Laboratory Tests

   • Complete blood count (CBC)
   • Ferritin (iron stores)
   • Thyroid-stimulating hormone (TSH)
   • Vitamin D levels
   • Hormone panels (if indicated)

3. Scalp Examination

   • Dermoscopy to rule out scarring alopecia
   • Pull test (gently tugging small sections of hair)

4. Address Underlying Causes

   • Correct nutritional deficiencies
   • Adjust or change medications if possible
   • Manage stress (see next section)

5. Consider PRP for Telogen Effluvium

   • Discuss the benefits, risks and costs with a hair-restoration specialist
   • Ensure the clinic follows strict sterile protocols

6. Other Treatment Options

   • Topical minoxidil
   • Low-level laser therapy
   • Hormonal treatments (for women with androgen excess)

Always review all options with a board-certified dermatologist or hair-restoration expert.

5. Lifestyle and Self-Care Strategies

Complement medical treatments with healthy habits:

• Balanced diet rich in lean protein, iron, zinc and vitamins A, C, D, and E
• Gentle hair care: avoid tight styles, harsh chemicals and excessive heat
• Stress management: meditation, yoga, breathing exercises
• Adequate sleep: aim for 7–9 hours per night
• Regular follow-up: track shedding patterns and adjust interventions

These measures support overall hair health and can speed recovery from TE.

6. When to Seek Immediate Help

Though telogen effluvium itself is not life threatening, serious conditions can mimic hair shedding:

• Rapid, patchy hair loss (alopecia areata)
• Signs of infection (redness, pain, pus) on the scalp
• Unexplained weight loss, fatigue, fevers
• Severe nutritional deficiencies

If you experience any of these alongside your hair loss, get a professional assessment. To better understand what might be causing your symptoms and whether you need urgent care, you can check your symptoms with a free AI-powered tool to help determine your next steps.

7. Key Takeaways

• Hair shedding becomes noticeable when many hairs enter the telogen (resting) phase at once.
• Telogen effluvium is often triggered by stress, illness, hormone changes or nutrition issues.
• PRP for telogen effluvium uses your own platelets to stimulate hair-growth signals and may improve density.
• A thorough workup—history, labs, scalp exam—is essential to rule out other causes.
• Lifestyle steps (diet, hair care, stress management) support recovery.
• Always discuss serious or sudden changes with your healthcare provider.

Hair shedding can be distressing, but with a systematic approach—identifying triggers, pursuing evidence-based treatments like PRP, and maintaining healthy habits—you can often restore a fuller, healthier mane. If you're concerned about your symptoms or notice warning signs, please speak to a doctor right away.
