Hair Loss: Identifying the Type and Treatment

Step 1 - Identify the Likely Type

Step 2 - Rule Out Reversible Causes First

• Thyroid function (TSH) - hypothyroidism and hyperthyroidism both cause hair loss
• Iron/ferritin - iron deficiency is a leading cause of diffuse shedding in women
• CBC - to rule out anemia
• Androgens - if signs of excess (acne, irregular periods, hirsutism) in women
• Recent stressors - illness, surgery, weight loss 3-6 months prior (telogen effluvium lag)
• Medications - review the drug list above

Step 3 - Treatment by Type

Androgenetic Alopecia (most common)

• Topical minoxidil (2% or 5%) - applied to the scalp daily; FDA-approved for both men and women; extends the anagen (growth) phase. Oral low-dose minoxidil (0.25-2.5 mg/day) is now widely used and shown by recent meta-analysis to be as effective or superior to topical (PMID 39425514)
• Finasteride (1 mg/day oral, men) - blocks DHT production via 5α-reductase type 2; highly effective. A 2025 network meta-analysis confirms finasteride + minoxidil together outperform either alone (PMID 40586152)
• Dutasteride (0.5 mg/day, men) - blocks both type 1 and type 2 5α-reductase; more potent than finasteride

• Topical minoxidil (first-line)
• Spironolactone (anti-androgen) - especially if signs of hyperandrogenism
• Cyproterone acetate (where available) - shown more effective than minoxidil when hyperandrogenism, high BMI, or irregular periods are present
• Finasteride has limited benefit in women and is contraindicated in pregnancy

• Platelet-rich plasma (PRP) - intradermal injections; role still being defined but shows promise
• Microneedling - a 2025 meta-analysis shows combined microneedling + minoxidil outperforms minoxidil alone (PMID 40056230)
• Hair transplantation - micrografts from occipital area; best for stable, advanced cases

Telogen Effluvium

• Largely self-limiting (resolves in 3-6 months once trigger is removed)
• Correct the underlying cause: treat thyroid disease, replenish iron/ferritin (aim ferritin >70 ng/mL), improve nutrition, manage stress
• Minoxidil can help speed regrowth

Alopecia Areata

• Intralesional corticosteroids (triamcinolone acetonide) - first-line for patchy disease
• Topical corticosteroids or topical minoxidil as adjuncts
• JAK inhibitors (baricitinib, ritlecitinib) - FDA-approved for moderate-to-severe cases; represent a major recent advance

Practical Next Steps

1. See a dermatologist for a pull test, dermoscopy, and possibly a scalp biopsy to confirm the type
2. Get baseline labs: TSH, ferritin, iron, CBC, androgens (if female with signs of excess)
3. Photograph the scalp regularly to track progression and treatment response
4. Avoid harsh hair treatments, tight hairstyles, and excessive heat

Note: This image alone cannot confirm a diagnosis. The pattern of loss on the scalp (not just the shed hair) is needed for accurate classification. A dermatologist evaluation is strongly recommended - especially since the amount of hair in the image suggests significant loss.

Diffuse Hair Loss - Diagnosis & Treatment

Two Main Causes of Diffuse Shedding

Telogen Effluvium - Common Triggers

• Major illness, surgery, or high fever
• Childbirth (postpartum effluvium - very common)
• Rapid weight loss / crash dieting
• Severe psychological stress
• Iron/ferritin deficiency - found in 30-47% of TE patients; the single most common nutritional cause
• Thyroid disease (hypo or hyper)
• Drugs: warfarin, heparin, beta-blockers, lithium, isotretinoin, interferons, propylthiouracil
• Scalp disorders (seborrheic dermatitis, psoriasis of the scalp)

Workup - What to Test

Treatment

For Telogen Effluvium

1. Reassurance - up to 80% resolve spontaneously within 3-6 months once the trigger is removed. Hair regrows at ~1 cm/month.
2. Treat the underlying cause:
   • Iron supplementation if ferritin is low (supplement to >70 ng/mL)
   • Thyroid hormone replacement if hypothyroid
   • Treat scalp inflammation (seborrheic dermatitis - ketoconazole or zinc pyrithione shampoo)
   • Stop offending drug if possible
3. Diet - ensure adequate protein (hair is keratin), zinc, biotin, and iron
4. Topical minoxidil (5%) - can help accelerate regrowth in chronic TE (lasting >6 months); note it may initially cause a brief extra shed as telogen hairs are released to trigger new anagen

For Diffuse Androgenetic Alopecia

Practical Timeline

Trigger → 2-5 months → Peak shedding
Stop trigger → 2-3 months → Shedding slows
→ 3-6 months → Visible regrowth begins
→ 12-18 months → Full recovery (if TE)

When to See a Dermatologist

• Shedding beyond 6 months with no clear trigger
• Positive family history of early baldness
• Signs of androgen excess in women
• Patchy loss within the diffuse shedding (may suggest concurrent alopecia areata)
• No improvement after addressing nutritional deficiencies

Anti-Hairfall Shampoos - Best Available in India

Tier 1 - Medical/Medicated (Most Effective)

How to use medicated shampoos: Apply, leave on scalp for 3-5 minutes, then rinse. Use 2-3x per week, not daily. Alternate with a mild shampoo on other days.

Tier 2 - OTC Anti-Hairfall (Gentle, Daily Use)

Tablets / Oral Medicines That Reduce Hair Shedding

Prescription Medicines (Need a Doctor)

These require a dermatologist prescription. Do not self-medicate with finasteride or spironolactone.

OTC Supplements (Safe Without Prescription)

Most Practical Recommendation Based on Your Case (Diffuse Shedding)

Important: Shampoo alone will not stop shedding caused by nutritional deficiency, thyroid disease, or androgenetic alopecia. Treat the root cause alongside a good shampoo for best results. Follihair + Nizoral + checking ferritin/TSH is the most cost-effective starting point for most people in India.

What is AnaGain?

How It Works - The Science

Clinical Evidence

Normal A:T ratio is 12:1 in healthy scalp. Hair loss patients typically have 4:1 or lower. A ratio above 5 is considered normal. Getting from 4 to 7.2 in 3 months is a meaningful shift.

Best AnaGain-Containing Products Available in India

Serums / Sprays (Topical - Best Route)

Best value pick: Minimalist Hair Growth Actives 18% - highest concentration of AnaGain + 4 other proven actives in one bottle, widely available on Nykaa, Amazon India, beminimalist.co

How to Use AnaGain Spray/Serum Correctly

1. Apply to dry or towel-dried scalp - not on hair strands
2. Section the hair, apply directly to scalp in areas of thinning
3. Do NOT rinse off - leave-on formula is essential (rinse-off shampoos won't deliver enough contact time)
4. Massage gently for 2-3 minutes to improve absorption
5. Use twice daily (morning + night) for best results per the clinical protocol
6. Minimum 3 months of consistent use before judging results - hair cycle is slow

AnaGain vs Other Actives - Quick Comparison

Bottom Line

1. Minimalist Hair Growth Actives 18% serum (AnaGain + Redensyl + Procapil + Capixyl + Baicapil) - apply to scalp twice daily
2. Nizoral/Scalpe Plus shampoo 3x/week for scalp health
3. Follihair tablets (OTC) for nutritional support
4. Check ferritin + TSH - the most overlooked reversible causes
5. If no improvement in 3 months → see dermatologist for oral minoxidil (this remains the most evidence-backed oral option for diffuse shedding)

Anti-Hairfall Sprays in India - Complete List

Category 1 - Minoxidil Sprays (Strongest, Most Evidence-Backed)

How to use: Apply directly to scalp (not hair), 1 ml twice daily (morning + night). Do NOT rinse off. Takes 3-6 months to see results. Must be used continuously - stopping causes shedding to return.

Minoxidil sprays require a prescription from a dermatologist in India, though many are available OTC at pharmacies.

Category 2 - Natural Active Sprays (No Prescription Needed)

Category 3 - Ayurvedic / Herbal Sprays

Which One Should You Choose?

Significant diffuse shedding
         ↓
First check: Ferritin + TSH (blood tests)
         ↓
Treat deficiency → + Nizoral shampoo (3x/week)
         ↓
START: Minimalist 18% serum (spray on scalp) → 8 weeks
         ↓
No improvement?
         ↓
See dermatologist → Mintop/Tugain 5% Minoxidil spray
         + Oral minoxidil 0.5-2.5mg (women) / 2.5-5mg (men)

Key Rules for Any Spray

1. Apply to scalp only - not on hair lengths
2. Leave on - never wash off within 4 hours of application
3. Use consistently - skipping days ruins the result
4. Part hair first in 2-3 sections for even coverage
5. Massage gently for 1-2 minutes after applying
6. Morning + night = best results (especially for minoxidil)

Most recommended starting combo for India: Minimalist 18% serum (spray on scalp, twice daily) + Nizoral shampoo (3x/week) + Follihair tablet daily. If no improvement in 3 months, escalate to Mintop Forte 5% spray under dermatologist supervision.
