Hair Loss Treatment India: Test Before You Treat

Hair Loss Root Causes

6 causes of hair loss in Indian men

Each cause has different biomarkers, prevalence, treatments, and timelines to recovery. Testing identifies which you have.

Hair Loss Cause	Prevalence in Indian Men	Key Biomarkers	Primary Treatment	Response Time
DHT-Driven (Androgenetic)	30–35%	DHT, Free T, Androgen sensitivity	Finasteride or Minoxidil	4–6 months
Iron Deficiency	28–32%	Serum ferritin, Hemoglobin, TIBC	Iron supplementation	12–16 weeks
Thyroid Dysfunction	28–32%	TSH, Free T3, Free T4, TPO antibodies	Levothyroxine or Antithyroid drugs	8–12 weeks
Vitamin D Deficiency	70–85% (widespread in India)	25(OH) Vitamin D	Vitamin D3 supplementation	8–12 weeks
Elevated Prolactin	8–12%	Serum prolactin, TSH	Cabergoline or treat underlying cause	6–8 weeks
Nutritional (Protein, Zinc, B12)	15–20%	Total protein, Zinc, B12, Folate	Dietary changes + supplementation	8–12 weeks

Treatment Decision Matrix

If biomarker → Then treatment → Timeline

If Biomarker Result	Then Treatment	Expected Timeline
DHT elevated + Androgenetic pattern	Finasteride 1mg daily + Minoxidil 5% topical	4–6 months to see regrowth
Ferritin <30 ng/mL (Iron deficiency)	Iron supplementation 325mg ferrous sulfate daily	12–16 weeks (monitor monthly)
TSH >4 mIU/L (Hypothyroidism)	Levothyroxine starting 25–50 mcg daily	8–12 weeks (retest at 6–8 weeks)
TSH <0.5 mIU/L (Hyperthyroidism)	PTU or Methimazole (dose varies)	8–12 weeks after euthyroid state
Vitamin D <20 ng/mL (Severe deficiency)	Vitamin D3 4000–10,000 IU daily	8–12 weeks (monitor at 6 weeks)
Prolactin >25 ng/mL	Cabergoline 0.25–0.5 mg 2x weekly	6–8 weeks to normal levels
B12 <200 pg/mL or Folate <4 ng/mL	B12 IM 1000 mcg monthly + Folate 5mg daily	6–8 weeks
Zinc <60 mcg/dL	Zinc gluconate 30mg elemental zinc daily	6–8 weeks

Questions

Frequently asked about hair loss

What causes hair loss in men?

Hair loss has multiple causes: DHT-driven androgenetic alopecia (60% of men by 35), iron deficiency, thyroid dysfunction, vitamin D deficiency, elevated prolactin, and nutritional deficiencies. Only DHT-driven loss responds to Finasteride. Without testing, you won't know which cause you have, leading to ineffective treatment and wasted time.

Does Finasteride work for hair loss?

Finasteride blocks DHT production and is effective for androgenetic alopecia — but only if your hair loss is actually DHT-driven. Studies show only 30% of hair loss in men is purely DHT-driven. If thyroid, iron, or prolactin issues are causing your loss, Finasteride will not help. Testing first saves you from 6-12 months of ineffective treatment.

Can thyroid cause hair loss?

Yes. Hypothyroidism and hyperthyroidism both cause diffuse hair shedding by disrupting the hair growth cycle. TSH abnormalities alter metabolism and nutrient absorption critical for hair follicle health. Thyroid-related hair loss affects 30% of men with hair loss. Treating the underlying thyroid condition often reverses shedding within 8-12 weeks.

What is the best blood test for hair loss?

Comprehensive testing includes: DHT and free testosterone (androgen sensitivity), ferritin (iron stores), TSH and free T3/T4 (thyroid function), vitamin D (follicle health), and prolactin (hormone-driven loss). A single biomarker test misses root causes. arq. tests all six markers plus 100+ biomarkers to identify exactly what's causing your hair loss.

Is Minoxidil safe long-term?

Minoxidil is generally safe for long-term use when applied topically. It works as a vasodilator, improving blood flow to hair follicles. However, it doesn't address root causes — if iron or thyroid deficiency is driving loss, Minoxidil alone won't stop it. Combining Minoxidil with targeted treatment of underlying causes yields better outcomes.

What is the best hair loss treatment in India?

The best treatment is one based on your specific biomarkers, not a generic protocol. arq. combines blood testing (DHT, ferritin, thyroid, vitamin D, prolactin), physician assessment, and personalized treatment. Whether Finasteride, Minoxidil, iron supplementation, or thyroid treatment, your protocol is built on your data — leading to faster results and fewer side effects.

Does iron deficiency cause hair loss?

Iron deficiency is the #2 cause of hair loss in India. Low ferritin impairs hemoglobin production, reducing oxygen delivery to hair follicles and disrupting the growth cycle. Hair loss from iron deficiency is diffuse and often overlooked. Correcting ferritin from 11 to 68 ng/mL typically stops shedding within 12-16 weeks.

How does arq. treat hair loss differently?

arq. tests before prescribing. Most platforms sell Minoxidil and supplements on a questionnaire, never testing DHT, thyroid, iron, or prolactin. If your hair loss is thyroid-driven, Finasteride does nothing. arq.'s protocol identifies the root cause through 100+ biomarkers and assigns a physician to ensure your treatment targets what's actually causing your hair loss.

Key Takeaways

→ Test before you treat: 70% of men with hair loss are NOT DHT-driven. Starting Finasteride without bloodwork wastes 6–12 months and side effects without addressing the actual cause.
→ Iron deficiency is the #2 cause: In India, 28–32% of hair loss is driven by low ferritin. Correcting iron from 11 to 68 ng/mL stops shedding within 12–16 weeks — faster than any DHT blocker.
→ Thyroid affects 30% of hair loss cases: TSH abnormalities disrupt the hair growth cycle. If hypothyroidism is the cause, Levothyroxine restores hair growth in 8–12 weeks — Finasteride does nothing.
→ Vitamin D deficiency is widespread in India: 70–85% of Indian men have low vitamin D, which disrupts follicle stem cells. Supplementation (4000–10,000 IU daily) reverses hair loss in 8–12 weeks.
→ Personalized protocols work faster: Testing 6 biomarkers (DHT, ferritin, TSH, free T3/T4, vitamin D, prolactin) identifies your root cause and allows your physician to prescribe only what your blood says you need — no guessing, faster results, fewer side effects.
