Hair Fall Causes in Men & Women + Best Supplements for Hair Growth
By Medorna Editorial · May 2026 · 8 min read · Reviewed by Medorna Wellness Team
Losing 50 to 100 strands of hair a day is entirely normal. The average human scalp has around 100,000 hair follicles, each cycling through growth, transition, and rest phases on its own independent schedule. When this cycle is working as it should, shed hairs are replaced by new ones and overall density stays stable.
The problem begins when shedding consistently outpaces regrowth — when more follicles enter the resting phase than the active growth phase, or when new hairs grow back thinner and weaker than the ones they replaced.
This is the reality of hair fall in men and women: it’s rarely caused by a single factor. Diet, stress, hormones, scalp health, genetics, and the quality of daily hair care all play interconnected roles. Understanding which factors are at work is the first step toward choosing the right response — including which supplements for hair growth are actually worth taking.

The Real Causes of Hair Fall in Men & Women
Hair fall is rarely one-dimensional. Most people experiencing noticeable thinning or shedding are dealing with two or three overlapping triggers simultaneously. Here are the most clinically documented causes:
Nutritional Deficiencies — The Most Overlooked Trigger
Hair follicles are among the most metabolically active cells in the body. They demand a consistent, high-quality supply of amino acids, vitamins, and minerals to sustain the rapid cell division that drives hair growth. When the body is nutritionally depleted — even subtly — the follicle is one of the first systems it deprioritises.
The key nutritional deficiencies linked to hair fall include:
- Iron — carries oxygen to follicles; low ferritin is one of the most common causes of diffuse hair loss in women
- Biotin (Vitamin B7) — essential co-factor for keratin synthesis; the structural protein of the hair shaft
- Zinc — regulates the hair growth cycle and supports sebaceous gland function around the follicle
- Vitamin D — deficiency is strongly associated with alopecia areata and telogen effluvium
- Omega-3 fatty acids — support scalp circulation and reduce inflammatory signals that shrink follicles
- Protein — insufficient dietary protein directly reduces the building blocks available for keratin production
Hormonal Imbalances
In men, the primary hormonal driver of hair loss is dihydrotestosterone (DHT) — a potent androgen derived from testosterone that gradually miniaturises genetically susceptible follicles over years, producing the classic receding hairline pattern of androgenetic alopecia.
In women, hormonal triggers are more varied: post-partum oestrogen withdrawal, thyroid dysfunction (both hypo and hyperthyroidism), polycystic ovarian syndrome (PCOS), perimenopause, and the hormonal shifts associated with starting or stopping oral contraceptives can all push follicles prematurely into the resting phase — resulting in significant diffuse shedding that can persist for months.
Chronic Stress & Telogen Effluvium
Psychological and physiological stress — whether from illness, surgery, significant weight loss, or sustained mental pressure — can trigger a condition called telogen effluvium. In this state, a disproportionate number of follicles simultaneously shift into the resting (telogen) phase and shed their hairs, typically 2–3 months after the triggering event.
The good news: telogen effluvium is usually reversible once the stressor resolves. The challenge is that many people experience it as a sudden, alarming increase in shedding without understanding the delayed connection to an earlier stressful event.
“Most people experiencing noticeable hair fall are dealing with two or three overlapping triggers simultaneously — nutritional gaps, hormonal shifts, and stress rarely arrive alone.”
Scalp Health & Hair Care Habits
The scalp environment directly determines follicle health. Chronic dandruff, seborrhoeic dermatitis, fungal overgrowth, and clogged follicles from product buildup all create inflammatory conditions that impair follicle function over time. Harsh shampoos containing sulphates, frequent heat styling, chemical treatments, and tight hairstyles that pull on the root (traction alopecia) compound this damage.
How Nutritional Deficiencies Directly Damage Hair Follicles
Hair follicles divide faster than almost any other cell type in the human body — producing approximately 0.3–0.4mm of hair shaft per day. This extraordinary rate of cell division demands a continuous, abundant supply of micronutrients. When dietary intake or absorption is inadequate, follicle activity is among the first physiological processes the body scales back in order to prioritise more critical organ functions.
This is why hair fall so often serves as an early visible indicator of a nutritional gap that may not yet be causing other obvious symptoms. By the time hair thinning becomes noticeable, a deficiency has often been building for months.
| Nutrient | Role in Hair Health | Deficiency Sign |
|---|---|---|
| Biotin (B7) | Keratin synthesis; hair shaft structure | Brittle hair, thinning, nail fragility |
| Iron | Oxygen delivery to follicle cells | Diffuse shedding, especially in women |
| Zinc | Hair growth cycle regulation | Patchy loss, slow regrowth |
| Vitamin D | Follicle cycling; receptor activation | Alopecia areata-type shedding |
| Omega-3 (DHA/EPA) | Scalp inflammation control; follicle blood flow | Dry scalp, increased shedding |
| Vitamin A & E | Scalp sebum regulation; antioxidant protection | Dry, flaky scalp; dull, weak hair |
Step 1 — Fix the Foundation: Scalp & Hair Shaft Health
Daily Hair Care · Scalp First
No supplement can compensate for a damaged scalp environment. Before introducing internal support, the foundation — your scalp and the hair shaft itself — needs to be properly maintained. This starts with choosing the right cleansing system.
Most conventional shampoos contain sodium lauryl sulphate (SLS) or ammonium lauryl sulphate (ALS) — aggressive detergents that strip the scalp of its natural lipid barrier, disrupt the microbiome, and leave hair prone to breakage and moisture loss. For anyone experiencing hair fall, switching to a gentler, biotin-enriched formula is a meaningful first intervention.
Avalon Organics Biotin Shampoo — Sulphate-Free Scalp Support
Avalon Organics Biotin B-Complex Shampoo is one of the most trusted imported biotin shampoos available in India — formulated with a blend of biotin, quinoa protein, saw palmetto, and vitamin E in a 100% vegetarian, sulphate-free, GMO-free base.
Why it works for hair fall:
- Biotin and quinoa protein help reinforce the hair shaft to reduce mechanical breakage
- Saw palmetto helps block DHT activity on the scalp — relevant for androgenetic hair loss in both men and women
- Sulphate-free formula cleanses without stripping the scalp’s natural protective moisture barrier
- No parabens, artificial colours, or synthetic fragrances — gentle enough for daily use
Step 2 — Fill the Nutritional Gaps: Daily Multivitamin
Internal Support · Daily Foundation
Because hair fall is so frequently driven by multiple overlapping nutritional gaps, a well-formulated daily multivitamin serves as the most efficient foundation for an internal hair support strategy. Rather than guessing which single nutrient to supplement, a comprehensive multivitamin covers the full spectrum of micronutrients that hair follicles depend on daily.
Vitafusion Multi Vites — Complete Daily Nutrition
Vitafusion Multi Vites is a widely trusted imported adult gummy multivitamin that delivers a complete B-vitamin complex — including biotin — alongside Vitamins A, C, D, E, and essential minerals, all in a convenient, great-tasting gummy format that makes daily compliance effortless.
For hair health specifically, the B-vitamin complex in Vitafusion plays a direct role: B7 (biotin) supports keratin synthesis, B12 supports red blood cell production that carries oxygen to follicles, and folate supports the rapid cell division that drives active hair growth. Together, these create the internal nutritional environment in which healthy follicle function becomes possible.
Step 3 — Target Scalp Inflammation: Omega-3
Anti-Inflammatory · Scalp & Follicle Health
One of the most underappreciated contributors to hair loss is chronic low-grade scalp inflammation. Inflammatory cytokines disrupt the follicle microenvironment, shorten the active growth phase, and — in the case of androgenetic alopecia — amplify the sensitivity of follicles to DHT.
Omega-3 fatty acids, particularly the long-chain DHA and EPA found in marine-source fish oil, are among the most well-researched natural anti-inflammatory compounds available. They work by modulating the production of pro-inflammatory eicosanoids and supporting healthy blood flow to the scalp — ensuring follicles receive the oxygen and nutrients they need during the growth phase.
A clinical study published in the Journal of Cosmetic Dermatology found that women supplementing Omega-3 and Omega-6 fatty acids for six months experienced a significant reduction in hair loss and improvement in hair diameter and density compared to control groups.
Nordic Naturals Ultimate Omega — Clinical-Grade Fish Oil
Nordic Naturals Ultimate Omega is one of the most concentrated and purest Omega-3 supplements available globally. Each serving delivers 1,280mg of EPA + DHA in the natural triglyceride form — the most bioavailable molecular format — making it significantly more effective per softgel than standard fish oil capsules available in India’s domestic market.
For hair health specifically, Nordic Naturals Ultimate Omega delivers:
- High-concentration EPA to reduce scalp inflammatory signals at the follicle level
- DHA to support cell membrane integrity in actively dividing follicle cells
- Third-party verified purity — no heavy metals or oxidised oil
- Lemon flavour — no fishy aftertaste
The Complete Hair Fall Prevention Routine
3-Layer Protocol · Consistent Daily Use
Addressing hair fall effectively requires working on three layers simultaneously: the scalp environment, internal nutritional status, and inflammation control. Here’s how to structure a complete daily protocol:
| Layer | Product | What It Does |
|---|---|---|
| Topical | Avalon Organics Biotin Shampoo | Cleanses without stripping; biotin + saw palmetto directly at the scalp |
| Internal — Base | Vitafusion Multi Vites | Full-spectrum B vitamins, biotin, Vitamin D & A for follicle nutrition |
| Internal — Anti-Inflam | Nordic Naturals Ultimate Omega | Reduces scalp inflammation; improves follicle blood flow and density |
Used consistently for 90–180 days, this three-layer approach addresses the most common root causes of hair fall simultaneously — rather than relying on any single product to do all the work.

Final Thoughts
Hair fall is almost never a single-cause problem — and that’s exactly why single-product solutions so rarely deliver the results they promise. The most effective approach is a layered one: a clean, biotin-rich shampoo that respects scalp health, a comprehensive multivitamin that fills nutritional gaps from within, and a clinical-grade Omega-3 supplement that reduces the inflammation quietly undermining your follicles.
The key is consistency over months, not days. Hair growth cycles are slow — but with the right nutritional environment in place, the results are real and lasting.
