Hair is more than just strands growing from the scalp. It reflects health, identity, and confidence. That’s why the sight of hair on a pillow, comb, or shower drain can be worrying. For many people, the immediate thought is:
“Am I losing too much hair?”
The truth is that some degree of hair shedding is completely natural. Each hair follicle follows a biological cycle of growth, rest, and renewal, and shedding is a part of that cycle. According to the American Academy of Dermatology (AAD), it is normal for a person to lose 50–100 hair per day as part of this process (AAD, 2020).
Where concern arises is when hair fall goes beyond this natural limit—when shedding becomes excessive, persistent, or visibly reduces hair density. That can signal an underlying condition, lifestyle trigger, or environmental factor that needs to be addressed.
In regions like the UAE and across the world, stress, nutrition, climate, medical conditions, and daily habits all play a role in how much hair you shed. Knowing the difference between normal shedding and abnormal loss is the first step to protecting your scalp health and preventing long-term thinning.
The Science of the Hair Growth Cycle
Hair follicles are among the most active organs in the human body. At any given time, about 100,000 follicles on the scalp are in different stages of the growth cycle.
Understanding this cycle helps separate normal shedding from true hair loss disorders.
The Four Phases of Hair Growth
- Anagen (Growth Phase)
- Lasts 2–7 years, depending on genetics, age, and health.
- Around 85–90% of your scalp hair are in this stage right now.
- Each strand grows ~1 cm per month.
- People with longer anagen phases can naturally grow very long hair.
- Catagen (Transition Phase)
- A short 2–3 week stage.
- Hair follicle shrinks and detaches from its blood supply.
- Only 1–2% of hair are in catagen at a time.
- Telogen (Resting Phase)
- Lasts 2–4 months.
- About 10–15% of hair are in this stage.
- The hair is no longer growing but remains anchored to the scalp.
- Exogen (Shedding Phase)
- The final stage where hair is released from the follicle.
- Typically, 50–100 hair per day are shed.
- Immediately followed by a new anagen hair pushing through.
Factors That Influence the Cycle
- Seasonal changes: People shed more during late summer and autumn. A study by Randall et al. (1991) confirmed this pattern in women in the UK (Br J Dermatol).
- Stress: Chronic stress increases cortisol, disrupting the anagen-telogen balance.
- Nutrition: Deficiencies in iron, zinc, Vitamin D, and protein shorten anagen and accelerate shedding.
- Climate (UAE context): High heat, humidity, and desalinated water weaken hair shafts.
- Hormones: Pregnancy, menopause, thyroid imbalance, and PCOS all affect the growth cycle.
What’s Considered Normal Hair Loss?
Most healthy individuals lose between 50 and 100 hair daily. This is normal physiological shedding, not baldness.
1 Everyday Shedding Examples
- Combing or brushing: Strands that were already in exogen get dislodged.
- Washing hair: Water loosens hair about to fall out anyway.
- On pillows or clothes: A few strands appear after friction.
- Seasonal shedding: Noticeable during autumn and spring.
2 Temporary Shedding Conditions
- Postpartum hair fall: After childbirth, hormonal changes cause sudden but temporary shedding.
- Post-illness shedding: Fevers, infections, or major surgeries can trigger telogen effluvium.
- Short-term stress: Exams, deadlines, or trauma may lead to temporary spikes in hair loss.
3 Scientific Reference
The American Academy of Dermatology (AAD) reiterates:
- Losing 50–100 hair daily is healthy.
- Seeing more shedding on wash days does not always mean abnormal loss (AAD, 2020).
The key marker: as long as scalp coverage looks consistent and hair density doesn’t decrease, this shedding is normal.
4 When Hair Loss Becomes a Concern
While shedding 50–100 hair a day is healthy, the alarm bells ring when loss is excessive, prolonged, or visibly affecting density.
4.1 Red Flags to Watch For
- Excessive daily shedding
- If you’re consistently losing well over 100 strands daily.
- Clumps of hair on pillows, shower drains, or brushes.
- Visible thinning
- A widening hair part.
- Reduced ponytail thickness.
- General loss of density across the crown.
- Receding hairline
- Common in androgenetic alopecia (pattern baldness).
- Progressive and usually genetic.
- Patchy bald spots
- Could indicate alopecia areata (autoimmune).
- Appears suddenly and worsens without treatment.
- Sudden unexplained shedding
- Clumps falling rapidly, often after illness, trauma, or medications.
- Scalp symptoms with hair fall
- Itching, redness, dandruff, or burning sensation.
- Indicates underlying scalp conditions such as dermatitis or fungal infections.
Common Causes of Excessive Hair Loss in the UAE
The UAE presents unique challenges for hair health compared to other parts of the world. Factors include extreme climate, water composition, fast-paced lifestyle, and medical conditions.
1. Stress & Fast-Paced Lifestyle
Dubai and Abu Dhabi are bustling hubs, with long working hours, high-performance environments, and frequent travel. Chronic stress increases cortisol, which disrupts the hair growth cycle, forcing follicles into telogen effluvium (resting/shedding phase).
2. Nutritional Deficiencies
Despite access to diverse food, many UAE residents suffer from iron, Vitamin D, B12, and protein deficiencies due to dietary restrictions, fast food reliance, or cultural food habits.
- Iron deficiency is especially critical for women.
- Low ferritin levels (iron stores) are linked with diffuse hair loss.
3. Harsh Climate & Water Quality
UAE summers can reach 50°C with high humidity, stressing both scalp and follicles. To make matters worse, UAE water is mostly desalinated seawater, which:
- Contains chlorine and salts.
- Increases scalp dryness.
- Weakens cuticles, making hair brittle and prone to breakage.
4. Medical Conditions
Several medical issues manifest with hair loss as an early symptom:
- Thyroid disorders (hypothyroidism/hyperthyroidism).
- PCOS in women (linked to androgenic alopecia).
- Diabetes and anemia.
- Autoimmune diseases such as alopecia areata.
5. Styling & Chemical Damage
Many UAE residents use frequent salon treatments such as:
- Keratin straightening.
- Bleaching and coloring.
- Heat styling (blow-drying, flat irons).
While they provide short-term shine, they cause structural hair damage, weakening cuticles and shafts.
Self-Care and Preventive Measures
While some causes of hair loss require medical treatment, lifestyle and preventive care play a big role in maintaining healthy hair.
1. Nutrition for Stronger Hair
Hair is made of keratin protein, and deficiencies in nutrition directly affect its strength and growth.
- Proteins: Eggs, lean meats, lentils, and dairy support keratin production.
- Iron: Prevents telogen effluvium; found in spinach, red meat, dates.
- Vitamin D: Critical for follicle cycling; sources include fatty fish, fortified foods, and supplements.
- Zinc: Supports scalp repair; found in nuts, seeds, and shellfish.
- Omega-3 fatty acids: Reduce scalp inflammation; sources include salmon, walnuts, flaxseeds.
2. Hair & Scalp Care Routine
- Gentle cleansing: Use sulfate-free shampoos; avoid overwashing.
- Oil massages: Coconut or argan oil to boost circulation and hydration.
- Avoid harsh styling: Minimize blow-drying, straightening, and chemical treatments.
- Sun protection: Use hats, scarves, or UV-protectant sprays in the UAE climate.
- Hydration: Drink 2–3 liters of water daily to counter desert dryness.
3. Stress Management
Since stress is a major trigger, lifestyle changes matter:
- Meditation, yoga, or prayer for mindfulness.
- Regular physical activity to regulate hormones.
- 7–8 hours of sleep to support follicle recovery.
