Finding more hair on your pillow, in the shower or while styling your hair can be worrying,but you're not alone.
Hair loss affects millions of men worldwide and becomes increasingly common with age. The good news is that most causes of hair loss are well understood, and many can be treated successfully when identified early.
The first step isn't choosing a product, it's understanding why your hair is thinning.
What is considered normal hair fall?
Losing 50–100 hairs a day is completely normal.
Instead of counting individual hairs, pay attention to changes such as:
-
A receding hairline.
-
Thinning at the temples.
-
More scalp becoming visible at the crown.
-
Your hairstyle looking less dense than it used to.
-
Shedding that continues for several months.
-
Patchy areas of hair loss.
The pattern of hair loss often tells us more than the number of hairs you lose each day.
What causes hair loss in men?
Hair loss isn't one condition-it has many possible causes.
The most common include:
Male Pattern Hair Loss
This is the most common type of hair loss in men.
It usually begins with a receding hairline, thinning at the temples or gradual hair loss over the crown.
It's caused by a combination of genetics and sensitivity of the hair follicles to dihydrotestosterone (DHT). Over time, DHT causes susceptible follicles to gradually shrink, producing thinner, shorter hairs until they eventually stop producing visible hair.
Stress & Illness
Major physical or emotional stress can temporarily push a large number of hairs into the shedding phase.
This is called telogen effluvium.
The shedding usually begins 2–3 months after the triggering event and often improves within six to nine months once the body recovers.
Common triggers include:
-
High fever or severe illness
-
Surgery
-
Rapid weight loss
-
Crash dieting
-
Significant emotional stress
Nutritional Deficiencies
Hair is often one of the first tissues to reflect nutritional deficiencies.
Common deficiencies include:
-
Iron (Ferritin)
-
Vitamin D
-
Vitamin B12
-
Zinc
-
Inadequate protein intake
Medical Conditions
Certain medical conditions can contribute to hair loss, including:
-
Thyroid disorders
-
Autoimmune conditions such as Alopecia Areata
-
Certain medications
-
Chemotherapy
-
Severe scalp infections or inflammatory scalp conditions
What blood tests should I ask for?
If your hair loss has continued for more than 2–3 months, speak to your doctor about whether investigations are appropriate.
Common tests include:
-
Complete Blood Count (CBC)
-
Serum Ferritin
-
Vitamin D
-
Vitamin B12
-
Thyroid Profile (TSH, Free T3, Free T4)
Depending on your symptoms and medical history, your doctor may recommend additional tests.
What treatments actually work?
The best treatment depends entirely on what's causing the hair loss.
1. Minoxidil
Minoxidil is one of the most widely studied topical treatments for male pattern hair loss and is available without a prescription in many countries.
It works by prolonging the hair growth phase and stimulating hair follicles. Results usually take 4–6 months of consistent use, and treatment needs to be continued to maintain improvement.
2. Finasteride (Prescription Only)
Finasteride is an oral prescription medication that reduces the production of DHT-the hormone primarily responsible for male pattern hair loss.
By lowering DHT levels, it helps slow ongoing hair loss and may promote regrowth in many men.
Because it is a prescription medicine with potential side effects, it should only be taken under the guidance of a qualified doctor.
3. A Good Hair Growth Serum
For men with early thinning, a well-formulated daily hair serum can be an excellent addition to a hair care routine.
Look for formulations containing clinically studied ingredients such as:
-
Peptides (e.g. Biotinoyl Tripeptide-1, Copper Tripeptide-1)
-
Redensyl, Procapil, Anagain.
-
Caffeine
-
Rosemary extract
-
Biotin
A lightweight, non-greasy formulation makes daily use easier and consistency is key.
4. GFC & PRP
Growth Factor Concentrate (GFC) and Platelet-Rich Plasma (PRP) are in-clinic procedures performed by dermatologists.
They use growth factors to support the hair follicle environment and may benefit selected patients, particularly those with early male pattern hair loss.
These treatments are often most effective when combined with medical therapy rather than used alone.
5. Treat the Underlying Cause
Not all hair loss requires the same treatment.
If the cause is:
-
Iron or vitamin deficiency - correcting the deficiency is often the most important step.
-
Thyroid disease - treating the thyroid disorder often improves hair shedding.
-
Stress-related shedding - hair often recovers once the underlying trigger resolves.
-
Scalp disease - treating inflammation or infection may help restore healthy hair growth.
Treating the cause-not just the symptom-is what leads to the best long-term results.
When should I see a dermatologist?
Arrange an evaluation if you notice:
-
Hair loss lasting longer than three months.
-
A receding hairline or thinning crown.
-
Patchy bald spots.
-
Hair loss with scalp redness, pain or itching.
-
Rapid or sudden hair shedding.
Early treatment usually offers the best chance of preserving healthy hair.
The Bottom Line
Hair loss in men is extremely common-but it isn't something you should simply accept.
Whether it's caused by genetics, nutritional deficiencies, temporary stress or an underlying medical condition, identifying the underlying cause is the first step towards effective treatment.
The earlier hair loss is recognised, the more options are available to slow progression and preserve healthy hair.
If you're noticing persistent thinning, don't guess. Get the diagnosis first, then choose the treatment that matches the cause.
