TL;DR:
- Hair loss has many causes — identifying yours before investing in products is the single most important step
- The most common causes: genetics and DHT, stress, iron deficiency, thyroid dysfunction, and hormonal changes
- Products support follicle health and reduce shedding. They can't override unaddressed medical causes
- Most hair loss responds to a combination of addressing the root cause, a consistent scalp routine, and patience over 3 to 12 months
- A scalp consultation at Partners Hair is a practical, accessible first step
Hair loss is one of the most Googled health concerns in South Africa — and one of the most confusing, because the same symptom (shedding or thinning) can have completely different causes that need completely different approaches. This guide exists to give you clarity: understand what type of hair loss you're dealing with, what's driving it, and what actually works.

Step 1: Identify Your Type of Hair Loss
Before buying anything or changing your routine, identify what type of hair loss you're dealing with. The pattern tells you almost everything.
Receding hairline or thinning crown (gradual over years)
Most likely androgenetic alopecia — genetic pattern hair loss driven by sensitivity to DHT. The most common type in South Africa. Responds to minoxidil, DHT-blocking products, and in some cases medical treatment.
Sudden, diffuse shedding across the whole scalp
Often telogen effluvium — triggered by stress, illness, nutritional deficiency, or hormonal changes. Usually temporary once the trigger is resolved. Classic delay: shedding happens 2 to 3 months after the event.
Smooth, round bald patches appearing suddenly
Likely alopecia areata — an autoimmune condition. Requires medical assessment and treatment. Standard hair loss products are not effective for this type.
Hair loss concentrated at the temples and hairline
Could be traction alopecia (from tight hairstyles) or frontal fibrosing alopecia. Early intervention is critical — especially for scarring types.
Dry, brittle hair breaking mid-shaft
This is usually breakage, not true hair loss. The hair is snapping from the shaft rather than shedding from the follicle. Bond repair and moisture treatments address this.
"Identifying the type is the conversation I have first with every client," says Judy, head trainer. "The approach for telogen effluvium is completely different from androgenetic alopecia. Using the wrong routine won't cause harm, but it wastes time and money. Start with the right question."
The Main Causes of Hair Loss in South Africa
Genetics and Hormones (Androgenetic Alopecia)
The most common cause of hair loss in men and women. Sensitivity to DHT (dihydrotestosterone) gradually miniaturises hair follicles, producing finer and shorter hair until growth stops. Women typically experience diffuse thinning at the crown and widening part rather than the receding hairline seen in men. Responds to minoxidil (topical), DHT-blocking shampoos (ketoconazole, saw palmetto), and in some cases medical treatment like finasteride or anti-androgenic contraceptives. Requires ongoing management rather than a cure.
Telogen Effluvium (Stress and Shock-Related Shedding)
The second most common type. Physical or emotional stress pushes large numbers of follicles into the resting phase simultaneously — causing diffuse shedding 2 to 3 months later. Triggers include illness (including COVID-19 recovery), surgery, childbirth, grief, job loss, crash dieting, and nutritional deficiencies. Usually resolves within 3 to 6 months once the trigger is addressed. The follicle is not damaged — full regrowth is typical.
Iron Deficiency
One of the most common and most missed causes of hair loss in women. Low ferritin (stored iron) deprives follicles of oxygen, pushing them into the resting phase. Ask for a ferritin test specifically — not just a standard blood count. Target: 70 to 80 micrograms per litre. Shedding slows 2 to 3 months after ferritin levels recover. Full regrowth takes 6 to 12 months.
Thyroid Dysfunction
Both underactive (hypothyroidism) and overactive (hyperthyroidism) thyroid can disrupt the hair growth cycle. Often presents with other symptoms (fatigue, weight changes, temperature sensitivity) but hair can be the first sign. Requires a full thyroid panel: TSH, Free T3, Free T4, and antibodies. Treated medically; hair recovers as thyroid levels stabilise.
Postpartum and Hormonal Hair Loss
After childbirth, sudden oestrogen drop causes the hair that was "on hold" during pregnancy to shed simultaneously. Typically peaks at 3 to 4 months postpartum and resolves by 12 months. Hormonal contraception (particularly high-androgenic progestogens) can trigger or accelerate genetic hair loss in susceptible women. Stopping the pill can also cause temporary shedding.
Alopecia Areata
An autoimmune condition causing patchy hair loss. The immune system attacks follicles, creating smooth, round bald patches. The follicle remains alive — spontaneous regrowth is possible. Requires medical treatment (corticosteroids, JAK inhibitors). Standard hair loss products are not effective for this type.
Traction Alopecia
Hair loss caused by repeated pulling from tight hairstyles. Develops slowly over months or years. Earliest signs: soreness, small bumps, and short broken hairs at the hairline. Early-stage is reversible — late-stage, where follicles have scarred, is permanent. Treatment: immediately modify or stop the offending hairstyle.
What Works — and What Doesn't
What works: Identifying and addressing the underlying cause — consistently using a scalp-supportive shampoo and targeted serum — correcting nutritional deficiencies — minoxidil for androgenetic alopecia and telogen effluvium — medical treatment for alopecia areata and scarring conditions — protecting existing hair from mechanical damage and heat.
What doesn't: Using the wrong product for the wrong type of hair loss — expecting results in less than 3 months — shampoo alone without a targeted serum — supplementing with nutrients you're not deficient in — continuing to cause damage while trying to repair.
"Products are support tools," says Lewis. "They work best when you've identified the cause and addressed it. A hair loss shampoo and serum on top of an unresolved iron deficiency is working against the tide. Fix the deficiency first — then the products have a chance."
The Complete Hair Loss Routine
Wash days (2 to 4 times per week): Scalp-supportive shampoo (look for caffeine, ketoconazole, or zinc pyrithione) — leave on 1 to 2 minutes before rinsing — conditioner on mid-lengths and ends only — towel dry — apply scalp serum.
Daily: Targeted scalp serum (minoxidil, rosemary oil, or peptides) applied to dry scalp — supplements if deficiency confirmed by blood test.
Ongoing: Gentle handling, protective styling, heat protection, monthly progress photos, and reassessment at 6 months.
When to See a Professional
See your GP: for blood tests (ferritin, thyroid, vitamin D, zinc), and if you have other symptoms alongside hair loss. See a trichologist: if shedding has continued for 3 or more months without a clear cause, if you have patchy loss, receding hairline, or scalp symptoms alongside shedding, or if a 6-month product routine hasn't improved things. See a dermatologist: for suspected alopecia areata, scarring alopecia, or if prescription treatment is needed. Start with a salon scalp consultation: if you're not sure where to begin — our team can assess your pattern, point you in the right direction, and recommend appropriate products.
Frequently Asked Questions
What is the main cause of hair loss in South Africa?
Genetics (androgenetic alopecia) is the most common cause, followed by telogen effluvium (stress and nutritional triggers) and iron deficiency. Identifying your specific cause determines the right approach.
Can hair grow back after thinning?
It depends on the cause. Telogen effluvium and iron deficiency hair loss typically recover fully once the trigger is resolved. Androgenetic alopecia requires ongoing management. Alopecia areata can regrow but is unpredictable. Scarring alopecia and very advanced follicle damage have limited recovery potential.
Do hair loss products really work?
Yes — when matched to the right type of hair loss. Products are most effective when the underlying cause is also being addressed. They support scalp health, reduce shedding, and stimulate regrowth — but they can't override an unresolved medical or nutritional cause.
How long does it take to see results?
Most people start noticing reduced shedding within 2 to 3 months and visible regrowth within 4 to 6 months of a consistent routine. Full results are typically assessed at 12 months. Hair grows approximately 1cm per month.
What's the most important first step?
Get a blood test. Checking ferritin, thyroid function, vitamin D, and zinc before investing in products saves time and money and ensures your routine is matched to what your hair actually needs.
