Hair loss questions, answered plainly

These are the questions people actually ask us about hair loss and its treatment in South Africa. The answers are general and educational. Your own situation should be assessed by an HPCSA-registered doctor, who can confirm the cause and whether treatment is right for you.

The basics

Is hair loss reversible?

It depends on the cause. Most permanent-looking thinning is androgenetic alopecia (male or female pattern), driven by sensitivity to a hormone called DHT. You cannot cure it, but proven treatments can slow it down and, in many people, thicken and partly regrow hair while they keep using them. Other types, like telogen effluvium after stress, illness, childbirth or a crash diet, often recover on their own once the trigger passes. Thyroid problems and iron deficiency can also be corrected. That is why getting the cause right matters before you spend money on anything.

How long until I see results?

Hair grows slowly, so patience is part of the deal. With finasteride or minoxidil you should give it 3 to 6 months before judging, and closer to 12 months to see the full effect. Taking clear photos every couple of months in the same light helps, because day-to-day change is too small to notice in the mirror.

Are the results permanent?

No. Treatment for pattern hair loss is maintenance-dependent. If you stop, the DHT sensitivity is still there, and within about 6 to 12 months you tend to lose the hair the treatment was holding onto, plus whatever you would have lost anyway. It is worth deciding upfront whether you are happy to treat this as an ongoing thing, a bit like managing blood pressure.

Treatments and side effects

What are the main treatments?

The evidence-based options are oral finasteride (for men), topical minoxidil (men and women), and for some women spironolactone, which is prescribed off-label. Finasteride lowers DHT. Minoxidil improves blood flow to the follicle and prolongs the growth phase. Many people use finasteride and minoxidil together because they work in different ways. We compare the two on our finasteride vs minoxidil page.

What are the side effects?

Most people tolerate these medicines well, but no medicine is free of risk. Finasteride can cause sexual side effects such as reduced libido in a small minority of men, and these usually settle after stopping. Minoxidil can cause scalp irritation, and some people notice a little extra facial or body hair with heavier use. A registered doctor will go through the risks with you and check that nothing in your history makes treatment unsuitable. Tell the doctor about any mood changes.

Does finasteride affect fertility?

For most men at the standard low dose used for hair loss, finasteride does not meaningfully affect fertility. It can slightly reduce semen volume in some men, which usually reverses on stopping. If you are actively trying to conceive and have concerns, raise it during your consultation so the doctor can advise you and, if needed, suggest an alternative.

Why is my hair shedding more after starting minoxidil?

Early shedding on minoxidil is common and, oddly, a sign the medicine is working. It pushes resting follicles into a new growth cycle, so weaker hairs are let go before stronger ones come through. It usually shows up in the first few weeks and settles within a couple of months. If shedding is heavy or lasts longer than that, check in with the doctor.

For women

Can women use these treatments?

Yes, but not all of them. Topical minoxidil is used by women and is well studied for female pattern hair loss. Spironolactone is prescribed off-label for some women. Finasteride is generally not used in women who are or may become pregnant, because lowering DHT can harm a developing male foetus. Female hair loss also has its own common causes, so assessment matters. There is more on our for women page.

Prescriptions, cost and online treatment

Do I need a prescription in South Africa?

Oral finasteride and spironolactone are prescription-only medicines in South Africa and must be prescribed by a registered doctor. Some minoxidil products are available over the counter, but doing it properly, with the right diagnosis and dose, still starts with a proper assessment. Our medical partner handles the consultation and prescription for you.

Roughly how much does treatment cost?

Costs vary by product and by whether you use one medicine or a combination, but ongoing pattern-hair-loss treatment in South Africa generally lands somewhere in the low hundreds of Rand per month. Generic finasteride is inexpensive. Because you keep taking it to hold results, think of it as a monthly cost rather than a once-off. Current pricing is shown when you start a consultation.

Is online hair-loss treatment legit and safe in South Africa?

Yes, when it is done through a properly registered service. Consultations and prescriptions here are handled by Online Doctor SA, South Africa's largest telehealth service, using HPCSA-registered doctors and SAPC-registered pharmacy partners. You complete a medical questionnaire, a doctor reviews it, and medicine is dispensed and delivered only if it is appropriate for you. Be wary of any site that ships prescription medicine with no doctor involved. Our how it works page walks through the process.

Can I just buy finasteride online without a consultation?

You should not, and a legitimate SA service will not let you. Finasteride is prescription-only for good reason. The consultation exists to confirm the cause of your hair loss, check your medical history, and make sure the medicine is safe for you specifically.

What if my hair loss is not the usual pattern type?

Then treatment for pattern hair loss may not help, and could delay sorting out the real issue. Sudden or patchy loss, loss with scalp pain, redness or scarring, or thinning alongside symptoms like fatigue can point to something else, such as an iron or thyroid problem, a medication effect, or traction alopecia from tight hairstyles. Our causes page covers these, and the doctor will flag anything that needs a different route.

Ready to find out what is going on?

The quickest way to get a clear answer is a short online consultation. A registered doctor reviews your history and recommends a plan, or refers you on if something else is going on.
