Hair loss is one of the most searched hair concerns in South Africa — and one of the most misunderstood. The internet is full of miracle claims, while the products that genuinely help are often overlooked because they work slowly and quietly. This guide explains why hair thins, which ingredients have real evidence behind them, and how to build a routine that gives your follicles the best possible chance.
First, Understand the Hair Cycle
Every hair on your head cycles through three phases: anagen (active growth, 2–7 years), catagen (transition, a few weeks) and telogen (rest and shedding, around 3 months). Losing 50–100 hairs a day is completely normal — those are telogen hairs making way for new growth. Hair loss becomes a concern when more follicles than usual shift into the resting phase, or when follicles shrink and produce progressively finer, shorter hairs.
This matters because it sets realistic expectations: any product that supports the hair cycle needs at least one full cycle — 3 to 6 months — before you can fairly judge results.
The Main Causes of Hair Loss
Androgenetic alopecia (pattern hair loss): The most common cause in both men and women. Follicles sensitive to DHT (dihydrotestosterone) gradually miniaturise — producing thinner, shorter hairs until they stop producing altogether. In men it typically shows as a receding hairline and crown thinning; in women, as diffuse thinning along the part line.
Telogen effluvium: A temporary shedding triggered by a shock to the system — severe stress, illness, surgery, crash dieting or childbirth. Shedding usually appears 2–3 months after the trigger and resolves once the cause passes, though good scalp care speeds the recovery.
Nutritional deficiency: Iron, zinc, biotin and protein deficiencies all show up in the hair first — the body deprioritises hair when resources are scarce. This is one of the few causes where supplements make a measurable difference.
Traction alopecia: Hair loss caused by sustained pulling — tight braids, weaves, extensions and slick ponytails are the usual culprits. It is common, preventable and reversible if caught early, but permanent if the tension continues for years. If your hairline is receding where your braids pull, the first treatment is looser styling.
Hair fall vs breakage: Not all "hair loss" is loss at the root. If you find short snapped pieces rather than full-length hairs with a small white bulb, you are dealing with breakage — a damage problem, not a follicle problem — and strengthening ranges like Kérastase Genesis are the right tool.
Ingredients With Real Evidence
Stemoxydine: Developed by L'Oréal's research labs, Stemoxydine works by mimicking a low-oxygen environment at the follicle, signalling dormant follicles to re-enter the growth phase. It is the key active in Kérastase Densifique, with clinical results showing improved hair density over 90 days of daily use.
Aminexil: Targets the rigidification of collagen around the follicle root that anchors hairs poorly and contributes to hair fall. Found in Kérastase Genesis Sérum Anti-Chute and L'Oréal Professionnel's Aminexil serums.
Nanoxidil: DS Laboratories' alternative to Minoxidil with a lower molecular weight for better absorption — the headline active in the DS Laboratories Spectral range, alongside caffeine and ketoconazole in the Revita system.
Caffeine and ketoconazole: Caffeine stimulates follicle activity at the scalp level; ketoconazole reduces scalp inflammation and has a mild anti-DHT effect. Both feature in DS Laboratories Revita — the most clinically intensive shampoo system we stock.
Biotin, collagen, zinc and iron: The supplement side of the equation. They will not regrow hair on their own, but where a deficiency exists, correcting it removes a genuine handbrake. Quick Grow and Newtrino are South African ranges formulated specifically for this, and our biotin collection gathers every biotin-based option in one place.
The Complete 5-Step Routine
1. Hair loss shampoo: Cleanses sebum and DHT build-up from the follicle opening and creates the scalp environment growth needs. Nioxin System shampoos, DS Laboratories Revita and Kérastase Genesis Bain Hydra-Fortifiant are the strongest options.
2. Lightweight conditioner: Mid-lengths and ends only — never weigh down the roots you are trying to lift.
3. Leave-on scalp treatment: The single most important step. A serum applied directly to the scalp after washing delivers actives where they matter — Nioxin Scalp Treatment, DS Spectral.DNC-N or Kérastase Genesis Sérum Anti-Chute.
4. Supplements: Address the nutritional side, especially if your diet is restricted or blood tests show low iron or zinc.
5. Scalp massage: Four to five minutes daily with fingertips or a massage tool increases blood flow to the follicles and improves serum absorption. Free, and genuinely supported by research.

Which System Fits Your Situation?
Early or general thinning: Nioxin — the world's most widely used professional thinning system, available in six variants matched to hair type and degree of thinning.
Advanced thinning or no response to gentler products: DS Laboratories Revita and Spectral — the most pharmaceutical-adjacent option available without prescription.
Hair fall from breakage and weakness: Kérastase Genesis — strengthens the fibre and reduces fall caused by snapping rather than shedding.
Lost density and body: Kérastase Densifique — Stemoxydine-led density restoration over 90 days.
Nutritional support: Quick Grow or Newtrino supplements alongside any of the above.
When to See a Professional
Sudden patchy loss, loss accompanied by scalp pain or scaling, or shedding that has not slowed after six months deserves a GP or dermatologist visit — some causes (thyroid conditions, autoimmune alopecia areata, scarring alopecias) need medical treatment, and no cosmetic product replaces that.
For everything else, start with a conversation in the chair. Our stylists across 24 Partners Hair salons in Cape Town see thinning hair every day and can tell you honestly whether you are dealing with breakage, shedding or miniaturisation — and which system fits.
Frequently Asked Questions
How long before hair growth products show results? A minimum of 3 months, realistically 6. Hair grows roughly 1.25cm per month and the cycle takes months to respond. Photograph your part line or hairline monthly — day-to-day mirror checks will deceive you.
Can shampoo alone stop hair loss? Shampoo is the supporting act, not the headline. It optimises the scalp environment, but leave-on serums deliver actives with far longer contact time. Use both.
Will hair grow back after stopping the products? If the underlying cause persists — DHT sensitivity in particular — gains gradually reverse once treatment stops. Pattern hair loss management is ongoing, like skincare.
Is treatment different for men and women? The products are largely the same; the patterns differ. Most systems we stock — Nioxin, Genesis, Revita — are used by both. Nioxin and Newtrino offer variants formulated separately for men and women.
Are these products safe with braids, weaves and chemically treated hair? Yes — scalp serums apply directly to the scalp between rows. If you wear tight protective styles, pair any growth routine with looser tension at the hairline to avoid working against yourself.
