Male pattern hair loss (androgenetic alopecia) is a progressive condition driven by DHT sensitivity in genetically predisposed hair follicles. Dr Sin Yong's protocol addresses hair loss at every level — from medical treatments to laser therapy, exosome stimulation and nutritional support — to slow shedding and stimulate regrowth.
Male hair loss treatment in Singapore starts with diagnosis: androgenetic alopecia is a progressive, DHT-driven miniaturisation of genetically susceptible follicles. Trichoscopy and blood tests confirm the pattern and contributing factors, then a plan is built from medical therapy, low-level laser and nutritional support, with hair transplantation discussed where follicles no longer respond.
Androgenetic alopecia affects approximately 50% of men by age 50. The condition is driven by dihydrotestosterone (DHT) — a potent androgen that binds to receptors in genetically susceptible hair follicles, causing them to miniaturise progressively over cycles until they cease producing visible hair. The earlier treatment begins, the more follicles can be preserved.
Dr Sin Yong's male hair loss protocol is multi-modal and evidence-based. Medical treatments (oral or topical therapy) address the hormonal driver at the root cause. The Luminescence Laser, a non-ablative 1540 nm laser, is directed at circulation and the environment around the follicle. Topical exosome preparations applied after laser are proposed to deliver growth-factor signals to follicles. Nutritional support with Nourkin TricoVerde and blood test monitoring complete the protocol.
“A hairline is easier to hold than to reverse — the earlier it is defended, the more survives.”
— Dr Sin Yong
Hair is one of several concerns men raise; the overview of aesthetic treatments for men sets out the others and where each is explained.
For the other types of hair loss, see every hair guide.
H2LT, Dr Sin Yong's low-level laser protocol for the scalp, is usually used alongside medical management.
The Luminescence Laser, a non-ablative 1540 nm laser, is used in some hair regrowth plans.
Trichoscopy and clinical assessment to determine the pattern, stage and rate of loss. Blood tests to identify contributing factors (iron, ferritin, thyroid, zinc, hormones).
Oral DHT-pathway therapy to reduce DHT, and/or topical vasodilator therapy to prolong the anagen phase. These are the first-line medical therapies for androgenetic alopecia.
The Luminescence Laser is a non-ablative 1540 nm laser, not low-level laser therapy. On the scalp it is directed at circulation and the environment around the follicle, after the cause of hair loss is diagnosed. Recommended as first-line alongside medical treatment.
Exosome-rich preparations applied to the scalp after laser are proposed to deliver growth factors, cytokines and signalling molecules that stimulate follicle activity and prolong the anagen phase.
Nutritional supplementation with Nourkin TricoVerde — a clinically formulated supplement containing saw palmetto, biotin, zinc and other hair-supportive nutrients.
Exosome-based topical scalp serum applied daily between clinic sessions to maintain growth factor delivery to follicles.
Male hair loss treatment is chosen by stage, not by what is on offer. This table describes the stages in words, what the examination shows at each, the options usually discussed and what is deliberately not offered. Trichoscopy and blood tests at the first visit settle which row a scalp belongs to.
A hairline is defended while it is still there; once a zone is shiny there is nothing left for a laser to stimulate.— Dr Sin Yong
| Stage in words | What the examination shows | Options usually discussed | What is not offered | Page |
|---|---|---|---|---|
| Early: hairline or crown just starting to thin | Finer hairs at the temples or vertex; parting still covers; miniaturisation visible on trichoscopy | Medical therapy for the DHT driver, low-level laser, nutritional support and blood test monitoring | A transplant into a scalp that still has its own hair to defend | Receding hairline |
| Established: visible widening or a bare patch forming | Mixed calibre hairs; scalp shows through under light; the pattern is clear | The full protocol, with Regenera Activa micrografts considered on a treated scalp | Stimulation sold as a substitute for treating the androgen driver | Regenera Activa |
| Later stage: smooth, shiny zones with hair at the back and sides | No follicle openings in the bare zone; donor hair intact | Medical therapy to hold what remains, and an honest transplant conversation with referral | Laser or micrografts aimed at a zone with nothing left to stimulate | Hair transplant, assessed honestly |
| Diffuse or sudden shedding at any age | Hair coming out across the whole scalp; a positive pull test; often a trigger in the history | Investigation of the cause first: illness, medicines, thyroid, iron and stress | A pattern-loss protocol for a shedding problem that has not been diagnosed | Sudden hair shedding |
Dr Sin Yong performs trichoscopy and reviews your hair loss pattern, family history and any previous treatments. Blood tests are requested at this stage.
A personalised protocol is designed based on your assessment findings. The combination and sequence of medical, laser and injectable treatments is mapped.
Medical prescriptions are provided. Luminescence Laser sessions begin. Topical exosome applications are scheduled. Topical support is initiated.
Hair loss protocols require time. A formal review at 3 months assesses response and allows protocol adjustment. Photography documents progress.
Men with advanced loss and long-dormant follicles, or with patchy or scarring hair loss, tend to respond poorly to this protocol, which is the wrong tool until the type is confirmed.
Expected effects depend on the treatment. Topical products can irritate the scalp, and shedding can appear to increase early on before it settles. Oral anti-androgen therapy carries a risk-benefit profile that is discussed at consultation, including sexual side effects reported in a minority of users, and mood changes are also reported. Laser sessions are generally well tolerated, with mild warmth the main sensation. Allergic reactions and infection are uncommon but possible. No treatment can promise regrowth, and response varies between individuals, so progress is reviewed with photographs at planned visits.
The fee for male hair loss treatment depends on the pattern and stage of loss, which parts of the protocol are chosen (prescribed medicines, Luminescence Laser, nutritional support, topical scalp care), how the plan is paced between visits, and whether other in-clinic scalp treatment is added. Trichoscopy and blood tests form part of the assessment. A written quote is given at consultation after assessment, and the consultation also decides whether treatment is advised at all.
How quotes work at this practice: how we quote.
Most male hair loss is androgenetic, driven by DHT acting on genetically susceptible follicles, though stress and nutrition can add to shedding.
Medical and laser treatment work on follicles that are still active, which is why earlier assessment keeps more options open.

Oral hair-loss therapy is FDA-approved for male pattern hair loss and has an established long-term safety profile. Sexual side effects are reported in a small minority of users and typically resolve on stopping the medication. Dr Sin Yong discusses the risk-benefit profile at consultation.
Hair loss protocols require patience. Hair cycles are slow, so progress is reviewed at intervals from around 3 months, with a fuller assessment at 12 months. Response varies between individuals.
Not necessarily. Dr Sin Yong designs a protocol appropriate to your degree of loss, response to previous treatments and goals. Some patients begin with medical treatment and Luminescence Laser; others require the full multi-modal protocol.
In later-stage androgenetic alopecia where follicles have been dormant for many years, medical and energy treatments may not achieve regrowth. Hair restoration (hair transplantation) may then be considered. Dr Sin Yong assesses candidacy and discusses realistic expectations at consultation.
The fee depends on the pattern and stage of loss, which parts of the protocol are chosen, how the plan is paced and whether other scalp treatment is added. Trichoscopy and blood tests are part of the assessment. A written quote is given at consultation after assessment, and the consultation decides whether treatment is advised at all. Figures are not quoted in advance.
It tends to suit men with early to moderate androgenetic thinning who still have active follicles and will commit to a long-term protocol with reviews. It is a poorer fit where follicles have been dormant for many years, where the cause is not confirmed, or where someone wants quick regrowth. Assessment shows which group you are in.
No duration is promised. Androgenetic alopecia is progressive, so benefit from medical therapy generally depends on continuing it, while laser and topical support are adjuncts. Longevity is influenced by genetics, age, how early treatment starts, adherence and contributing factors such as nutrition. Review timing is set at consultation and adjusted according to response.
Treatment is usually long term and needs regular reviews. Oral therapy can carry side effects that are discussed beforehand, and shedding may appear to increase early on. Response varies, and treatment cannot regrow follicles already lost. A multi-part protocol adds visits and cost, and in later-stage loss a transplant opinion may be more suitable.
