Evidence-based medical treatment is the cornerstone of any effective hair loss protocol. Dr Sin Yong prescribes and oversees a structured stepwise medication protocol — oral and topical therapy alongside nutritional supplementation, exosome topicals and blood test monitoring.

The Philosophy

Topical finasteride is a prescription medicine applied to the scalp for androgenetic hair loss. Like the tablet, it blocks the enzyme that converts testosterone into DHT, but it is designed to act mainly where applied, with lower systemic exposure. Some is still absorbed, so in Singapore it is prescribed after a doctor's assessment and side-effect discussion.

Medical Foundation First

No laser treatment, exosome injection or supplement can compensate for uncontrolled DHT-driven follicle miniaturisation. The medical foundation — addressing the hormonal driver of hair loss with prescription medications — must be established first. Energy treatments and growth factor therapies then build on this foundation to maximise regrowth potential.

The Protocol

A woman in her late thirties by a window, hand resting against her cheek, skin even in tone — Assessment comes before any device or injectable is chosen.

Seven Steps, Evidence-Based

Dr Sin Yong's anti-hair-loss medication protocol is structured as a seven-step programme. Steps are introduced progressively based on diagnosis, response and tolerance. Not every patient requires all seven steps — the protocol is personalised at consultation.

Key facts

Condition: Androgenetic alopecia (AGA) — pattern hair loss in men and women
Underlying mechanism: Dihydrotestosterone (DHT) binds androgen receptors in susceptible follicles, shortening the anagen phase and causing progressive follicular miniaturisation
FDA-approved routes: Two: a topical vasodilator and an oral DHT-pathway therapy
Topical route: A vasodilator, originally developed for an unrelated use. Improves follicular blood perfusion; the hair-growth effect was an incidental discovery
Oral route: Blocks conversion of testosterone to DHT, addressing the driver rather than the symptom
Where therapy alone is not the whole plan, Regenera Activa acts through a third route. Alternative oral route: Inhibits DHT conversion via a broader enzyme pathway. Used in some countries for AGA but not FDA-approved for that indication
Assessment: Oral therapy requires medical assessment, with side-effect profiles discussed before any course begins

The 7-Step Anti-Hair-Loss Medication Protocol

Step 1 — Oral Therapy

Blocks the DHT pathway at the follicle. A well-studied medical treatment for androgenetic alopecia. Prescribed in appropriate candidates after discussion of benefits and risks.

Step 2 — Topical Therapy

A vasodilator that prolongs the anagen (growth) phase of the hair cycle. Available as solution or foam. Effective independently of DHT and can be used in both men and women.

Step 3 — Topical DHT-Pathway Therapy

For patients who wish to reduce systemic exposure, this route delivers active therapy to the scalp with lower systemic absorption than the oral form.

Step 4 — Hormonal Therapy (Selected Cases)

Anti-androgen approach used in selected female patients with androgenetic alopecia or hormonal hair loss where conventional treatments are insufficient.

Step 5 — Nourkin (TricoVerde)

A clinically formulated nutritional supplement containing saw palmetto, biotin, zinc, and key micronutrients shown to support hair follicle health. Used alongside medical treatment for nutritional support.

Step 6 — Derive Serum (Exosome Topical)

An exosome-based scalp topical containing growth factors and signalling molecules. Applied daily to maintain growth factor delivery to follicles between clinic sessions.

Step 7 — Blood Test Monitoring

Dr Sin Yong monitors hair loss treatment response and safety through structured blood testing. Baseline bloods assess for contributing factors (ferritin, iron, thyroid, zinc, hormone levels). Follow-up bloods at 3–6 months monitor treatment response and safety parameters, including liver function where oral therapy is used. Monitoring checks how treatment is being tolerated and allows early detection of contributing nutritional deficiencies that can be corrected.

Topical finasteride in Singapore: who prescribes it and what is discussed

In Singapore, topical finasteride is obtained on a doctor's prescription after assessment, not bought as a cosmetic scalp product. It is the topical DHT-pathway therapy in step 3 of the protocol above, named here for education only.

Assessment comes first because not all thinning is androgenetic. The scalp is examined, and causes such as telogen effluvium, thyroid disease or low iron are considered, which is where the baseline blood tests come in. Finasteride is not for women who are or may become pregnant, and they should avoid handling it.

Side effects are discussed before starting. Scalp irritation can occur where it is applied. Because some of the medicine is absorbed, the effects discussed for the tablet still apply: changes in libido, erection or ejaculation in a minority of men, reported mood changes, and lower PSA readings, which matters for prostate screening. Anyone who notices low mood should stop and seek medical advice.

Controlled trials have compared topical finasteride with placebo and reported smaller falls in blood DHT than with tablets, but lower exposure is not zero. In 2025 the US FDA also alerted the public to side effects reported with compounded topical finasteride products sold online, which is one reason it is prescribed and followed up by a doctor rather than self-sourced.

Minoxidil vs finasteride vs low-level laser for pattern hair loss
Option	How it acts	What it cannot do	How it is obtained	Discussed before starting
Topical minoxidil	Prolongs the growth phase of the hair cycle and enlarges miniaturised follicles where it is applied	Block DHT, or hold its effect once it is stopped	Pharmacy product; a doctor advises on its place in the plan	Scalp irritation, early shedding and unwanted facial hair where it runs
Oral minoxidil (off-label)	Acts on the same hair-cycle mechanism through the bloodstream	Block DHT; it acts on blood vessels throughout the body	Doctor's prescription after a review of blood pressure, heart history and current medicines	Fluid retention, a faster heartbeat, light-headedness and body hair growth
Oral finasteride	Blocks type II 5-alpha reductase, lowering the DHT that drives follicle miniaturisation	Restore follicles already lost; not for women who are or may become pregnant	Doctor's prescription after assessment	Changes in libido, erection or ejaculation in a minority, reported mood changes and lower PSA readings
Topical finasteride	Acts on the same enzyme, applied to the scalp for lower systemic exposure	Avoid absorption entirely; it is a different route, not a different medicine	Doctor's prescription after assessment	Scalp irritation, plus the same systemic precautions as the tablet
Low-level laser (at this practice, H2LT followed by low-level laser)	Red-spectrum light acting on cells in the follicle, used alongside medical therapy	Block DHT or revive a follicle that has already gone	Clinic-based; involves no medication	Its role as an adjunct rather than a standalone treatment

Frequently asked questions

Is topical finasteride safer than oral finasteride?

It is designed to reduce systemic exposure, and trials have reported smaller falls in blood DHT than with tablets, but some of the medicine is still absorbed. The same precautions are therefore considered, including sexual side effects, mood changes and the effect on PSA testing. Which route suits you is a prescribing decision made after assessment.

Frequently Asked Questions — Anti-Hair-Loss Medications

Yes. Oral hair-loss therapy requires prescription in Singapore and must be assessed and prescribed by a licensed doctor. Dr Sin Yong assesses and oversees oral therapy as part of the hair loss protocol.

Oral therapy must be taken continuously to maintain its effect. Stopping typically results in resumption of hair loss within 3–6 months. Most patients who respond well remain on it long-term.

The clinically formulated supplement used contains a proprietary blend including saw palmetto, biotin, zinc, selenium, and other micronutrients formulated to support hair follicle health and reduce shedding.

Yes. Medical therapy alone (oral and/or topical) can effectively slow hair loss and stimulate some regrowth. In-clinic treatments such as laser can be added alongside, but they are not prerequisites.

A baseline panel typically includes: serum ferritin, total iron, TIBC, TSH (thyroid), free T4, zinc, full blood count, liver function, and hormone panel (testosterone, DHT, SHBG) as appropriate. Results guide treatment selection and allow identification of correctable contributing deficiencies.
