Non-Surgical Hair Restoration

What Is Non-Surgical Hair Restoration?

Hair loss is more common — and more treatable — than many patients realize. Whether you are experiencing gradual thinning at the crown, a receding hairline, postpartum shedding, or diffuse volume loss across the scalp, non-surgical approaches can meaningfully slow progression, stimulate dormant follicles, and restore density without surgery or downtime.

As a head and neck surgeon and otolaryngologist, Dr. Kieu evaluates hair loss from a medical foundation — understanding the type, pattern, and cause of your loss before recommending any treatment. A comprehensive consultation guides a personalized plan that may combine regenerative biologics, prescription medications, and topical therapies.

Conditions We Treat

• Androgenetic alopecia — male and female pattern hair loss
• Diffuse thinning — generalized volume loss without complete follicle loss
• Telogen effluvium — postpartum or stress-related shedding
• Traction alopecia — thinning related to hairstyling tension
• Early alopecia areata — in select appropriate cases
• Post-transplant maintenance — supporting and extending surgical hair restoration results
• Hormonal hair loss — thinning related to thyroid, androgen, or estrogen fluctuations

Platelet-Rich Plasma (PRP) Therapy

PRP is the most established biologic treatment in hair restoration. A small blood draw is processed in a centrifuge to concentrate your own platelets — which are dense with growth factors including PDGF, VEGF, and TGF-β. These are then injected directly into the scalp at the level of the follicle to stimulate the anagen (growth) phase and reduce follicular miniaturization.

Most patients undergo an initial series of three sessions spaced four weeks apart, followed by maintenance treatments every four to six months. Visible improvement in density and reduced shedding is typically apparent between three and six months into treatment.

Exosome Therapy

Exosomes are nanoscale extracellular vesicles that carry signaling proteins, growth factors, and RNA between cells. When delivered into the scalp, they communicate directly with follicular stem cells to promote repair, reduce inflammation, and stimulate regeneration — often offering more potent cellular signaling than PRP alone.

Exosome therapy is particularly well-suited for patients with more advanced thinning, those who have not achieved optimal results with PRP, or patients seeking to amplify an existing treatment protocol. It is commonly combined with PRP in the same session.

PRP vs. Exosomes: Which Is Right for You?

Both treatments work through different — and often complementary — mechanisms. PRP uses your body's own growth factors; exosomes deliver a highly concentrated signaling payload from an external biologic source. Many patients benefit most from a combined approach tailored to their degree of loss and treatment history. This is determined at your consultation.

Topical Medications

Topical agents deliver active ingredients directly to the scalp, maximizing local concentration while minimizing systemic exposure. They are a cornerstone of most hair restoration protocols — whether used independently or alongside biologic therapies.

Oral Medications

Systemic medications address the hormonal and inflammatory drivers of follicle miniaturization at their source. All oral prescriptions are made in the context of a complete health history, and ongoing monitoring is provided as clinically appropriate.

Finasteride

A 5-alpha reductase inhibitor that blocks the conversion of testosterone to dihydrotestosterone (DHT) — the primary androgen responsible for androgenetic alopecia in men. Well-studied with decades of clinical data. Full effect is typically seen at 12 months.

Dutasteride

A more potent 5-ARI that inhibits both type I and type II 5-alpha reductase isoenzymes, resulting in a greater reduction of DHT than finasteride. Used off-label for patients with more advanced androgenetic alopecia or those who have not responded fully to finasteride.

Spironolactone

An anti-androgen commonly prescribed for women with hormonal pattern hair loss. Reduces androgenic activity at the follicle level. Not appropriate for women who are pregnant or planning pregnancy. Periodic lab monitoring is standard.

Low-Dose Oral Minoxidil

Low-dose oral minoxidil (0.625–2.5 mg daily) is an emerging option with growing evidence for both men and women who do not tolerate or respond sufficiently to topical application. It is prescribed selectively based on cardiovascular history and overall health profile.

Nutraceuticals & Supplements

Nutritional deficiencies — including low ferritin, vitamin D, zinc, and B vitamins — can significantly contribute to hair shedding. Dr. Kieu may order targeted labs and recommend evidence-supported supplementation as part of your treatment plan.

The Treatment Experience

Biologic treatments (PRP and exosomes) are performed in-office and are typically completed in 45–75 minutes. A topical anesthetic is applied prior to injections to minimize discomfort. Most patients describe mild pressure or brief sensitivity during the procedure. There is no downtime, and normal activities can be resumed immediately after.

A follow-up appointment is scheduled at six weeks to assess early response and refine your protocol as needed. Progress is tracked with standardized scalp photography at each visit.

How Often Should You Be Treated?

The standard initial protocol for PRP is three sessions spaced four weeks apart. Following the initial series, most patients continue with maintenance treatments every four to six months to sustain results. Exosome therapy may be performed once annually or in combination with PRP sessions depending on your response.

Topical and oral medications are ongoing therapies — their benefit is cumulative and depends on consistent use. Many patients find that combining biologic treatments with daily medical therapy produces the most durable outcomes over time.

Ideal Candidates

• Adults experiencing early-to-moderate androgenetic alopecia
• Patients with diffuse thinning and intact follicles
• Those with postpartum, stress-related, or nutritional hair loss
• Patients seeking to delay or avoid surgical hair restoration
• Post-transplant patients maintaining surgical results
• Good general health; not pregnant or breastfeeding
