Medical Precision — Proven Protocols — Excellence on Harley Street
Hair loss is rarely a single problem with a single solution. The type, pattern, and rate of loss determine which treatments will work — and beginning the right treatment early makes a significant difference to the outcome.
Hair loss affects around half of all men by the age of fifty and up to a third of women at some point in their lives, yet it remains one of the most undertreated medical concerns we see — in part because many patients delay seeking help until significant loss has already occurred, and in part because the sheer volume of ineffective over-the-counter products creates scepticism about what clinical treatment can actually achieve.
At PHP Aesthetic-Wellness, Dr Philippe Hamida-Pisal and Dr Jihyun Byun conduct a thorough hair and scalp assessment before recommending any treatment. The type of hair loss — androgenetic, telogen effluvium, alopecia areata, traction, or nutritional — must be correctly identified, because treatments that are highly effective for one type are ineffective or inappropriate for another. Blood tests, scalp examination, and a detailed clinical history form the foundation of every hair loss consultation at PHP.
“Hair loss has a profound effect on how people feel about themselves, and that is rarely acknowledged with the seriousness it deserves. Our role is to provide an accurate diagnosis, an honest assessment of what treatment can achieve, and a protocol that gives each patient the best realistic chance of meaningful improvement.” PHP Aesthetic-Wellness, 22 Harley Street
Types of Hair Loss
Accurate diagnosis of the hair loss type is the single most important step before any treatment is considered. The patterns below are the most common presentations we assess and treat.
Our Hair Loss Treatments
Every treatment programme at PHP is built around the specific type and stage of hair loss identified at assessment. Most patients benefit from a combination of in-clinic procedures and a prescribed home regimen, working together to stimulate follicular activity and maintain results over time.
PRP — Platelet-Rich Plasma
A concentration of the patient’s own platelets and growth factors — including PDGF, VEGF, and IGF — is injected directly into the scalp at the level of the hair follicle bulb. These growth factors stimulate follicular stem cells, extend the anagen (growth) phase of the hair cycle, improve vascularisation of the scalp, and reduce the DHT-driven miniaturisation of susceptible follicles.
PRP is the most well-evidenced non-surgical hair loss treatment available, with consistent clinical data supporting its use in androgenetic alopecia in both men and women, female pattern hair loss, and telogen effluvium. Results develop progressively over three to six months following each treatment course.
Exosomes
Exosomes are nano-sized extracellular vesicles carrying growth factors, microRNAs, and regenerative signalling molecules that communicate directly with follicular stem cells. Applied to the scalp following microneedling or injection, they stimulate follicular regeneration, modulate the inflammatory micro-environment around the follicle, and regulate the hair cycle at the cellular level — working at a depth of biological action that PRP alone does not reach.
Exosome therapy is increasingly used alongside PRP in androgenetic alopecia and is particularly valuable in alopecia areata and cases where conventional treatments have produced limited response. An emerging and highly promising modality in clinical hair restoration.
Scalp Mesotherapy
A precisely formulated cocktail of follicle-stimulating actives — including biotin, vitamins B5 and B6, zinc, copper peptides, finasteride (where appropriate), and DHT-blocking compounds — is delivered directly into the scalp dermis via microinjections, bypassing the skin barrier and reaching the follicle at the level where it can act most effectively.
Mesotherapy improves scalp microcirculation, delivers nutritional support directly to the follicle, and introduces DHT-inhibiting agents locally — reducing systemic side effects compared to oral finasteride. Particularly effective for female pattern hair loss, telogen effluvium, and as a maintenance treatment between PRP sessions.
Botox® Scalp Injections
Botulinum toxin injected into the scalp musculature reduces the compression of blood vessels supplying the hair follicles — a mechanism linked to DHT-driven miniaturisation in the galea aponeurotica, the fibrous sheet overlying the scalp. By relaxing the galea, scalp Botox® improves blood flow and oxygen delivery to susceptible follicles and may reduce the rate of DHT-mediated miniaturisation.
An emerging treatment with a growing clinical evidence base, particularly for male androgenetic alopecia. Used as part of a combination protocol alongside PRP and mesotherapy rather than as a standalone intervention. Administered as a prescription-only medicine following a full consultation.
Topical Retinoid & Minoxidil
The daily home regimen is inseparable from in-clinic results. Topical minoxidil — available in 2% and 5% concentrations, prescribed to the appropriate strength for each patient — is the most evidence-based topical treatment for androgenetic alopecia and female pattern hair loss, extending the anagen phase and increasing follicular size over a sustained period of use.
Combined with a low-concentration topical retinoid (tretinoin), minoxidil penetration into the scalp is significantly enhanced: tretinoin improves skin permeability at the application site and upregulates the sulfotransferase enzymes responsible for converting minoxidil to its active form. This combination consistently outperforms minoxidil alone in clinical studies. The regimen is prescribed and monitored at PHP; patients are reviewed at three and six months to assess response and adjust the protocol.
What to Expect from Treatment
Hair loss treatments work gradually, and understanding the timeline helps patients stay committed through the period before visible results appear.
Months 1–3
Reduced shedding is typically the first sign of response and often appears before visible regrowth. The scalp environment is being optimised at the follicular level during this period.
Months 3–6
Fine, new growth becomes visible, particularly in areas of thinning. Hair diameter and density begin to improve measurably. Photographic comparison from the initial appointment becomes meaningful at this stage.
Months 6–12
The most significant visible improvement typically occurs in this period as new hairs mature. Maintenance sessions and continued home treatment preserve and consolidate the results achieved.
Your Hair Restoration Journey
Effective hair loss treatment is a programme built on accurate diagnosis, a combined protocol, and consistent monitoring over time.
Hair & Scalp Assessment
Trichoscopic scalp examination, clinical photography, and a targeted blood panel (ferritin, vitamin D, thyroid function, androgen profile where indicated) to identify the type, cause, and stage of hair loss before any treatment is recommended.
Personalised Protocol
A combined in-clinic and home treatment plan tailored to your hair loss type, stage, scalp condition, and lifestyle. In-clinic sessions are sequenced alongside a daily prescription home regimen.
Active Treatment Phase
In-clinic sessions every four to six weeks during the initial course, with photographic progress review at three and six months. The protocol is adjusted as the scalp and hair respond.
Maintenance Programme
Once the initial course is complete, quarterly or twice-yearly maintenance sessions sustain follicular stimulation and prevent the resumption of loss. The home regimen continues throughout.
Related Concerns
Hair loss frequently presents alongside or gives rise to related concerns that are addressed within the same programme:
Scalp Health
Seborrhoeic dermatitis, scalp psoriasis, and dandruff create an inflammatory scalp environment that accelerates hair loss and impairs the response to treatment. Scalp health is assessed and addressed as a priority.
Nutritional Deficiency
Iron, ferritin, vitamin D, and zinc deficiencies are corrected before other treatments are introduced. Supplementation protocols are prescribed alongside in-clinic treatment where deficiencies are identified.
Hair Transplant Referral
Where hair loss is advanced and the patient may benefit from surgical restoration, we provide a clinical summary and support referral to a trusted hair transplant surgeon. Medical treatment before and after surgery significantly improves transplant outcomes.
