Why Is My Hair Thinning? The Most Advanced Hair Restoration Treatments Available in London in 2026

Hair thinning is one of the most common concerns patients raise at Skin Lab Medispa, and one of the most under-addressed. Most patients have been noticing gradual changes for months or years before they finally seek clinical advice. They have tried thickening shampoos, scalp serums, biotin supplements and every product the internet recommends. Nothing has made a meaningful difference. That is because the cause of hair thinning is biological, not cosmetic and it requires a biological solution.

In 2026 three genuinely advanced regenerative treatments are available at Skin Lab Medispa across our Marylebone, Old Street and Monument clinics that address hair thinning at its biological root. Purasomes exosome hair therapy, PRP hair restoration, and polynucleotide scalp treatment. Each one works differently. Each one is right for different patients and different presentations. And for the first time all three are available at our City of London Monument clinic, two minutes from Bank and Monument stations making them accessible to the City and Square Mile professional community for the first time.

This article covers why hair thins, what each of the three treatments does at a biological level, and which one is most likely to produce the result you are looking for.

Why Is My Hair Thinning? The Real Causes

Hair thinning has multiple causes, and understanding which cause is driving your specific presentation is the first step toward effective treatment. The most common causes our clinical team see in London patients in 2026 are as follows.

Androgenetic alopecia - pattern hair thinning driven by genetic sensitivity to dihydrotestosterone is the most common cause of gradual hair thinning in both men and women. In men it typically presents as a receding hairline and thinning at the crown. In women it presents as diffuse thinning across the top of the scalp with the parting widening gradually over time. It is progressive without intervention, meaning it does not resolve on its own and will continue to worsen without treatment.

Telogen effluvium - a form of temporary diffuse shedding triggered by physiological stress is increasingly common among City and professional London patients. Sustained work pressure, poor sleep, nutritional deficiencies, illness, or significant life events can push a large proportion of hair follicles into the resting phase simultaneously, causing noticeable shedding two to three months after the triggering event. The hair typically regrows but without treatment the recovery is slow and the hair that returns can be finer and weaker than before.

Postpartum hair loss - a specific form of telogen effluvium triggered by the hormonal shift after childbirth affects a significant proportion of new mothers, typically beginning two to four months after delivery. The hair loss can be significant and distressing. Regenerative treatments that stimulate follicle activity and improve scalp health are particularly effective in this context because they work with the body's natural recovery process rather than against it.

Nutritional deficiency and stress-related thinning low ferritin, low vitamin D, thyroid imbalance, and sustained cortisol elevation from chronic stress all affect the hair growth cycle. These causes are addressed through a combination of nutritional support and regenerative scalp treatment. Our clinical team will assess relevant blood markers at consultation where appropriate.

The cause of your hair thinning determines which treatment is most appropriate, which is why every hair restoration appointment at Skin Lab Medispa begins with a thorough clinical assessment before any treatment is recommended.

The Three Most Advanced Hair Restoration Treatments in London in 2026

Purasomes Exosome Hair Therapy - HSC50 Hair and Scalp Complex

Purasomes exosome therapy is the most advanced regenerative hair restoration treatment available in London in 2026 and one of the most significant developments in non-surgical hair restoration in the last decade.

Exosomes are nano-sized extracellular vesicles produced by stem cells that act as biological messengers, carrying growth factors, proteins, and genetic information between cells to coordinate regenerative processes throughout the body. The Purasomes HSC50 Hair and Scalp Complex contains 20 billion high-purity exosomes alongside 20 specific growth factors formulated specifically to target hair follicles and the scalp microenvironment.

When injected directly into the scalp the Purasomes HSC50 signals dermal papilla cells, the specialised cells at the base of each hair follicle that control the hair growth cycle to reset and reactivate. Dormant follicles are stimulated back into the active growth phase. Miniaturised follicles, those producing progressively finer, shorter hairs as androgenetic alopecia progresses receive signals to strengthen and produce thicker, more robust hairs. Scalp inflammation, which accelerates follicle miniaturisation, is reduced.

The result is genuinely transformative for patients who are suitable candidates. Hair density improves. Shedding reduces. The quality and calibre of existing hair improves. New hair growth becomes visible in areas where follicles are dormant but not yet irreversibly lost.

Purasomes HSC50 is CE marked with 14 registered patents and has been manufactured by the Dermoaroma Group in Italy to pharmaceutical-grade standards. It is reconstituted fresh immediately before every treatment, ensuring maximum biological activity at the point of injection.

First improvements in scalp health and shedding reduction are typically noticeable within four to eight weeks of the first session. Visible improvement in hair density develops progressively over a course of three sessions spaced four weeks apart.

Purasomes exosome hair therapy from £350 per session. Course of three from £950. Available at Skin Lab Medispa Marylebone, Old Street and Monument.

PRP Hair Restoration

Platelet-rich plasma hair restoration uses your own blood, a small sample taken from the arm during your appointment, concentrated in a centrifuge to produce a plasma solution containing a significantly elevated concentration of your own platelets and the growth factors they contain. This PRP is then injected directly into the scalp at the follicle level.

The growth factors in PRP - including PDGF, VEGF, EGF, IGF-1 and TGF-beta stimulate blood supply to the follicles, extend the active growth phase of the hair cycle, and signal follicle cells to produce more robust hair. Because PRP uses your own biology there is no risk of allergic reaction or rejection. The treatment has one of the strongest safety profiles of any injectable treatment available.

PRP hair restoration is particularly effective for patients in the early to moderate stages of androgenetic alopecia, for postpartum hair loss, and for patients experiencing stress or nutritional deficiency-related shedding. It works best as a course, three sessions spaced four to six weeks apart with maintenance sessions every six to twelve months to sustain the result.

PRP hair restoration from £300 per session. Course of three from £795. Available at all three Skin Lab Medispa clinics.

The Combination That Produces the Most Comprehensive Result

Purasomes exosome therapy combined with PRP in a single appointment produces a synergistic result that neither treatment achieves alone. PRP delivers your own growth factors to stimulate the immediate follicular environment. Purasomes adds 20 billion pharmaceutical-grade exosomes with 20 specific growth factors that work at a deeper cellular level to reset follicle biology. Together they address both the immediate growth stimulus and the longer-term biological reprogramming of the follicle.

This combination protocol is what we recommend for patients with moderate to significant hair thinning who want the most comprehensive non-surgical hair restoration result available in London. The combined appointment takes approximately 60 minutes and is available same-week at all three Skin Lab Medispa clinics.

Purasomes plus PRP combination from £580. Course of three from £1,600.

Polynucleotide Scalp Treatment

Polynucleotides - the same purified DNA fragment bio-stimulators used in our skin regeneration treatments are also highly effective when applied to the scalp for hair quality improvement and early-stage thinning. Polynucleotide scalp treatment signals the scalp skin cells to repair, regenerate and produce new collagen and growth factors from within, improving scalp health, reducing inflammation, and creating a more favourable biological environment for hair growth.

Polynucleotide scalp treatment is the most appropriate starting point for patients with very early stage thinning, scalp health concerns, or patients who want to maintain and improve hair quality rather than address significant loss. It is also an excellent adjunct treatment alongside Purasomes or PRP for patients who want to address both follicle health and scalp quality simultaneously.

Polynucleotide scalp treatment from £250 per session. Available at all three Skin Lab Medispa clinics.
