Regenerative hair and skin treatments: what the evidence really supports

Équipe médicale Nuance Clinic

Regenerative aesthetics is the most over-promised field in the industry. This guide separates what PRP and growth-factor treatments genuinely achieve for hair thinning and skin quality from marketing claims, and explains the medical work-up that should come first.

En bref

  • Works on living but miniaturised follicles, not on scarred or lost ones.
  • A blood work-up should precede any hair-loss treatment.
  • Measure results with trichoscopic photographs at three and six months.
  • Insist on transparency about which product is being injected.

De quoi s’agit-il

  • The term covers several distinct approaches: autologous platelet-rich plasma, growth-factor concentrates and cell-derived conditioned media. They share a mechanism — signalling molecules that push resting cells into an active, repairing state.
  • For hair, the target is the follicle in the resting phase; for skin, the target is the fibroblast and the dermal matrix.

À qui cela s’adresse

  • Early to moderate androgenetic hair thinning, telogen effluvium after illness or stress
  • Skin with early laxity, dullness and poor texture
  • Patients who want a biological rather than volumising approach
  • Not suitable in active scalp infection, blood disorders, some cancers, or pregnancy

Produits utilisés

Autologous PRP prepared in a closed CE-approved system, and CE-approved growth-factor products

Déroulé du traitement

  • Assessment: for hair, a trichoscopic examination and blood tests where indicated (ferritin, thyroid, vitamin D).
  • Preparation of the product in sterile conditions.
  • Micro-injections across the scalp or face, with topical anaesthesia or cooling.

Sécurité

  • Autologous treatments carry no rejection risk but must be prepared in a closed, sterile system.
  • We do not offer unlicensed 'stem cell' injections; we explain clearly which product is being used and what evidence supports it.

Avant le rendez-vous

Well hydrated on the day; avoid anti-inflammatory medication for 3 days if medically allowed; wash hair before scalp treatment.

Soins après le traitement

No hair products or washing for 12–24 hours after scalp treatment; no sauna, pool or gym for 24 hours.

Résultats et durée

  • Reduced shedding within 4–8 weeks; visible density change from month 3.
  • Skin texture and firmness improve gradually across the course.
  • Underlying causes — iron deficiency, thyroid disease, hormonal factors — must be treated in parallel.

Effets indésirables et risques possibles

Scalp tenderness, mild swelling, bruising, temporary headache; infection is rare with sterile technique.

Suivi

Trichoscopic photographs at baseline and month 3–6 so change is measured, not guessed.

Questions sur ce traitement

Will it regrow hair I have already lost?

It improves follicles that are still alive but miniaturised. Completely lost follicles do not return with injections; a transplant is the option there.

Is it painful?

Scalp injections are uncomfortable rather than painful, and we use cooling and topical anaesthesia.

How many sessions before I see change?

Reduced shedding at 4–8 weeks, visible density at three months, assessed with comparison photographs.
