Hair loss (alopecia) affects appearance and self-esteem. Causes include androgenetic alopecia (genetic pattern baldness), autoimmune alopecia areata, nutritional deficiencies, or stress-induced shedding. Treatment depends on cause and aims to stabilise hair loss, regrow hair, or manage cosmetically.
For androgenetic alopecia, minoxidil (topical, 2% or 5% solution, or 5% foam) stimulates hair growth and slows loss; benefits are visible after 3–6 months and require ongoing use. Finasteride (1 mg daily, oral) blocks DHT conversion and is effective in men for slowing or reversing loss; it is not approved for women. Biotin, iron, and B-vitamin supplementation help if deficiency exists. Low-level laser therapy (LLLT) devices are FDA-cleared and show modest benefit with consistent use. For alopecia areata, topical corticosteroids, injectable intralesional corticosteroids, or oral corticosteroids may arrest loss and promote regrowth, though results are variable. Hair transplantation (follicular unit transplantation or extraction, FUT/FUE) is surgical, effective for permanent hair replacement, but requires donor supply and is expensive.
Scalp massage and topical herbal treatments (saw palmetto, rosemary, onion juice) are used traditionally with limited evidence. Platelet-rich plasma (PRP) injections into the scalp are increasingly popular; early data suggests benefit for androgenetic alopecia, though large trials are pending. Low-level laser and LED light therapy devices proliferate in the market; evidence is modest and variable by device. Some practitioners use microneedling with serums to enhance penetration, though rigorous trials are lacking. Nutritional approaches—iron, zinc, protein—support hair health if deficiency is present.
Stem-cell therapies for hair loss are emerging, particularly for androgenetic alopecia. Adipose-derived or bone-marrow-derived mesenchymal stem cells, injected into the scalp or used to create a cellular scaffold, may stimulate hair-follicle proliferation and reduce inflammation. Several clinical trials are underway, with early results promising. These approaches remain investigational and are not yet standard care in most markets. Candidacy depends on hair-loss severity, hair-follicle status, and access to research sites. Learn more at stem-cell options for hair restoration and candidacy evaluation.
| Option | Type | Evidence | Indicative cost | Invasiveness | Recovery |
|---|---|---|---|---|---|
| Minoxidil (topical) | Standard | Strong | €30–60/month | Low | Ongoing; 3–6 months to see benefit |
| Finasteride (oral, men only) | Standard | Strong | €10–30/month | Low | Ongoing; 3–6 months benefit |
| Intralesional corticosteroids (alopecia areata) | Standard | Moderate | €100–200 per injection | Medium | Few days; repeated as needed |
| Hair transplantation (FUT/FUE) | Standard | Strong | €3,000–15,000 | High | 2–3 weeks initial; 6–12 months full result |
| Low-level laser therapy (LLLT) | Standard | Moderate | €50–300 (device) + use time | Low | None; ongoing use needed |
| PRP scalp injections | Alternative | Moderate | €400–1,000 per session | Medium | Few days; series of sessions |
| Microneedling with topical serums | Alternative | Limited | €100–300 per session | Medium | 3–7 days mild erythema |
| Stem-cell scalp therapy | Regenerative | Investigational | €3,000–10,000 | Medium | Few days; ongoing research |
Both require at least 3–6 months of consistent use before visible improvement. Minoxidil works by stimulating growth; finasteride by slowing loss. Stopping either reverses benefit within months. Patience and adherence are essential; many see modest improvement rather than dramatic regrowth.
Yes—transplanted follicles from the back of the scalp are genetically resistant to androgenetic alopecia and remain permanent. However, surrounding non-transplanted hair may continue to thin if you have pattern baldness. Transplantation works best in early-to-moderate loss when sufficient donor hair is available.
PRP is popular and early trials suggest benefit for androgenetic alopecia, particularly when combined with minoxidil or microneedling. Evidence is still accumulating; results vary by treatment protocol, clinic, and individual. It is not yet standard care but is gaining adoption as an adjunct.
