To promote hair growth and health, it is necessary to stimulate scalp microcirculation (massages, medical procedures, LED therapy) and provide specific nutrients through diet and supplementation.

Stimulating microcirculation is a consistent approach: systematic reviews (e.g., Journal of Cosmetic Dermatology) show that massages and LED light therapy can effectively promote hair density by stimulating follicles. Procedures such as PRP benefit from meta-analyses suggesting an improvement in density, although protocols vary greatly. Regarding nutrition, the link between deficiencies (iron, zinc, B vitamins) and hair loss is firmly established by observational studies. However, the efficacy of supplements (biotin, collagen) remains nuanced: they are primarily beneficial in cases of proven deficiency, but their systematic supplementation in a non-deficient individual lacks robust evidence for accelerated 'growth.' Finally, the use of peels or injections (mesotherapy) falls under advanced cosmetics and clinical care, the success of which depends on the initial cause of the hair fragility.
