Scalp Microinfusion: A Novel Drug Delivery Technique for Hair Loss Treatment.

Scalp microinfusion is a promising novel drug delivery technique for hair loss treatment. We discuss the MMP® technique and review its possible use in alopecias. MMP® technique provides a small amount of drugs delivered homogeneously into the skin combined with micro-needling and can, therefore, provide optimal delivery. However, literature on this technique is limited to a few case reports despite its wide use in some countries. Further studies are needed to standardize protocols.
