Hair Exosome Before and After | Part Line Density and Crown Regrowth

The goal was denser hair at the crown and less visible scalp through her central part — without surgery.

Close-range scalp assessment showed diffuse follicular miniaturization at the crown with scalp clearly visible through the hair at the part line. Hair shaft caliber was reduced throughout the treatment zone, with shorter, finer hairs indicating active miniaturization rather than terminal shedding. The pattern — central and crown-predominant with retained frontal hairline — is consistent with female androgenetic alopecia. Follicular units remained present and viable, indicating capacity to respond to exosome growth factor signaling.

Dr. Sabeen Munib administered exosome therapy via scalp injection targeting the crown and part line zone, delivering extracellular vesicles with concentrated growth factors, signaling proteins, and cytokines to the follicular microenvironment. In the after image, scalp visibility through the part line is substantially reduced, hair coverage across the crown reads as denser, and finer new hairs are visible filling in along the part. Exosomes restore intercellular communication in a follicular environment disrupted by miniaturization — the result is follicular reactivation rather than surface-level stimulation.
