The effects of an association of nutrients on human follicular dermal papilla: an in vitro study

Abstract

INTRODUCTION: The skin aging process includes a functional decline of the scalp’s structures, with progressive atrophy of the dermis and follicular dermal papillae, which are crucial to the nutrition and metabolism of the hair follicle. These phenomena are directly related to a poor quality of the hair shaft.
OBJECTIVE: To evaluate the influence of a combination of nutrients on the keratinogenesis in the follicular dermal papilla.
METHODS: Cell cultures of human dermal papillae were incubated with a combination of A, C, D, E and B-complex vitamins, in addition to trace elements and keratin amino acids during 72 hours, in three different concentrations. These cultures were compared to an untreated control-culture. The papilla’s fibroblasts cell proliferation rate was determined after 72 hours.
RESULTS: The diverse concentrations evaluated promoted significant increase in cell proliferation as compared to the control group, however there was no significant difference between the concentrations studied.
CONCLUSION: The studied association of nutrients was capable to significantly act on the proliferation of cells in the human hair follicle’s dermal papilla, restoring more favorable conditions for the synthesis of the hair shaft. These findings demonstrate the presence of a significant potential in the approach strategy various causes of alopecia, including alopecia related to aging (senescent).
