TLDR Tomato extract can promote hair growth and prevent hair loss without irritating the skin.

A decade ago, a study was conducted to evaluate the potential hair growth-promoting activity of Lycopersicon esculentum extracts. The extracts were applied on the dorsal skin of C57BL/6 mice once a day for 4 weeks. At week 4, the Lycopersicon esculentum extracts showed hair growth-promoting potential similar to that of 3% minoxidil, a common hair growth treatment. The study also found a significant increase in the expression of growth factors such as vascular endothelial growth factor (VEGF), keratinocyte growth factor, and insulin-like growth factor-1 (IGF-1) in the group treated with the extracts. Histological examination showed that the induction of the anagen stage of hair follicles was faster in the group treated with the extracts than in the control group. No skin irritation was observed after exposure for 24 or 72 hours. The study concluded that Lycopersicon esculentum extracts promote hair growth and could be used in hair loss treatments without causing skin irritation at moderate doses.
