Experimental studies show that the extracts from grape seeds increase the production of cells in the hair follicle. It has also been observed that the grape extracts affect the hair growth cycle in a significant way. They enable the hair strands to move rapidly from telogen (resting) to the anagen (growing) phase. Grape seed extracts stimulate healthy hair growth by defeating the hormone dihydrotestosterone (DHT) that stops the hair follicle growth cycle.

Ginkgo biloba leaf extracts act as good tonic for hair growth. They help to increase and maintain peripheral microcapillary circulation, ultimately improving or maintaining hair growth. The hair growth is stimulated through combined effects on proliferation and apoptosis (cell death) of the cells in the hair follicle.   More detail...
