Safflower extract has been shown in at least one study to significantly increase the growth factors VEGF and keratinocyte, both of which play a key role in increasing hair growth.
Topically applied pea sprout extract has been shown in one study to increase the growth factor FGF7, which has been shown in research to increase the growth phase of hair follicles.

Sandalore is a perfume chemical designed to smell like Sandalwood. Amazingly though, researchers have discovered that the chemical binds to receptors in the scalp, causing the hair growth phase length to increase and an increase in IGF-1 secretion, leading to increased hair growth.
