There are many causes of hair loss. In addition to hereditary hair loss, hair loss caused by environmental and habitual factors should also be considered. Causes of hair loss include external environmental stressors, such as particulate matters, and stress hormones like cortisol. 

Groccoli is an extract of broccoli sprouts. It can promote the proliferation of hair cells, inhibit dandruff bacteria, and relieve inflammation. Groccoli also alleviates hair loss by suppressing the expression of hair loss-inducing genes which are induced by cortisol and by restoring the expression of growth factors decreased by cortisol.
