Angelica Sinensis (Dong-Quai), a precious herbal medicine is used as one of the pivotal active ingredients in Ha'Labo treatments. Its primary function is that it promotes oxygen release into the blood stream that will spread easily to scalp tissue cells. 
The Angelica extract has been proven not only to prevent hair loss but improves the scalp’s blood circulation, supplying essential nutrients for hair growth and inhibiting DHT, an androgen infamously known as a “hair follicle killer”, known to cause hair loss but shrinking the hair follicles and shortens the lifespan and growth of hair.
