Every day, we normally shed up to 125 hairs. We are familiar, however, with the comic character who runs around and pulls out his hair while enduring a stressful situation. You may be amazed to learn there really is a connection between stress and hair loss.
Stress restricts the flow of chi (energy) and blood to the scalp. The severe stress of major surgery or illness can cause hair to stop growing and shift into a resting phase. Two or three months later, the resting hairs suddenly begin to fall out. Stress can also trigger a type of hair loss in which white blood cells attack the hair follicles and halt hair growth.
As we get older, both men and women experience some hair loss. It is a normal part of the aging process and often runs in families. Characterized by a receding hair line and baldness on the top of the head in men, hair loss in women takes the form of a general thinning of the hair.
Both men and women produce the hormone testosterone. Because of interaction with an enzyme, testosterone can be converted to DHT, which shrinks hair follicles. This causes the membranes in the scalp to thicken, become inelastic and restrict blood flow. When the follicles atrophy, hair falls out and usually is not replaced. Since men produce more testosterone than women, they experience more hair loss. Areas of the scalp that are completely bald no longer have live follicles. Areas with shorter, fuzzy, fine hairs still have live follicles that may respond to Chinese herbal remedies.
In Chinese medicine, healthy hair depends on an abundant flow of chi and blood to the scalp. Blood is produced through the digestive process, and blood deficiency can be caused by dietary or digestive insufficiencies. Hair loss is also linked to kidney deficiency syndrome.
Chinese herbs have been effective in promoting hair growth by balancing hormones, restoring kidney energy and directing nourishing blood to the scalp. The main Chinese herbal remedy is he shou wu, which strengthens the hair, increases blood production, and may reverse graying. Herbs such as saw palmetto and licorice root help block the formation of DHT.
