Dandruff is a condition of the scalp that is more a source of embarrassment than a sign of serious illness. It's a case of dead skin from the scalp falling off in "flakes." Since the flakes are usually white, they are especially noticeable when you are wearing dark clothing. There are over-the-counter and prescription shampoos to treat dandruff, as well as treatments featuring rosemary oil. Although these treatments may not be medically proven to cure dandruff, they may be something worth discussing with your physician.
History
Rosemary oil is one of the more popular oils, as it has been touted--though not studied enough to be proven--to help reduce pain, boost memory and grow hair. The rosemary plant, which is part of the mint family, has been used as an herb in cooking, but it is the oil that comes from the leaves which has been used medicinally. As far back as the 16th century, the physician Paracelsus used rosemary in medical treatments for the heart, brain and liver, according to the website Organic Facts.
Mechanism
Dr. Nicole Sundene, a naturopathic doctor who writes about the use of herbs for Wellsphere, notes that dandruff usually worsens as we grow older. She also counts rosemary as an herb to treat dandruff because it has anti-fungal properties. Sundene says that it works similarly to the prescription shampoos because it kills the yeast while calming the scalp itching.
Formula
There are a number of ways to use rosemary as a treatment for dandruff. You can purchase shampoos with rosemary oil or mix it into your own shampoo. Sundene believes it is also effective as a scalp spray. She suggests making your own with aloe vera juice, calendula, lavender and tea tree oil, in addition to the rosemary. According to Sundene, the formula can be used twice a day to help with the dandruff, and Organic Facts agrees that tea tree oil works well with rosemary to alleviate dry scalps.
Interesting Facts
Rosemary extract is already being used in many everyday lotions and shampoos. According to Organic Facts, the consistent use of rosemary oil in shampoos stimulates follicles, which can increase hair growth and strength. Rosemary also may deter premature hair loss and graying hair. The plant is beneficial to skin the same way it helps with dandruff, by relieving dryness and providing nourishment.
Warning
Do not use rosemary--or any essential oil--on your scalp without diluting it with water. While Sundene believes that rosemary can help dandruff, she warns that burning or additional flaking can occur. If side effects occur or symptoms do not improve, rinse the rosemary out of your hair immediately, and consult a health care professional. Do not use rosemary oil on babies.
