Eucalyptus oil for hair can encourage circulation and be used as an antifungal agent. The use of this type of oil on the hair is often popular among individuals with dry, damaged scalps who may also be suffering from hair loss. The organic extract is believed by many to be able to control dandruff, mild forms of psoriasis, and encourage the growth of new hair. In small amounts, it may be added to a daily hair care regimen to maintain healthy shine and a clear scalp. It is typically available for purchase as an undiluted oil from local apothecaries and through Internet ordering.

Daily applications of eucalyptus oil for hair health can increase blood circulation to the scalp and promote hair shine. As blood is encouraged to circulate throughout this area, hair follicle growth is stimulated. The individual shafts of hair, as a result, become stronger and more elastic as nutrients flow to their roots.

The increased circulation when using eucalyptus oil for hair can also relieve symptoms associated with mild psoriasis and dry scalp. These conditions, in which the scalp becomes red, dry, itchy and begins to flake, may be caused by overly dry skin or a sudden overproduction in hair oils which clogs follicles. A healthy amount of blood flow to the scalp can help eliminate the build up of bacteria in hair follicles internally, as well as naturally moisturizing and soothing the irritated skin surrounding the follicles.

Eucalyptus oil is also a natural antiseptic and antifungal agent. When massaged gently into the scalp as part of an undiluted mask treatment, it works to eliminate bacterial and fungal growth in the upper layers of the scalp and hair follicles. This healing property makes eucalyptus oil an effective treatment against some mild cases of scalp pimples. The naturally strong and soothing woodsy fragrance of this oil can help to mask the sometimes unpleasant odors associated with infected hair follicles as the scalp gradually heals.

This natural plant extract typically ranges in color from clear to light yellow. It can be added to any type of shampoo used daily, or mixed in an undiluted form with other organic ingredients intended for use in a hair mask. It is often recommended that eucalyptus oil for hair mask treatments be applied exclusively on damaged or tired hair, and that it should be left to soak into hair overnight or for several hours. Other popular ingredients for this type of homemade remedy may include honey, olive oil, and coconut oil.
