Thuja Orientalis Tested Results to Address Hair Loss

There are numerous potential uses for the extracts and essential oils of the Thuja Orientalis plant, many of which may help support the health of the scalp along with potential for promoting hair growth. Following is a brief summary of the studies performed on Thuja Orientalis and its reputed benefits to hair growth.

The ‘Hot Water’ T. Orientalis Topical Test

One of the most significant studies on Thuja Orientalis was carried out on lab mice. The test mice were shaved and then separated into three groups.

The first group would be given a daily topical ‘hot water’ solution of T. Orientalis extracts, the second was administered a daily topical ‘1% minodoxil’ solution and the rest of the mice formed the control group.

After 14 days the hair growth of each group of test mice was carefully measured, averaged and analyzed with impressive results. The mice being given the T. Orientalis treatment had produced significantly more hair growth than either the group being given a 1% minodoxil solution or the control group.

After 17 days, the T. Orientalis group had regained their full coat of hair, while the control group had only about 50% regrowth (See Fig. 1)

Further analyses of the results of this test showed that T. Orientalis improved hair growth in test subjects by inducing the anagen growth phase from the telogen phase.

The anagen phase is the stage where hair follicle is actually growing hair, while the telogen represents the period of follicle rest. Many hair follicles can be in perfect working conditions; the T. Orientalis treatment has been found to rouse resting follicles, recommissioning active hair production.

Furthermore, researchers documenting the study were quick to notice an increase in hair follicle size and numbers per square inch in the T. Orientalis group. Immunohistochemical analyses also detected earlier induction of the essential heir raising proteins, Shh and β-catenin in hair follicles stimulated by regular T. Orientalis treatment.

The final conclusions reported by these researchers clearly indicate that T. Orientalis can effectively promote hair growth by stimulating resting follicles into their hair production stage or anagen stage. This means that T. Orientalis can be considered an all-natural agent to promote hair growth.
