Aromatherapy Helps Heal Baldness
Scottish researchers report that aromatherapy
-- an alternative therapy using essential plant oils - can safely
and effectively treat alopecia areata, a form of hair loss that is usually
temporary and related to stress.
In the first scientifically controlled
study of aromatherapy's effect on reversible hair loss, Dr. Isabelle
C. Hay and colleagues at Aberdeen Royal Infirmary, in Scotland, tested
the therapy on 84 patients with alopecia areata.
Roughly half of the patients massaged thyme,
rosemary, lavender, and cedarwood essential oils -- oils that appear
to have hair growth promoting properties -- added to a mixture of ''carrier''
oils into their scalps daily. The other half, the ''control group''
, massaged only the carrier oils -- grapeseed and jojoba oils -- into
their scalps each day.
During the study, neither the researchers
nor the patients knew who was getting the treatment and who was in the
control group. After 7 months of treatment, 44 % of the patients using
the essential oils showed significant improvement, compared with just
15% of those using the carrier oils only.
These findings suggest that at least
one of the essential oils contained a compound or compounds that stimulate
hair growth, the researchers write. "The control group's relative
lack of a response suggests a pharmacoactive property of the topically
applied therapy as opposed to an effect arising from the comforting,
relaxing effect of massage and of the application procedure, which was
the same for both groups," said Hay. Aromatherapy caused no significant
side effects.
In contrast, conventional steroid and
other treatments for alopecia areata, can cause considerable side effects,
they note. "Therefore, this aromatherapy trial, with an improvement
rate of 44% is comparable to and possibly of more benefit than trials
of conventional therapies for alopecia areata," Hay and colleagues
conclude. "Compared with these other treatments, its safety is also
greater.''
