According to a new study, baldness may soon be reversible.
Using pairs of identical twins, the study assessed the efficacy of dutasteride, an enzyme inhibitor, as a means of reducing hair loss and encouraging new growth. Dutasteride was found to be an effective means of combating baldness.
Dutasteride is commonly prescribed for benign prostatic hyperplasia, making it similar to finasteride which is sold under the brand name Propecia.
In the study, one twin was given 0.5 mg/day of the drug, the other received a placebo. Results were monitored over the course of a year. After both six and twelve-month intervals, hair loss was found to not only have been halted in the twins using dutasteride, but hair growth was actively improved.
The rate of growth increased between the 6 and 12-month evaluations, while hair loss continued steadily in the placebo group. Male pattern hair loss affects as many as 50 percent of men by the age of fifty.
