A Hair-Raising Study: Can the daily application of CBD oil cause significant hair regrowth? New research says it can

Posted by

US researches enrolled 28 men and 7 women in a hair regrowth study, all of whom were suffering from hair loss.

Each participant was asked to apply 3-4 mg of hemp-derived CBD oil to their scalp once a day for 6 months. Hair quantity & length was measured before and after.

Result: “On average, [there was] a statistically significant 93.5% increase in … hair,” – essentially doubling whatever hair there was to begin with – and men did “slightly better” than women.

Interestingly, the paper suggests two ways to improve on the findings.

First, since hair regrowth is “dose dependent,” the implication is you could increase the amount of CBD that you use and/or use it for a longer period of time.

Second, the results were comparable to the two medications typically prescribed to restore hair loss. And because CBD works through “novel mechanisms different from [these drugs], it can be used in conjunction with [them] and would be expected to have synergistic effects.”

The authors believe CBD works because it enhances the growth phase of the hair follicle cycle, thereby causing new hair follicle growth and hair shaft elongation.

They also report that all subjects had some regrowth and that there were no adverse effects.
