So, there's this one study that's been making rounds in the hair loss community like the latest gossip at a high school reunion. Published in the journal "Skinmed" in 2015, researchers put rosemary oil in the ring with 2% minoxidil, which is the FDA-approved go-to for treating androgenic alopecia. Over the course of six months, they observed that both groups had significant hair growth. Hold the phone, right? Well, not so fast.
While this sounds like a breakthrough, it's crucial to remember that this was a single study, relatively small in scale, with 50 participants split into two groups. That's like trying to decide if a movie is good based on a handful of reviews. What's more, the study didn't solely focus on androgenic alopecia, which, remember, is our main contender here.
Now, the reason rosemary oil isn't the end-all for androgenic alopecia is rooted in the condition's mechanism. This type of hair loss is due to the sensitivity of hair follicles to dihydrotestosterone (DHT), a byproduct of testosterone. DHT shrinks the hair follicles, leading to thinner hair and, eventually, no hair. While rosemary oil may improve blood circulation and has anti-inflammatory properties, there's no direct evidence that it can counteract the effects of DHT on the follicle.
In the grand scheme of scientific research, we're still waiting on the large-scale, long-term studies that can give us a clear verdict on rosemary oil for androgenic alopecia. Until then, while it might boost hair health in general (which is great for your remaining locks), it's not a certified warrior against the specific hormonal onslaught of androgenic alopecia.
