Saw Palmetto Extract Boosts Hair Growth in Adults with Thinning Hair
Taking a saw palmetto supplement increased hair growth by 283% in adults concerned about hair thinning.
Summary
In plain language
In a recent study, researchers found that adults experiencing hair thinning showed significant improvements in hair growth after taking a saw palmetto extract supplement. Over six months, participants who took the supplement experienced a 283% increase in hair growth compared to those who took a placebo. This study suggests that saw palmetto, a natural extract, might be a helpful option for those looking to improve hair density and health. This finding is particularly meaningful for seniors who may be concerned about hair thinning. Discussing this option with a healthcare provider could be worthwhile for those interested in natural remedies.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study involved 60 adults aged 25 to 65 years, with a focus on those experiencing hair thinning. Participants were divided into two groups: one received a daily saw palmetto supplement, and the other a placebo. The trial lasted 180 days, with hair growth assessed through detailed scalp measurements.
The study found a significant increase in hair growth for the supplement group, with a notable 283% improvement over the placebo group.
Participants taking saw palmetto showed increased hair density and health, especially in the posterior scalp area.
While promising, the study's small size and specific population mean more research is needed to confirm these findings.
For seniors interested in natural hair loss treatments, discussing this supplement with a healthcare provider could be beneficial.
