摘要：
背景：
方法： 对于此可行性研究，人口由年龄之间的男性组成在过去的12个月内经历了20年和60年的s，并且诊断为AGA。在Fitzpatrick皮肤类型秤上，他们还具有3、3a，3 V，4、4a或5的Norwood-Hamilton分类，以及I型I，II，III或IV的皮肤。 This two-arm randomized, parallel group study design employed stratifying randomization to balance treatment assignment within three investigational centers with at least 2 subjects enrolled in each Fitzpatrick skin type.
RESULTS: A statistically significant positive trend in hair growth was observed from this pilot study, to evaluate the efficacy of the novel cold X5用于治疗雄性雄激素脱发的发射手装置。从重复的方差分析中，随着时间的流逝，平均头发计数的差异在统计学上是显着的（F = 7.70； P值<0.0001）。随后的每个时间点平均头发计数的线性回归为进行的，事后分析发现，随着时间的推移，头发生长的趋势越来越多，这具有统计学意义（p值<0.0001），估计斜率为1.406。 Increased hair counts from the baseline to the end of the 26-week period were found to be strongly significant (p-value = 0.0003).
CONCLUSION: Albeit, sham device failure and resultant missing data from the control group, the positive trend hair growth, was observed due to the chronic use of X5hairlaser device. This positive benefit while in full agreement with other low laser hair devices requires intensive further investigation.
