大家好，我也是一名脱发患者，最近这几天里，到处可以见到有关据棕榈的帖子与新闻！我相信，许多朋友们谈到据棕榈的时候，心里一定非常想问一个问题，那就是“到底治疗脱发有没有效” 事实上，在我们对于据棕榈不多的情况下，是很难真正获知其到底有么有效的。正确客观的分析据棕榈，才能够真正的了解据棕榈。下面是本人总结的一些关于据棕榈的文章，希望对大家有所帮助
据棕榈的介绍：
锯棕榈籽粹取（锯棕榈浆果提取/固相萃取），或称棕榈树果实（塞雷诺阿草），学名叫做Permixon，百年前就被印地安人用来改善摄护腺分面的问题，欧美也广泛应用在摄护腺症状的改善与预防上。所以，他并非是所谓的新药，且对于雄性秃朋友来说，也是早已熟知的成份了，只是现在再经由媒体的介绍，也让更多人能够去了解他的用途了。
外用据棕榈：
美国品牌的Revivogen（中译。立发健），Hairgenesis（中译。发源），Crinagen（中译。快来俊），欧系品牌的护蕾（Ducray），植物（发朵），这些产品的特性，效果优劣，价格高低也都具有差异性的。此外，锯棕榈萃取多半只是养发液其中多种成分之一而已，并非是单一成分的产品。这类外用产品如果应用得宜，可以用来弥补口服药在抑制DHT的效果的不足，或是用来搭配落建生发水，可以在外用的治疗方式上，获得更好的预期效果。但要注意的是，固相萃取本来就是一种油性物质，必须要能够找出适合自己生活作息的使用方式，才能兼顾长期使用的稳定性。另外，固相萃取的副作用机率同样较低，可能会有头皮过敏的可能（红肿痛痒）。
外用锯棕榈的效果在实证上，确实是比口服锯棕榈更加完整可信的，尽量以外用为首选，但外用产品毕竟是比口服麻烦一些，要能够耐心使用才有意义。总之，我们都可以跟自己的需求来决定要口服还是外用啰。
内服据棕榈：
如果柔沛或波斯卡让人产生恼人的副作用时，口服锯棕榈可用来在替代药物上，也可以用来做初期的预防，毕竟没有人会先吃药来预防雄性秃的发生，或者是在治疗初期，不想这么早服用口服药。但市面上的这些产品，通常会多添加其他可以用来阻断双氢睾酮的成分，如非洲刺梨（臀果木），绿茶中的儿茶素（儿茶素）等，价格也会比单一成分的锯棕榈来的高一些，且来源地多是以美国为主。至于副作用部份，口服锯棕榈的副作用机率极少，在一个315人的研究中发现（四Authie和j的Cauquil的Permixon的日常实践中药理学与临床疗效的多中心研究;。。5（56）:3 - 13，1987），98％的服用者并没有副作用产生，而最常见的副作用症状多半为反胃或是轻微头痛，口服锯棕榈为脂溶性，最好在进餐时服用，大概一到两个小时就会被吸受。
下面大家非常关注的，到底据棕榈的治疗脱发有么有效果呢？
锯棕榈萃取物，已经被证实可以有效减少毛囊细胞受体与双氢睾酮的结合，这实在勿需争议，也因此有些生技公司会用来研发含有固相萃取的头皮配方，并也确实具有阻断双氢睾酮的功效。回到老问题身上，一定有效？多有效？怎么预期效果？那当然还是要看自己掉发的情况如何。如果是初期的雄性秃，外用锯棕榈不失为一个非药物的替代方案，合理的预期效果一样是缓和掉发或是长回部份头发，当然也可能效果不彰。如果已经是较为严重的雄性秃（四期以上），那锯棕榈也不可能有明显的效果了。此外，锯棕榈若用来搭配落建若是柔沛（波斯卡），也有相辅相成之效，但就要先衡量自己的经济能力了。
下面是一些国外关于据棕榈的资料：
AW PALMETTO From Dr.RaztecThis is by far the most commonly recognized and discussed herb concerning the prostate. Before we even begin its discussion, I highly recommend reading the book entitled "Saw Palmetto: Nature's Prostate Healer" by Ray Sahelian, M.D. This is a marvelous book that discusses the prostate and how Saw palmetto and other natural nutrients can prevent prostate disease (BPH). Saw palmetto is a plant (dwarf palm tree) native to the United States. It has been used medicinally for over a century. Its first use was described in the medical literature in the 1800s. Early literature concerning Saw palmetto stated that it relieved symptoms ranging from prostate enlargement in men to gynecological problems in women, such as menstrual discomfort. It has even been described as a potential aphrodisiac. Saw palmetto contains hundreds of different substances that can account for its beneficial effects. Saw palmetto is usually distributed as a crushed berry or as an extract. The extract form contains most of the substances found to be effective in treating benign prostatic enlargement. The extract form has been shown to be more potent than the dried berry form. The extract, then, is the form of choice. There are many articles in the medical literature that establish the efficacy of Saw palmetto in treating benign prostatic hyperplasia. One of the most recent and prestigious articles is "Saw Palmetto Extracts for the Treatment of Benign Prostatic Hyperplasia: a Systematic Review" by Timothy J. Wilt, MD, MPH et al. It appeared in The Journal of the American Medical Association on November 11, 1998 [2]. The study clearly demonstrated that the use of Saw palmetto improved urinary tract symptoms associated with benign prostatic hyperplasia. It also demonstrated that Saw palmetto provided similar improvement in urinary tract symptoms when compared to drugs such as finasteride. Saw palmetto was associated with fewer side effects. Although the mean study duration (the period of time that participants were using Saw palmetto) was 9 weeks, participants were noticing positive results in as little as 4 weeks. Finasteride users commonly saw relief of symptoms after three months. The next three paragraphs are a bit technical, but some readers may appreciate the detail. Others may wish to skip ahead to the paragraph that begins, “It is clear that….” A total of 18 randomized controlled trials involving 2939 men who met inclusion criteria were analyzed. Treatment allocation concealment was adequate in 9 studies (i.e., they were single-blind tests), whereas 16 studies were double-blinded. The average duration of the study was 9 weeks. In comparison to the men in the placebo control group, men treated with the SP extract Serenoa repens (S. repens or Saw palmetto) showed a measurable improvement in urinary tract symptoms. The weighted average difference for patients treated with S. repens was -1.41 points with a 95% confidence interval of L2.52, -0.301, compared to the control group's weighted-mean difference of -0.76 with a 95% confidence interval of [-1.22, -0.32]. This represents a relative weighted mean difference of 46% (Here, a lower weighted-mean difference correlates with improved urinary tract function). The patients themselves provided self-improvement ratings in urinary tract symptoms that were highly correlated with their quantitative evaluations.
