“脱发”的秘密，不是头皮中循环不通畅，不是毛囊堵塞，不是营养不良，也不是压力太大。

When those first patches of scalp start showing through, it's probably hard to care about why you're losing your hair. You just want to know how to make it stop.

Baldness blights the lives of millions of Americans, both men and women, young and old. If you're fighting hair loss, chances are you've heard - and possibly tried - every gimmick out there. When you're this desperate, it's easy to make a mistake that could end up costing you lots of hard-earned cash, or, worse yet, precious hair follicles you don't have to spare.

"As recently as 20 years ago, there was little medical science could do to halt the loss of hair due to hereditary hairloss," says Dr. Alex Khadavi, a board-certified dermatologist and hair-loss expert. "Today, it is possible to find effective natural treatments for hair loss, but first one has to wade through a sea of information and misinformation to find the treatments that work."

Don't fall prey to products that play on these hair-loss myths:

* Poor circulation causes hair loss. -Research shows that medications that increase blood flow to the scalp do not grow hair. As further proof to debunk this myth, Khadavi points out that hair transplanted to balding areas produces new hair growth, demonstrating that there is adequate blood flow to the area to support hair.

*Clogged follicles cause hair loss.- Clogged hair follicles lead to ingrown hair, not hair loss. Shampoos and other products designed to open scalp pores do not stop hair loss or promote regrowth of hair.

*Poor nutrition causes hair loss.- Healthy, well-nourished people still lose their hair and taking nutritional supplements will not regrow hair. There are many supplements for hair loss in the market but even if they have ingredients that have shown to be beneficial for hair loss one would have to take 20-30 pills a day to get enough of those ingredients to the hair follicles to make a difference.

*Stress causes hair loss.- Day-to-day stress does not result in hair loss, no matter how much you fight with your mate or how loudly your boss yells at you. Major stress like surgery or cancer could result in hair loss, but this is usually temporary and the hair will likely regrow without treatment once the stress has passed.

"Dihydrotestosterone (DHT) is one of the main drivers of hair loss,"Khadavi says. Naturally found in males and females, DHT plays a key role in development of male characteristics for both men and women. Some men or women, however, have a genetic propensity for DHT to "attack" hair follicles, especially those on the top of the head. Over time, DHT causes the follicles to become thinner, shorter and weaker, and eventually stops them from regrowing new hair.

Products that reduce the production of DHT and stimulate hair growth are more effective at fighting hair loss, says Khadavi, who has developed Revivogen, a line of products designed to fight hair loss based on scientific research. Specially formulated scalp therapy, shampoo and conditioner products work in concert to inhibit DHT and promote hair regrowth. These products are all-natural and have been scientifically proven to reduce hair loss and stimulate hair growth in both men and women.

当你的一小块头皮开始闪耀“光芒”，你可能就要意识到为什么你会“脱发”呢？你唯一想要做知道的就是怎样去停止“它”。

在美国受脱发困扰的几百万美国人，有男人也有女人，年轻的或者年长的都有。如果你正在与脱发做斗争，那么你或许听过“机会来了”-或者你也尝试了-但是总是不管用。当你深陷这种困境，你就会会很容易犯一个这样的错误，不舍得再发把辛苦的血汗钱，或者更坏的是不再珍惜你那宝贵的毛囊。

全球知名皮肤学者、脱发研究专家亚历克斯-哈达威（Alex Khadavi）博士说：“从20年以前直到最近，还没有找到阻止这种遗传性脱发的药物。不过今天，我们可能找到一种对付脱发的有效的而又自然的方法，但是只有最初在或对或错的信息中步履维艰才能最终找到这种有效的治疗方法。”

不要被基于以下“脱发学说”的产品所折磨：

*血液循环贫乏导致脱发——研究人员发现增加血液循环的药物并不能使光秃的头皮长出秀发。为了进一步揭穿这个伪科学，哈达威指出通过头发移植到光秃的部位可以长出新的头发，这就说明光秃的区域依然是有充足的血液循环来维持头发生长的。

*毛孔的阻塞导致脱发——毛孔阻塞阻止头发向内生长，而不是脱发。洗发香波和其他可以打开毛孔的产品并不能阻止头发脱落，也不能促进头发的再次长出。

*营养缺乏导致脱发——健康，营养状况很好的人们也依然在脱落头发，补充营养也不能使头发再次生长。市场上有很多治疗脱发的营养品，但是如果它们真的含有对脱发者必须的成分，脱发者只要一天吃上20-30个药丸就可以补充毛囊所需的这种成分，就应该能起到作用。

*压力导致脱发——日常的压力并不是导致脱发的原因，不论是你与老伴吵多少次架或者你的老板又对你多么大声的吼叫。像手术和癌症的重压可以导致脱发，但是这只不过是暂时的，你的头发在这种治疗上的压力过去后又可以重新长出来。

哈达威说“二氢睾酮是导致脱发的原因”。在男性和女性中，二氢睾酮对男女性征的发育都有重要作用。一些男性或者女性，具有二氢睾酮攻击毛囊的遗传性倾向，特别是攻击头顶的毛囊。随着时间的推移，二氢睾酮使你的毛囊变薄、变短、变脆弱和最终导致他们不能重新长出头发。

“通过减少二氢睾酮的生成和刺激头发生长的产品对治疗脱发是更有效果的。” Revivogen的发明者哈达威说。 Revivogen是基于科学研究的对抗脱发产品。特殊的头皮治疗，以及香波和其他相关调节产品共同作用抑制二氢睾酮的生成和促进头发的再生。这个产品都是百分百全天然的，并被证明对男女脱发患者都能达到减少脱发和促进头发再生的作用。
