One of the most worrying aspects of hair loss treatment is the tendency of so many people to seek solutions without first determining what has caused their loss in the first place.其中最令人担忧的方面，脱发治疗是趋势，所以很多人，以寻求解决办法，首先确定是什么原因造成他们的损失摆在首位。

At best, sufferers may waste money on inappropriate 'wonder cures' or even legitimate treatments that unfortunately are not suitable for their particular needs.在最好的，患者可能会浪费金钱在不恰当的'难怪医治'或即使是合法的治疗不幸的是，不适合他们的特别需要。 At worst, some people may be risking their health by self-prescribing powerful pharmaceutical drugs.在最坏的，有些人可能自己的健康冒险，自我强大的处方药品。 I don't have a problem with hair loss sufferers saving money by purchasing cheap generic drugs on the internet, but I feel strongly that they should at least seek confirmation from their physician that a given drug matches their individual needs.我手边没有问题，脱发患者节省金钱，购买便宜的非专利药品在互联网上，但我强烈地感到，他们至少应该求证他们的医师说，鉴于毒品比赛他们的个别需要。

Before examining the most common causes of premature hair loss we need to understand that some shedding of hair is perfectly normal.在审查最常见的原因过早脱发我们要明白，有些脱落的头发是完全正常的。 Hairs grow from follicles that are tiny organs in the skin designed to grow a single hair that follows this repetitive cycle:毛发成长，从卵泡是微小的器官在皮肤设计的成长一个单一的头发如下这个重复周期：

1. 1 。 Lengthy growth period (Anagen Stage) - this phase usually lasts between two and seven years with an average growth rate of six inches (15cm) each year.冗长的增长期（ anagen阶段） -这个阶段通常会持续两至七年，与1的平均增长率六英寸（十五厘米）每年。

2. 2 。 Short transition period (Catagen Stage) - this period of transition lasts for roughly two to four weeks.短暂的过渡期（ catagen阶段） -这个过渡期为期大约2至4星期。 During this phase the hair shaft becomes detached and moves upwards within the follicle.在这一阶段，毛将焉轴成为超脱和动作向上内部的卵泡。

3. 3 。 Resting period (Telogen Stage) - this phase lasts about three months allowing the hair to detach itself prior to falling out.休息期间（休止期） -此阶段持续约3个月让头发摆脱前下降。

At this point a new hair begins to grow thus repeating the normal cycle of hair growth.在这一点上一个新的头发开始成长，因此，重复的正常周期的毛发生长。 Unfortunately a number of factors can interfere with the natural hair growth process leading to forms of hair thinning or premature baldness.不幸的若干因素可以干预自然的毛发生长的进程，导致形式的头发稀疏或过早秃发。

Androgenetic alopecia is the most common cause of hair loss, probably accounting for as much as 95% of pattern hair loss for both men and women.雄激素性脱发是最常见的原因脱发，大概占高达95 ％的格局脱发不论男女。 It is usually associated with aging and develops in predictable stages over varying periods of time.这是通常与老化和发展，在可预见的阶段，不同时期的时间。 Each follicle follows a genetically programmed growth cycle with some follicles coded to remain active for a shorter time than others.每个卵泡如下基因编程的增长周期与一些卵泡编码保持活跃，为更短的时间内比别人。 This results in the development of the hereditary baldness patterns that are so familiar to us all.这一结果在发展的遗传性秃发模式非常熟悉了我们所有人。

For this type of baldness to occur, the following factors must be present:针对此类型的秃发发生，以下因素必须在场：

1. 1 。 A genetic predisposition for hair loss to occur (as explained above). 1遗传易感性为脱发发生（正如以上所解释的） 。

2. 2 。 The presence of male hormones.在场的男性荷尔蒙。

3. 3 。 Aging - in other words, enough time for the first two factors to exert an influence.老龄化-换句话说，有足够时间前两个因素施加影响。

All men and women produce male hormones such as testosterone and DHT.所有男子和妇女产生男性荷尔蒙，如睾酮和dht 。 These have a useful role to play in both sexes but obviously occur in widely differing concentrations.这些都有益的作用，发挥在男女双方，但很明显发生在各种不同的浓度。 It is the higher levels of androgens found in males that explains why this form of hair loss affects men more than women.这是更高层次的发现，雄激素在男性解释为什么这种形式的脱发影响男性多于女性。

In brief, these hormones affect the hair growth cycle as follows:简言之，这些激素的影响毛发生长周期如下：

1. 1 。 High levels of the 5-alpha-reductase enzyme occur in some cells of the hair follicle and sebaceous glands.高水平的5 α -还原酶的酶发生在某些细胞的毛囊和皮脂腺。

2. 2 。 5-alpha-reductase converts testosterone into DHT. 5 α -还原酶睾酮转换成dht 。

3. 3 。 DHT causes the terminal hairs to miniaturize. dht原因，终端小型化毛发。

4. 4 。 This leaves short, soft, fluffy vellus hairs that provide inadequate scalp coverage.这使得短，软，头发蓬松vellus提供不足，头皮的覆盖面。

5. 5 。 The growth phases gradually become shorter until these hairs are lost for good.增长阶段，逐渐成为较短，直到这些毛发是失去了为好。

Alopecia areata is thought to be an immune system disorder that causes follicles to stop producing hairs in patches on the head.斑秃被认为是一种免疫系统紊乱，导致卵泡停止生产毛在几阵头。 In severe cases it can advance to the stage where all hair on the head is lost (alopecia totalis) or even a complete absence of body hair results (alopecia universalis).在严重的情况下，它可以事先向阶段，所有的头发对头部是失去了（脱发totalis ）或什至完全没有体毛的结果（脱发universalis ） 。

In most cases the hair will reappear on its own but until then, the condition can be very distressing to sufferers particularly as its cause can be difficult to determine.在大多数情况下，头发会重新出现在自己的，但直到那时，条件可以是很痛心的患者，特别是作为其原因可能是难以确定。 If you feel you may be suffering from this form of hair loss, seek the advice of your physician who will carry out a physical examination and conduct blood tests to help determine the cause.如果您觉得您可能患有这种形式的脱发，请教你的医生谁，将进行一次身体检查，并进行抽血化验，以帮助确定原因。

Telogen effluvium is characterized by a general thinning or shedding of hair over a period of months and is most commonly found in people who have recently experienced trauma.休止臭气的特点是一般间伐或脱落的头发，一个时期内是最常见的发现，在人们谁最近所经历的创伤。 Common causes include childbirth, major surgery, severe illness, psychological stress and chemotherapy.常见的原因包括生育，大手术，严重的疾病，心理应激和化疗。 The good news is that the abnormal growth behavior associated with telogen effluvium is temporary and reversible.好消息是不正常的生长行为与休止臭气是暂时的和可逆的。

There are numerous other less common hair loss causes that need to be discounted before a course of treatment is chosen.有很多其他不太常见的脱发原因，需要加以折扣之前，一个疗程的治疗选择。 Traction alopecia is the loss of hair from constant pulling, usually as the result of hair styling.牵引脱发是毛发脱落，从不断拉动，通常作为的结果，发型设计。 Broken hairs can result in thinning, often caused by excessive styling or exposure to chemicals and sun.打破头发可以在变薄的结果，往往造成过度的造型，或接触化学品和Sun 。 Finally, severe illnesses or nutritional deficiencies can cause side effects that may include degrees of hair loss.最后，严重的疾病或营养不足，可产生副作用，这可能包括程度的脱发。

I hope this brief article has gotten across the message that diagnosing the real causes of hair loss is not always a straightforward process.我希望这简短的文章得到了全国各地的讯息诊断的真正原因，脱发并不总是一个简单的过程。 Once you and your physician have identified a cause, then you can work towards restoring your hair to its former glory.一旦您和您的医生已经确定了的原因，那么你可以努力恢复你的头发其前的辉煌。 And the good news is, most forms of hair loss can be treated successfully.和好消息是，大多数形式的脱发是可以治疗成功。 The next article in this series will look at some of the best hair loss treatments currently available.在未来的文章，在这一系列将看看一些最好的脱发治疗方法，目前可用的。
