40% of Men Under 40 Has Hair Loss!
If your once-thick hair is falling out in clumps, or if you have got bald patches peeking out from your scalp, you're not alone. More than 20 million women in the United States alone, 40 percent of them under age forty, are suffering from hair loss.
Hair Loss On Men
Male pattern baldness is a typical pattern of hair loss in men that is caused by genetics and hormones. Approximately 95 percent of all men who suffer some degree of hair loss do so because of male pattern baldness otherwise known as androgenetic alopecia.
Hair Growth Phases
1) Anagen
Growth Phase - Approximately 85 percent of the hair on your head is in the growing phase at any given time. This phase can last 2 to 6 years. Hair can grown at the rate of approximately 5 inches per year and any individual hair is unlikely to grow more than one yard long.
2) Catagen
Transitional phase. When the Anagen growth phase comes to an end, hair enters into a Catagen phase which lasts about one or two weeks. During this transitional phase, the hair follicle shrinks to about 1/6th of the normal diameter. The "root" is diminished and the dermal papilla breaks away and rests below the scalp.
3) Telogen
Resting Phase. After the catagen phase, hair goes into a resting phase known as telogen. This period can last five to six weeks. Although the hair does not grown during this stage, the dermal papilla stays in resting phase below the scalp. Approximately 10 to 15 percent of all hairs on your head are in this resting phase at any given moment. At the end of this stage, the hair follicle re-enters the growth phase. The dermal papilla and the base of the follicle join together again and a new hair begins to form. In some cases, the new hair will push the old hair out of the way and the hair growth cycle starts all over again.
Stress Disorders Leading to Hair Loss?
Trichotillomania, a psychological disorder that may be linked to stress, involves the compulsive pulling or twisting of hair, resulting in patchy or diffuse hair loss. This compulsion is thought to affect as much as 4 percent of the population, and it seems to affect females four times more often than males. This compulsion generally manifests itself before the age of 17 and is often limited to a period of a year or so. The earlier this compulsion appears and the sooner it is treated, the better the prognosis. Trichotillomania is not well understood, and some medical professionals believe that it is simply an ingrained bad habit, but it is sometimes treated with therapy and antidepressants.

40歲以下的男性40%有異常落髮！
如果你曾經濃密的頭髮掉下一大把，或如果你有圓禿，可以看見你的頭皮，你並不孤單。在美國，就有40％的人40歲以下，20多萬婦女患有脫髮。
男性脫髮
男性型脫髮是一種典型的模式，約有95％因為遺傳和雄性激素影響。
頭髮生長階段
1）生長期
生長階段 - 你的腦袋上的頭髮，約85％是在任何時間下在不斷發展的階段。這個階段可以持續2至6歲。頭髮可以成長率每年大約5英寸（1英吋 = 25.4公厘 = 2.54公分），任何一個人的頭髮是不太可能增長超過一碼長（1碼 = 36寸 = 91.44 cm）。
2）退化期
過渡階段。生長期的增長階段即將結束時，發進入一個的退化期持續大約一兩個星期的。在這個過渡階段，毛囊縮小到正常直徑約六分之一。髮根的減少是由於頭皮底下的毛乳頭脫離。
3）休止期
休息階段。退化期階段結束後，進入休息階段被稱為休止期頭髮。這個時期可以持續五到六個星期。雖然頭髮不生長在此階段中，毛乳頭於頭皮下停留於休止期。在你的頭上所有的頭髮約10％至15％是處於休止期狀態。在這個階段結束時，毛囊重新進入增長階段。毛乳頭和毛囊的基礎再次攜手，並開始形成一個新的頭髮。在某些情況下，新的頭髮將推動舊的頭髮的方式和頭髮的生長週期又重新開始了。
精神緊張性障礙（壓力）會導致脫髮嗎？
拔毛症，心理障礙，可能與壓力，包括強迫拉扯或扭曲的頭髮，導致斑片狀（區塊）或瀰漫性脫髮。高於4％的人被認為是受到這種強迫行為的影響，而這影響似乎女性高於男性四倍。這種強迫行為通常表現為在17歲之前，往往是有限的時間。強迫行為早些時候出現，越早治療越好。一些醫療專業人士認為，拔毛的行為沒有根據，這簡直是一種根深蒂固的壞習慣，但它有時會以抗抑鬱藥治療。
