爲什麼你的頭髮不長了?大綱

At one point or another, all of us have looked in the mirror and thought, "Ugh, why the hell won't my hair grow?" - but can hair really stop growing, or is it all in our inpatient minds?

某時某刻，我們所有人都會一邊照着鏡子一邊想着，"哎，我的頭髮爲什麼就是不長了呢？"--但頭髮真的會不長嗎？還是隻是我們不夠耐心呢？

While it's true that your hair probably hasn't stopped growing altogether, there are some factors that can slow the growth or make it seem like the growth has been stunted. We checked in with experts and they gave us this master info as well as some tips on how to help things along.

雖然你的頭髮可能還沒有停止生長，但有些因素會拖慢頭髮的生長速度，就好像你的頭髮不長了一樣。我們諮詢了一些專家，他們向我們提供了專業信息和小建議，讓我們的頭髮茂密生長。

Are you getting trims often enough?

你是不是經常修頭髮？

"Some women try to hang onto as much length as possible by avoiding haircuts, and yet they gain no length," says Shab Aghajani, Roy Teeluck Salon stylist. "We all have a maximum length our hair can reach according to our current regime. This is where your ends simply begin to break instead of continue to remain strong and healthy. Until you change your existing habits and products used on your hair, nothing will change about your hair. Trim the split ends, and use the right hair mask and treatment to nourish your hair, because clearly you've plateaued and nothing will change unless you make some changes yourself."

"有些女性總是不剪頭髮以儘可能的使頭髮長長，但實際卻一點兒沒長，"羅伊狄拉克美容院造型師Shab Aghajani說道。"根據現狀，我們每個人的頭髮都有生長限度。所以你的頭髮會開始分叉，而非繼續柔韌而健康。除非改變現在的習慣和護髮產品，否則你的頭髮不會發生任何改變。修剪分叉的頭髮、使用正確的發膜和護髮產品，可以滋養頭髮，因爲很顯然，你的頭髮已形成固定模式，除非你作出改變，否則什麼變化都不會發生。"

Genetics

遺傳

Whether we have pinpointed it or not, we all have an individual hair cycle growth phase in which their hair has potential to reach its longest.

無論我們是否曾明確指出，但我們每個人都有各自的頭髮生長週期，並且頭髮有可能長到最長長度。

"This does not mean that hair always stops growing once it reaches a specific length, but once a certain amount of time has passed. The growth phase is largely determined by genetics and typically lasts between two and six years," says Dr. James C. Marotta, plastic surgeon and hair restoration specialist.

"這並不意味着頭髮長到一定長度就會不長了，但一旦特定時間過去了，頭髮就會停止生長。生長階段主要受遺傳影響，通常持續2至6年，"整形醫生和頭髮修復專家詹姆斯· C· 馬羅塔醫生說道。

Age

年齡

Aging brings with it a host of life complications, not the least of which is our hair. As we get older, chances are our hair is weaker. Years of heat styling and bleaching can build up to create major damage.

衰老會帶來一系列的生命併發症，其中最重要的就是我們的頭髮。當我們年紀越來越大，我們的頭髮就會越來越弱。長年燙髮、漂染都會對我們的頭髮造成重大損傷。

"Studies have shown that the biology of hair can change and the growth stage may shorten. This means that hair could begin shedding faster, making it appear thinner and shorter," says Marotta. "For instance, if you have a five-year anagen (growing) period, a single strand of hair will continue growing for five years before it will go into 'resting' phase. "

"研究已表明：頭髮的機理會發生變化，生長階段可能縮短。這就是說我們的頭髮會脫落得更快，因此會更薄、更短，"馬羅塔說道。"例如，如果你的頭髮生長階段是5年，那你的頭髮在進入'休息'階段前，還會繼續生長5年。"
