护发精华会加速头发生长吗

With an endless number of hair products to buy, it can be confusing to decide which one is best for you. Hair serums are leave-in treatments that promise to help with hair growth, length, moisture, and more. But do these products really work? Ultimately, it depends on the product itself and its intended use.

有无数的护发产品可以买，决定哪一款最适合可能会让人困惑。头发精华液是一种免洗的治疗方法，承诺有助于头发的生长、长度、水分等。但是这些产品真的有用吗?最终，这取决于产品本身及其预期用途。

According to Byrdie, any hair serum treatment that promises to make your hair grow faster is getting your hopes up for nothing. "The maximum rate to which your hair will grow is genetically determined," said trichologist Anabel Kingsley. "For most people, this is approximately half an inch a month, and unfortunately there's nothing you can do to speed this up." The key to healthy hair growth is a healthy scalp. Some hair serums may contain ingredients that improve scalp health, but how well they work depends on the concentration of ingredients and how they are created in the product. Hair growth serums are most likely to show improvement in hair growth if they contain ingredients like minoxidil, niacin, arginine, and polyphenols, which increase blood flow to the scalp.

根据Byrdie的说法，任何能让头发更快生长的护发素治疗都会让人失望。毛发学家阿纳贝尔·金斯利(Anabel Kingsley)说：“头发的最大生长速度是由基因决定的。”。“对于大多数人来说，大约是一个月半英寸，不幸的是，你无法加快这一速度。”健康头发生长的关键是健康的头皮。一些头发精华液可能含有改善头皮健康的成分，但它们的效果取决于成分的浓度以及它们的生成方式。如果毛发生长血清含有诸如米诺地尔、烟酸、精氨酸和多酚等成分，可以增加流向头皮的血液，那么它们最有可能改善头发生长。

According to Healthline, you're more likely to find success with a hair serum if it is fighting surface level hair issues like frizz and dullness. Hair serums designed to treat these problems often contain some kind of oil and coat each strand of hair when used. Silicone is a common serum ingredient because it can coat your hair and effectively reduce frizziness caused by dry or damaged strands. Silicone can also make curls look more defined. Its silky effect often makes hair look shinier and smoother.

根据Healthline的说法，如果一种护发液能够对抗表面的头发问题，比如卷曲和发暗，那么你就已经成功了。用于治疗这些问题的头发精华液通常含有某种油脂，在使用时会覆盖每根头发。硅树脂是一种常见的精华成分，因为它可以覆盖你的头发，有效地减少因头发干燥或受损而产生的卷曲感。硅胶还可以使卷发看起来更清晰。它的丝滑效果常常使头发看起来更有光泽和光滑。

Other hair serum treatments are designed to protect your hair against damage caused by styling tools, chemical processing, and sun exposure. These need to be used before your hair is exposed to whatever could potentially damage it. For example, a heat-protectant serum applied to your hair before you use a curling iron will protect your strands from being burned or dried out from the heat of the styling tool.

其他护发素旨在保护您的头发免受造型工具、化学处理和阳光照射造成的伤害。在你的头发暴露于任何可能对它造成伤害的东西之前，需要使用这些。例如，在您使用卷发器之前，在头发上涂抹一种热保护精华，可以保护您的发丝不被烫伤或因造型工具的热量而变干燥。

There are many hair serums available. To find one that works, look for trusted brands and high-quality ingredients. When applying a serum, work a small amount through your hair beginning at the ends and working your way toward the roots. Avoid putting serums on your scalp unless they are designed for that area, as this can make your hair look oily and unkept.

市面上有很多护发素。要找到一个有效的产品，就要寻找值得信赖的品牌和高质量的配料。涂抹精华液时，从头发末端开始，向发根方向涂抹少量精华液。避免在头皮上涂抹精华液，因为这会使你的头发看起来油腻和凌乱，除非它们是专门为头皮设计的。
