在炎热的夏季，人们往往会选择轻盈、简洁的发型来缓解高温。2021年夏天，不仅是短发流行，也是各种创新和个性化风格并存的一年。在这个时节，女性们纷纷抛弃了长发，而男生们则开始尝试各种新颖的染发技巧。

一、女性短发造型

females were quick to abandon their long locks in favor of shorter styles, and the trend was led by celebrities and influencers. The pixie cut, a classic style that has been popular for decades, saw a resurgence this summer. It's easy to see why: short hair is not only cooler in the heat but also requires less maintenance than longer styles.

The bob, another timeless favorite, also made an appearance on many runways and red carpets. This versatile style can be worn straight or with subtle waves, adding volume at the roots for added texture. Some bobs even featured asymmetrical cuts or fringe (bangs), giving them a fresh twist.

In addition to these classic looks, some women opted for more daring styles such as undercut hairstyles or shaved sides with longer hair on top. These edgy looks are perfect for those who want to make a statement without going full-on punk rock.

二、男性染发技巧

As men began embracing change in their hairstyles as well, dyeing became an increasingly popular way to express individuality and stand out from the crowd. Neon colors like green and blue were especially trendy this summer - think neon pink highlights paired with black hair or electric blue tips against jet-black strands.

For those looking for something a bit more subtle yet still eye-catching, ombre effects were all the rage. From soft pastel hues transitioning into darker shades at the ends to bold color blocks separated by stark lines of contrasting color - there was no shortage of creativity when it came to men's hairstyles this season.

Another technique gaining popularity among males was balayage - an artistic freehand application of lightener used sparingly across sections of hair rather than applied uniformly throughout its entirety like traditional highlights would be applied. Balayage gave off an effortlessly sun-kissed look that seemed both natural yet stylishly modern.

三、单马尾与微波卷

Single braids held court alongside micro-waves as two other prominent trends seen during 2021’s hot summer months.

Single braids offered versatility; they could be adorned with beads or charms depending on one's preference while remaining sleek and chic.

Micro-waves however provided movement & flow; loose curls cascading down ones back proved incredibly flattering under warm weather conditions when teamed up with minimal makeup allowing one’s natural beauty shine through unobstructed by heavy layers of cosmetics.

As we move into fall season now after what feels like interminable heat wave period,

it will be interesting seeing which hairstyles continue gain traction over next few months

and how people adapt these summer trends towards colder climates while retaining their essence intact
