Korean drummer Kang Min Hyuk's hairstyle

Drummer of the popular boy band, CNBLUE: Kang Min-Hyuk! And his sloppy hair!
Haha... No.. Not really his real hairstyle on the stage.. His usual appearance is in a medium long hairstyle, with sparkling earrings to finish it up.
If you look closely, Kang Min Hyuk actually has a round shaped face.  And it somehow fits him perfectly with this kind of long hairstyle, covering up one eye. This is definitely really stylish for an Indie Band drummer like him! :)
Now now, he seldom appears on stage with a shorter haircut, but when he does, he gets all the fans wild. =)
Wow, look at this adorable puffy haircut in the drama, HeartStrings... That drama also starred CNBLUE's lead singer, Jung Yong Hwa as well! 
Pretty hot choice of hairstyle for a popular Korean drummer..

CNBLUE Lee Jong Hyun's stylish hair

Born on May 15, 1990, Lee Jong Hyun is another guitarist in the popular South Korean boy band, CNBLUE, with Leader Jung Yong Hwa.
Born with an oval shaped face, Lee Jong Hyun occasionally has really short,  yet thick hair. But you could tell his hair dresser really put a lot of effort to trim up his fringes to have distinct layers.
Wow, look at his hairstyle at his first debut~ It's super thick and wavy length.. This kind of hair quality requires a full treatment of perm and hair wax.
Here's another one of those Kim Bum haircuts... =P This kind of hair is very flat and easy to manage.
This particular angle of Lee Jong Hyun in dyed red hair and full length fringes resemble Taecyeon's style.. In fact, he looks a lot like him when you stare at it for a couple seconds!

Popular boy Jung Yong Hwa

There has been a lot of demand for a review of Jung Yong Hwa's hairstyles. For those who don't know, Jung Yong Hwa is the leader of the super hot South Korean band, CNBLUE. He also stars in many popular K-dramas like HeartStrings with Park Shin Hye.
Born on June 22, 1989, Jung Yong Hwa is one of the few Korean stars who is blessed with an oval shaped face. He is able to pull off any kind of hairstyle: from short to even medium haircuts.
Jung Yong Hwa's role in the super hot drama, "HeartStrings", also known as "You've fallen for me" (English drama title), depicts him as a super cool guitarist/lead singer in a rock band. He has this kind of haircut, a dyed brown medium length hairstyle.
Here, we have Yong Hwa in a super long hairstyle. But isn't it weird to see him without earrings? Because in almost every photo you find of Jung Yong Hwa, he will have really baller earrings. :)
Gotta say, one of the hottest guitar leads in South Korean boy-band history! :)

ulzzang!!!

Girl next door hairstyle

Born on February 18, 1990, Park Shin Hye is a famous South Korean actress best known for her recent  leading role in the super hot drama, Flower Boy Next Door. Although having a heart shaped face, Shin Hye is able to pull off any kind of hairstyle: from short haircuts to long hairstyles.
Often in K-dramas, Shin Hye has wavy, short hair to portray her cute personality in the storyline. But in real life, she can definitely pull off a long hairstyle that defines her as a mature lady.
Outside of dramas, Park Shin Hye's hairstyles usually avoid long fringes, but exposing her whole forehead completely.
Now here is one of Park Shin Hye's typical haircuts. The short and puffy hairstyle with long bangs, like the next door flower boy's haircut. :)
Who said a short hairstyle cannot be hot? Park Shin Hye's defined face shape can help her pull off a perm short hairstyle.

Next Door Flower Boy's haircut

Also known as Yoon Shi Yoon, the male star of the recent hot Korean drama, Flower Boy Next Door, is known for his Round face and legit hairstyles.
With that kind of face shape, it is very appealing to pull off a thick, medium length hairstyle. Shi Yoon usually keeps his fringes over his forehead to have that "Rich boy" look.
Even his usual hairstyles outside of dramas is like this one above. His has his hair bangs go all the way to his upper jaws.
A lot of his fans would say his medium hairstyle looks best even when it is dyed light brown. Yoon Shi Yoon can definitely pull off this kind of hot hairstyle!!
From what you can see, this medium length hairstyle is definitely Shi Yoon's signature haircut! From a hairstylist's view, this haircut deserves:

9/10 for his trendy style 
1010 for the maintainability of his haircut 
9/10 for the length of his haircut according to his face shape

Even if you have a different face shape like the diamond face, it isn't extremely difficult to wear this kind of hairstyle. That is why Shi Yoon's haircut gets a 10/10 for the maintainability of this hairstyle. You would really need to consult with your hairstylist to get your hair perfectly trimmed for other face shapes.

Taeyang's haircut: Sloppiest haircut of all time!

It has been almost a decade since Korean singer Taeyang has cut his hair. Most Taeyang fans will most likely agree with me. As a big fan of Taeyang, it seems pretty disappointing how Taeyang is pretty slack with his hairstyles.
Although Taeyang possesses one of those unique square shaped faces, he is always seen in his "official" haircut: the extremely short onion haircut.
"Onion" haircut as in: shaving 95% of your head, leaving the front 5% of the top forehead with a traditional "fohawk".
However, one aspect Taeyang's haircut is good for is having the impression of clean and lean.

Now, back to the actual reviewing of the onion haircut:

In the current Kpop industry, most guys often wear the popular medium haircut with bangs. This makes Taeyang's haircut fairly unique and classy. However.... It's called sloppy as soon as the Kpop idol wears the same haircut for over 5 years. I mean, it will be nice to have Taeyang having a Kim Bum hairstyle sometime.. Not only does Taeyang's haircut look like it was quickly shaved in 5 minutes, without any effort, but it also reflects on his style as well. It gives an impression that the onion hair was never polished up at all.

To be frank, Taeyang's haircut:

Lacks style (considering the amount of time he has had this haircut)
This is going towards a 6/10 for style
10/10 for maintainability (You don't even need to maintain it!)
5/10 for the short length (there's not much thickness and length to his hair, it's heading towards bald)

To conclude, Taeyang's hairstyle is pretty nice overall, as long as you don't put on this hairstyle for years in a row.

The 2AM Seulong's sharp haircut

Hottest member of the Kpop boy group, Seulong Im, who specializes in the vocal part of the group. Today we will be reviewing his unique haircut.
Clearly, Seulong's hairstyle looks like another ordinary short haircut, but look closely. You see it is nicely trimmed up so that it's actually weighing on the heavy, thick side.
His fringes and sides are actually folding downward toward his skin. That means it's relatively thick. This kind of haircut is hard to maintain especially one would have to get it trimmed up precisely, not to make it look too bushy.
Notice how Seulong's face shape is falling onto the triangle shaped category. Seulong is doing rather a great job of balancing out his facial features, especially his face shape.
Clearly, this IS Seulong's signature haircut! From looking at his relatively "unique" hairstyle this is the concluding review:

8/10 for his trendy style
6/10 for the maintainability of his haircut
9/10 for the short length of his haircut according to his face shape
