How to cut your own blunt bangs korean style

There are so many onnline vidoes showing you how to cut your fringe/bangs at home korean style. I noticed most of them dont really explain why,  not to mention explaining the different length for different face types. I am not professional, but in my videos, I like to explain why. Each person is unique, same hair style won't look good on everyone. Same as products review, the buyer doesnt just want to know about the product, they care more about if it is going to work for themselves.
Here are my 2 cents thoughts. My way of cutting my own blunt bangs is rather easy. 
step 1. Section the hair
Everyone talks about the triangle shape, which is what you are supposed to do. COMMON MISTAKES:  But I noticed most people only pull the front part of hair near the hairline. Doing so will give you a whispy bangs. If you have fine hairs, you really want to pull more hairs from back. The thicker you want your bangs to be, the further of hair you should pull.
Speaking of the triangle, the sides frame your face. If the top of your head if wide like mine, your want your triangle look narrow instead of wide. Just imagining after you finish cutting, the narrow the triangle is, the less volume hair on the sides is.
step 2. Cut and trim
I put 2 steps together as the first step only takes one second. Instead of holding a fine comb in one hand, what I do is hold my bangs with a large hair clip. Twist the bangs twice and clip. Then cut. Twisting is so the bangs won't be all the way straight across, which gives the sides a nice angle. This is especially important for square face.
Hold the shear vertically and soften the edge. COMMON MISTAKES: Holding shear horizontally.
Step 3. Using Hair Straightener to curve the bangs like koreans
Since my hair is too thick and hard, it falls right in front of my eyes. looking from the side, my forehead is flat. So to add some volume to my bangs, I use panasonic 2 way hair straightener to curve the bangs. The size is perfect to style my bangs. and it won't damage your hair!
