First, read the English article below.

Hold a section of your hair in front of your face and look at the ends to see if you can spot any frayed edges, splits, or small white spots where your hair has split. Once your hair starts to develop split ends, the breakage will travel up the strand of hair until you cut it, so you’ll need at least a trim to fix the problem.  Other signs of damage include dryness, frizz, or a straw-like appearance. The more damage your hair has, the shorter you’ll need to cut it. Fine, straight hair tends to look flat when you wear it long. Choosing a shorter cut will add body, making your hair look fuller and healthier. A layered pixie, choppy bob, or a piecey crop are all great ways to add volume. The shorter your hair is, the more lift it will appear to have. Short hair is low-maintenance, but you have to spend at least a few minutes styling it each day. If you’re the type to rely on a ponytail or a messy bun for days on end, a short hairstyle could be more work than you’re used to.  Short cuts also require more frequent trips to the salon. You’ll need a trim every 4-6 weeks rather than the 3 months or so you can go between trims if you have longer hair. If you already style your hair every day, a short cut can save you time during your daily routine! Of course, whether to cut your hair or not is a highly personal decision, but if you’re facing hair loss, cutting your hair short can make the process easier. Whether it’s due to heredity, chemotherapy, or another condition, short hair can make your hair loss less obvious as you go through the process.   The length you choose is up to you, but a close crop is often popular for people facing hair loss. Avoid shaving your head all the way down with a razor, especially if your hair loss is due to an illness. If you cut yourself while you're shaving, you may be at an increased risk for infection.
