1, first distinguish chest hair.
In fact, many girls think they have chest hair, but if it is short, soft and light in color, it is normal hair, not chest hair, because in fact, most parts of the human body have long hair, which helps to dissipate heat and sweat. If you find that your chest hair is black, hard and thick, it is that chest hair has grown out. At this time, you should judge whether you should shave your chest hair.
2. Don't shave your chest hair at will.
If the chest hair is long, thick and hard, it may not look good at this time, but we still don't recommend girls to shave it off. Because human hair is actually composed of keratin, and the growth characteristic of keratin is that it can promote its growth after being cut short, so if you shave off the chest hair, it will promote the chest hair to grow faster and thicker, which is counterproductive, and the chest hair does not actually affect the appearance.
3. It may be a hormonal problem.
If a girlfriend has thick and hard black chest hair, it may be abnormal in many cases, because a woman's own hormone level can't cause her to have chest hair, which is determined by genes, so it may be that there is something wrong with her endocrine system and she needs to see a doctor for examination. Generally, most of them are hormonal problems, which can be adjusted by drug treatment or changing living habits. For example, avoid foods that affect hormones in the diet and strengthen exercise.
