From a scientific point of view, morning and afternoon haircuts have no significant impact on hair quality and growth. However, from a biological point of view, the body's biological clock will affect the growth of hair. The body's biological clock will affect the growth cycle of hair, so hair cutting at different times may have different effects.
Generally speaking, the body's biological clock has different states in the morning and afternoon. In the morning, the human body is in a sober state, and the blood circulation and metabolism are relatively active, so hair cutting may be more likely to stimulate the growth of hair. In the afternoon, the body's biological clock is in a relatively tired state, and blood circulation and metabolism are relatively slow, so hair cutting may be more likely to cause hair breakage and damage.
In addition, the body's biological clock is also affected by environmental factors, such as light, temperature, humidity, etc. Therefore, if you need to wait for a period of time before cutting your hair, it is better to choose a stable and comfortable time period for hair cutting.
In general, hair cutting in the morning and afternoon has no significant impact on hair growth and quality. However, if you want to minimize the damage and breakage of your hair, you'd better cut your hair in the morning. If your hair is fragile or needs complex modeling, you'd better choose a comfortable environment and a period of time in good condition for hair cutting.
