Influencing factors of hair quality:

The first is external factors-living environment, hair growth environment. Don't pollute the air, it is full of dust. Stay in the oil mist environment for too long. Also pay attention to the relative humidity of the air, the air temperature is about 25 degrees. Hair is difficult to adapt to the hot and cold environment, and the temperature contrast is large. Let the hair lose its resistance.

Second, it's my own reason-whether my hair is dry, neutral or oily. If you are oily, you must wash your hair once a day. If you want to improve your hair quality, you must make proper self-regulation and protect your hair. Choose the right shampoo and conditioner. Vitamin B2 and B6 supplements. Eat more fruits and drink more water. Take part in more physical exercise.

The third is the internal factor-good mood will also affect it. Many times, mediating one's emotions and maintaining a good mood can relax the brain, relax the head and give the hair a better growth environment.
