You can cut your hair whenever you want. It used to be said that you can't cut your hair on the fifteenth day of the first month. This statement was made up by the Han people after the Qing dynasty entered the customs, so at least you can not cut your hair in the first month. In the new society, there are not so many superstitions. Cut it when you cut it.

Hairdressing, also known as hairdressing, has developed from shaving in the Qing Dynasty to modern hairdressing such as haircut, beauty, hairstyle design and perm. In fact, the development history of hairdressing is completely inseparable from the development and progress of fashion and hairdressing products.

The more expensive the hairdressing products, the better. Hairdressing products have different ingredients according to the needs of different hair qualities. For example, products for damaged hair are generally more expensive, but they are not suitable for normal hair. Therefore, the products that are most suitable for consumers' hair quality are not necessarily the most expensive products.

If you can know the arrangement of the evening in advance and you want to get a hairstyle, then don't wash your hair this morning, because the stylist thinks that hair with a little natural oil is the easiest to do with your hairstyle.
