How long can the traditional manual razor blade last?

It is best to change it every three months. In fact, it depends on the frequency of head use and the number of beards. The beard is used once a day and a half on average, and it is changed once a month with the most common Geely double-layer blade. The front speed is still sharp after three months of use, and it can be used for about three months. It is estimated that the beard is few and thin and can be used for half a year. Judging from the lubricating strip of the cutter head, if the lubricating strip becomes dry and wrinkles become less, a new cutter head should be replaced.

The correct way to shave:

1, hot towel on face: hot water can soften beard, expand pores and make beard easy to shave.

2. Apply shaving foam: You can use pressing shaving foam products, which saves the time of manual foaming. Shaving foam has the function of lubricating and softening fibrous roots.

3. "Shave" the beard (with a manual razor): With the previous preparations, shaving will be smoother. First shave along the direction of beard growth, so as to shave off most of the beard and reduce the irritation to the skin, and then shave again against the direction of beard growth.

4. "Shave" the beard (using an electric shaver): Now the electric shaver has both wet and dry functions, which can reduce the friction on the face after applying shaving foam. Shaving is the same as manual shaving.
