1. Prepare horn comb, glycerin and hand cream. Clean the horn comb with clean water (be careful not to use hot water) and dry it in time.

2. Drop a few drops of glycerin on the horn comb.

3. Slowly apply glycerin until the whole horn comb surface is covered, then put it in your hand and rub it constantly to ensure that both sides and comb teeth are coated.

4. After rubbing for a while, dry it with a dry paper towel and blow it in a ventilated place for a while. In front of you is a shiny horn comb.
