Factors affecting the number of hairs:

1. The area of ​​hair removal
• Smaller areas: such as lips and underarms, about 100-300 hairs are needed each time.
• Medium areas: such as arms and calves, about 500-1500 hairs are needed each time.
• Large areas: such as backs and thighs, 2000-4000 hairs may be needed each time.
2. The density of hair
Dense hair areas may require more hairs to cover, and sparse areas may require fewer hairs.
3. Equipment parameters
The coverage area of ​​the laser instrument and the energy of a single pulse determine the skin area that can be treated per hair. Efficient equipment may reduce the total number of hairs required.
4. Customer needs and treatment goals
Precise treatment of certain local dense hair may require higher coverage, so the number of hairs may increase.
