With the reckoner below,you can learn , you can learn nearly needed greft numbers to cover required areas.
While calculating, consider these factors:
Thickness of hair : Is your hair thin or thick? High density is needed for thin hair.
Hair colour: Blond hair and other fair hairs requires less density because of less colour difference between hair and skin.
Structure of your hair: Wavy and curly hair closes more than straight hair. So less density is needed.
The hair cultivation areas: Forehead line and area requires more dense hair cultivation in principle
Average hair density is about 60-100 follicles for every square centimeter for unspillaged hair. To have a good density, it is achieved with 30-50 follicle grefts for every square centimeter depending on the factors above.
