This is the case of a density effect tricopigmentation performed with hair long 3 cm. The level of coverage obtained is the highest possible if the aim is to maximize the natural effect and the covering power of the treatment. A higher coverage may lead to an unrealistic-looking result.
The hair length of 3 cm is the toughest one to manage because it is too short to create great volume and because there is not enough hair to make the result look homogeneous without tricopigmentation.
