I know, But my question is if the white hair presence affect the removal of other hair in the same area? is it possible that the melanine is low in this area?
hair gets its natural color from a type of pigment called melanin. The formation of melanin begins before birth. The natural color of our hair depends upon the distribution, type and amount of melanin in the middle layer of the hair shaft or cortex.
Melanin is made up of specialized pigment cells called melanocytes. They position themselves at the openings on the skin’s surface through which hair grows (follicles). Each hair grows from a single follicle.
As the hair is being formed, melanocytes inject pigment (melanin) into cells containing keratin. Keratin is the protein that makes up our hair, skin, and nails. Throughout the years, melanocyctes continue to inject pigment into the hair’s keratin, giving it a colorful hue.
With age or certain factors comes a reduction of melanin. The hair turns gray and eventually white
Due to the fact that a laser targets melanin, the more melanin an individual has in his/her hair, the more effective a laser will be.so having an area with dark and white hair ,the laser will target the dark hair containing melanin and no change in white hair color containing no melanin
