What is a limitation of laser hair removal regarding hair types?

It cannot remove thick hair
It is ineffective on white or gray hairs
It works only on coarse hair
It is not effective for fine hair

The correct answer is: It is ineffective on white or gray hairs

The limitation of laser hair removal concerning hair types is that it is ineffective on white or gray hairs. This is due to the technology behind laser hair removal, which relies on contrast between the pigment in the hair and the surrounding skin. The lasers target the melanin (pigment) in the hair follicle; therefore, hair that lacks pigment, such as white or gray hair, does not absorb the laser light effectively. As a result, the laser cannot adequately penetrate to target the follicle, leading to ineffective treatment for those hair colors. In contrast, laser hair removal can be effective on dark, coarse hair because the increased melanin provides a clearer target for the laser energy. This is an important consideration for individuals seeking hair removal options, emphasizing the need for a consultation to discuss their hair type and color to determine if they are suitable candidates for the procedure.
