Why might some clients experience hyperpigmentation after hair removal?

Clients might experience hyperpigmentation after hair removal due to irritation or inflammation of the skin. When hair removal techniques, such as waxing or laser treatments, are applied, they can potentially irritate the skin, leading to inflammation. This inflammation can stimulate the production of melanin, the pigment responsible for skin color, resulting in patches of darker skin where the irritation occurred.

Hyperpigmentation is essentially the skin's response to trauma; it can occur even from minor irritations. Inflammation can trigger the skin's natural defense mechanisms, causing melanocytes (the cells that produce melanin) to be more active in the affected areas. Hence, as the skin heals from the hair removal process, the increased melanin production can lead to noticeable darker spots or patches.

While exposure to sunlight, improper aftercare, and genetic predisposition can also contribute to hyperpigmentation, the direct link between irritation or inflammation caused by the hair removal process is a significant factor in the immediate aftermath of such treatments.
