What is a common requirement for clients before undergoing laser hair removal?

Shaving the treatment area is a common requirement for clients before undergoing laser hair removal because it helps to ensure the treatment is effective and safe. By shaving, the hair is shortened to the surface level, which allows the laser to target the hair follicle without interference from longer hair above the skin. This minimizes the risk of burning the hair above the skin's surface and focuses the energy on the root of the hair where it can be most effective.

Shaving also helps in reducing discomfort during the procedure and improves the precision of the laser. When longer hair is present, it can absorb heat and create a risk of skin damage. Therefore, clients are typically advised to shave the treatment area a day or two prior to their session, ensuring the skin is prepared for the laser's effectiveness.
