Which of the following describes a medical treatment method for scalp issues?

Laser therapy is indeed a recognized medical treatment method for various scalp issues, particularly for conditions like hair loss or thinning hair. This treatment uses focused light energy to stimulate hair follicles, promoting hair growth and improving scalp health. It is non-invasive and has been effective for many individuals seeking to enhance their hair density.

Electrolysis, on the other hand, is primarily a method for hair removal rather than a treatment for scalp conditions. Deep conditioning treatments and hot oil treatments are cosmetic procedures aimed at improving hair texture and hydration, but they do not address underlying medical conditions of the scalp. Hence, when considering treatments specifically designed to address scalp health from a medical perspective, laser therapy clearly stands out as the appropriate choice.
