Detailed answer

Hair loss treatments typically target the scalp and do not directly affect the skin on the body. However, if a particular hair loss treatment contains ingredients or chemicals that are harsh on the skin, it is possible that it may cause some irritation or sensitivity. This could result in temporary redness or inflammation, which may contribute to the appearance of uneven skin tone. It is always recommended to carefully read and follow the instructions provided with any hair loss treatment, and to consult with a dermatologist if you have concerns about how it may affect your skin.
