What is the primary risk associated with using powder lighteners?

Using powder lighteners primarily poses a risk of burns on the scalp due to the high concentration of chemicals involved. Powder lighteners often contain strong oxidizing agents that can lead to chemical reactions that elevate the temperature of the scalp, particularly if the product is not evenly distributed or if it is left on for too long. These burns can result in irritation, discomfort, and even more severe skin damage if proper precautions are not taken during the application process.

While hair damage, allergic reactions, and dry hair are also concerns associated with the use of lighteners, they do not represent the immediate and acute risk that burns present during the application. Proper technique and precautions, such as performing a patch test and ensuring even product distribution and timing, can help mitigate the risk of burns while still allowing for effective lightening results.
