How should chemical relaxers be applied to minimize scalp irritation?

Directly on the scalp
Away from the scalp using a protective base
In small sections
By massaging into the scalp

The correct answer is: Away from the scalp using a protective base

Chemical relaxers should be applied away from the scalp using a protective base to minimize scalp irritation. This method is effective because the active ingredients in chemical relaxers can be quite harsh and may cause burns or discomfort when applied directly to sensitive skin. By placing a protective base, such as a petroleum jelly or specialized barrier cream, along the hairline and on the scalp, it acts as a shield that prevents the relaxer from coming into contact with the skin. This practice reduces the risk of chemical burns and irritation, allowing for a safer application process. Thus, the intent is to ensure that the relaxer is only applied to the hair shaft, where it can effectively break down the curl pattern without harming the scalp. Using a protective base is an essential technique in the chemical hair treatment process, emphasizing the importance of precautions in cosmetology to maintain client safety and comfort during procedures.
