When applying a relaxer, the correct practice is to initially apply the product at least half an inch away from the scalp. This is important because the scalp is more sensitive than the rest of the hair, and relaxers can generate heat as they process. If the product is applied too close to the scalp, it can lead to irritation or chemical burns.

By starting the relaxation process half an inch from the scalp, you allow the heat to disperse, ensuring that the scalp remains protected while the treatment works on the hair that is further away. This technique ensures that the hair closest to the scalp, which may be new growth and finer, does not over-process and become damaged.

Other options, like applying directly on the scalp, could cause severe irritation, while applying only at the ends may not be effective for uniform relaxation of the hair. It's essential in cosmetology to follow safe practices that protect the client's scalp while achieving the desired results.
