What technique involves placing heat-resistant products on hair before styling?

The technique of placing heat-resistant products on hair before styling is associated with hair pressing. This technique is important because it helps protect the hair from potential heat damage caused by styling tools such as flat irons or curling irons. By using heat protectants, the hair remains nourished, smooth, and less prone to breakage or frizz.

Hair pressing specifically involves straightening the hair using heated tools, and applying these heat-resistant products beforehand allows for a more polished and healthier end result. This practice ensures that clients can achieve the desired sleek or styled look while maintaining the integrity of their hair.

In contrast, other techniques such as hair perming, hair curling, or hair straightening typically focus on altering the texture or shape of the hair, often without the same level of emphasis on heat protection products beforehand. Thus, hair pressing uniquely emphasizes preparation for styling with heat, making it the correct choice in this scenario.
