Corrective hair treatments primarily address which part of the hair?

Corrective hair treatments are designed to improve the condition of hair that has been damaged or compromised due to various factors, such as chemical treatments, heat styling, or environmental exposure. The hair shaft is the part of the hair that is typically treated during these procedures.

When applying a corrective treatment, products penetrate the hair shaft, aiming to restore moisture, strength, and overall health to the hair. These treatments often include deep conditioning, protein treatments, or bonding treatments that specifically target issues like brittleness, breakage, or dullness in the hair's structure and appearance.

The other choices focus on different parts of the hair or scalp. The roots are involved in hair growth and nutrient absorption but are not directly addressed by corrective treatments, which focus more on the visible and damaged sections of the hair. The scalp, while important in overall hair health and sometimes treated for specific conditions, is not the primary area of focus for corrective hair treatments. The ends of the hair are often considered in relation to split ends or dryness, yet the comprehensive conditioning in corrective treatments primarily targets the entire hair shaft for consistent improvement.
