Virgin hair vs retouched hair: what is the key difference in chemical texture planning?

• A. Virgin hair has not had prior chemical processing; retouched hair has new growth; processing times and safety margins vary.
• B. Virgin hair is always darker.
• C. Retouched hair requires no processing.
• D. Virgin hair cannot be chemically treated.

Answer: (A)

The key idea is how the hair’s chemical history shapes texture planning. Virgin hair hasn’t undergone any chemical processing, so it responds to a texture service with a uniform, predictable reaction when you apply the chosen formula and processing time. Retouched hair has two different zones: new growth that is still virgin, and ends that have already been chemically treated. Because those ends behave differently—often being more porous or weakened—you must tailor the approach: adjust the product strength, shorten or vary the processing time, and set safety margins so the new growth can be processed properly without overworking the already processed ends. This distinction in history is why the option that states virgin hair hasn’t had prior chemical processing, retouched hair has new growth, and processing times and safety margins vary best captures the essential difference in planning.

Virgin hair isn’t inherently darker, and retouched hair still requires processing to ensure the new growth matches the treated ends; virgin hair can indeed be chemically treated.
