What must be cut off before doing a curl reform?

• A. Hair Treated with Sodium Hydroxide
• B. Hair With Split Ends
• C. Hair Colored
• D. Hair Oily

Answer: (A)

The main idea is that chemical history and hair health determine whether a curl reform can be safely and predictably done. Hair that has been treated with sodium hydroxide is especially vulnerable because sodium hydroxide is a strong alkaline chemical that permanently alters the hair’s structure. When you encounter a curl reform, applying another chemical service on top of that compromised hair can lead to over-processing, uneven results, or breakage. Therefore, the ends that have been exposed to sodium hydroxide are trimmed off so the new curl work starts on healthier, more evenly prepared hair.

Split ends indicate damage but aren’t the specific reason to cut before this service. Hair that’s colored or oily isn’t inherently prohibited from proceeding, but they’re not the deciding factor for trimming in this context.
