What is the ideal temperature range for a perm solution?

The ideal temperature range for a perm solution is 70°F to 85°F. Within this range, the perm solution can effectively alter the disulfide bonds in the hair, allowing for successful curls or waves without causing damage to the hair structure.

When temperatures drop below 70°F, the chemical reactions necessary for the perm process slow down, which may result in inadequate processing and subpar results. Conversely, temperatures exceeding 85°F can increase the risk of hair damage or over-processing, leading to brittleness or breakage.

Therefore, the chosen temperature range ensures the perm solution works optimally to achieve the desired texture while maintaining the integrity of the hair.
