What type of hair typically requires a milder perm solution?

Fine hair typically requires a milder perm solution because it is more susceptible to damage from harsh chemicals. Fine hair has a smaller diameter and less structural strength, making it more likely to become weakened or over-processed when exposed to strong perm solutions. A milder solution helps to minimize the risk of breakage and allows for a more natural, softer wave to be created without compromising the integrity of the hair.

Using a gentle formulation for fine hair ensures that the perm process can enhance texture without overwhelming the delicate strands. In contrast, coarse hair, thick hair, or color-treated hair often requires stronger solutions due to their increased resilience or specific needs for processing, which is why a milder alternative is less appropriate for those hair types.
