Hair that is Fine typically requires the shortest processing time in chemical waving as it has a smaller diameter and is more delicate, making it more susceptible to damage from the chemicals. Coarse hair, on the other hand, has a larger diameter and is more resistant to chemical penetration, so it may require a longer processing time. Thick and long hair can also take longer to process due to the increased amount of hair to be treated. However, the specific processing time may also depend on the type and strength of the waving solution used.
