What technique is described as removing all curl with the application of heat?

The technique described as removing all curl with the application of heat is the hard press. This method involves using a hot styling tool, such as a flat iron or a hot comb, to apply direct heat to the hair, effectively straightening it and eliminating any curls or waves present in the hair. The hard press is typically employed on textured or curly hair to achieve a smooth, sleek finish.

This approach is particularly effective because it involves the use of higher temperatures and thorough tension to ensure that every curl is subdued. The hard press is distinct from other techniques in that it aims for a completely straight result, rather than just reducing frizz or adding a slight wave, as might be the case with less intense methods.

Understanding the hard press is crucial for hair professionals, as they need to consider the client's hair type and health when applying high heat to avoid damage.
