Which type of waves produce a firmer curl and process more quickly than true acid waves?

The type of waves that produce a firmer curl and process more quickly than true acid waves are acid balanced waves. Acid balanced waves have a pH that is nearly neutral, typically ranging from 6.9 to 7.2, which allows for a gentler wave formation compared to higher pH alkaline waves. This balanced pH ensures the hair cuticle opens sufficiently for the waving solution to penetrate, while minimizing damage, making the curling process more efficient.

Additionally, acid balanced waves are known for their ability to create a firmer curl due to the unique formulation of the waving solution that promotes enhanced bonding of the hair's disulfide bonds, resulting in more defined curls. This quality is especially beneficial for clients seeking a longer-lasting hairstyle that holds its shape well. The formulation also enables a quicker processing time than true acid waves, allowing stylists to achieve desired results efficiently.

Other types of waves mentioned, such as cold waves and alkaline waves, have different pH levels and properties that lead to varying results in terms of curl firmness and processing speed. Cold waves tend to use an endothermic process, which generally takes longer compared to acid balanced waves. Alkaline waves, while producing strong curls as well, often require more
