What hair characteristics can influence the choice of perm technique?

The choice of perm technique is heavily influenced by hair texture, density, and porosity because these characteristics directly affect how the hair will react to the perming solution and the resulting style.

Hair texture refers to the thickness of the individual strands and the overall wave or curl pattern, which will determine the size and type of curl that can be achieved. For instance, finer hair may need a gentler technique, while coarser hair might handle a stronger solution.

Density relates to the number of hair strands on the scalp. A person with high density may require more product and a different wrapping technique to ensure even processing, while those with low density may have different considerations to avoid over-processing.

Porosity indicates how well the hair can absorb moisture and products. Hair that is more porous tends to take to perm solutions more quickly, which might necessitate a less intense processing time or a different application method to avoid damage.

Understanding these attributes allows a stylist to tailor the perm process to achieve the desired result while maintaining the health and integrity of the hair.
