Final answer:
A scalp treatment can be performed before hair treatments such as chemical straightening, perms, or coloring, to prepare and protect the hair and scalp. Specialty shampoos are used in scalp treatments to cater to individual hair care needs and to ensure the hair responds well to the chemical treatments.
Step-by-step explanation:
A scalp treatment can be performed before a variety of different hair treatments. The main purpose is to prepare the scalp and hair for further styling or treatment processes, such as chemical straightening, perms, or coloring. Specialty shampoos are available to cater to individual needs, including those with sensitivity to certain ingredients like gluten, those with colored hair, or those with specific conditions like dandruff. These shampoos can be used as part of the scalp treatment to ensure the hair is in the best possible condition for the subsequent procedure.
When it comes to perms, either thermal or chemical methods can be used. Prior to applying these treatments, a scalp treatment can help protect the scalp and ensure that the hair is adequately prepped to receive the chemicals. This is essential to avoid potential damage and to achieve the best results whether the hair is being curled or straightened. Similarly, those intending to color their hair can benefit from a scalp treatment to ensure that the color is more vibrant and long-lasting.
