What should be done before applying a perm solution?

Before applying a perm solution, washing and conditioning the hair is essential for several reasons. Clean hair allows for better penetration of the perm solution, ensuring that the waves or curls will set properly. Any build-up of products like oils, gels, or sprays can hinder the chemical reaction necessary for the perm to take effect. Conditioning the hair also helps to maintain its health and manageability, reducing the risk of damage during the perming process.

While cutting the hair to the desired length, applying a relaxing treatment, or ensuring the hair is completely dry might have their own specific purposes in hair care or styling, they are not the immediate steps required before a perm. Washing and conditioning prepares the hair to effectively respond to the chemicals used in the perm solution, making it the most critical preliminary step in the process.
