Final answer:
Chemical relaxing and excessive heat styling should be avoided prior to a permanent wave as they can weaken the hair and make it more susceptible to damage. Harsh chemical treatments like bleaching or coloring should also be avoided to maintain the hair's integrity. Consult a professional stylist for personalized advice.
Step-by-step explanation:
Prior to a permanent wave, certain reconditioning treatments should be avoided to prevent damage to the hair. One treatment to avoid is chemical relaxing, which involves the use of strong chemicals to straighten curly or wavy hair. This treatment can weaken the disulfide bonds in the hair, making it more prone to damage during the permanent wave process. Another treatment to avoid is excessive heat styling, such as using flat irons or curling irons, as it can also weaken the hair and make it less resistant to the chemical processes involved in a permanent wave.
Additionally, any treatments that involve harsh chemicals, such as hair bleaching or coloring, should be avoided directly before a permanent wave. These treatments can alter the porosity of the hair and make it more susceptible to damage during the permanent wave process.
Overall, it is important to prioritize the health and strength of the hair before undergoing a permanent wave, and to consult with a professional stylist for personalized advice based on the individual's hair type and condition.
