In hairdressing, what does "PR" stand for?

In the context of hairdressing, "PR" stands for Permanent Relaxer. A Permanent Relaxer is a chemical product used to straighten curly or wavy hair by breaking the bonds in the hair structure. This process alters the hair's natural texture, making it smoother and easier to manage. A Permanent Relaxer is typically used in professional settings and requires proper application techniques to achieve the desired results safely.

Understanding the significance of a Permanent Relaxer is essential for hairdressers as it involves knowledge of hair chemistry, appropriate products, and the techniques for successful application. Misapplication can lead to damage, so it is critical to have training and a clear understanding of the product's capabilities and limitations.
