Hair Structure & pH Scale

Color Theory Review • Lesson Two*

Have you ever tested the pH of the products you have in the salon? Maybe it’s about time to. I’m going to encourage you to become an informed consumer about all the products you use on your clients. Because only then are you able to make your client’s hair react the way you need it to, consistently, time after time, regardless of the brand of color you use.

We manipulate the pH of the hair to get it to perform the way we want it to. Because of that you need to have a strong understanding in what the pH scale is, what it measures, and how that relates to the structure of the hair.

A big part of this lesson is also devoted to exploring the advantages of coloring damp hair instead of dry hair. Plus, we will cover the best order-of-operations to tone your clients efficiently.

Here’s what you’ll learn:

  • Defining important parts of the hair structure
  • What role do the cuticle & cortex play in haircolor
  • Why the pH Scale is important to us
  • Why I don't shampoo before toner
  • Why haircolor should be applied to damp hair
  • Can hair actually "get used" to a shampoo?

After purchasing this lesson, my biggest piece of advice is to watch the video first, and then watch it again while answering the workbook questions. It's important that you actually understand your answers so you can remember this information while working behind the chair.

This Single Lesson Purchase Includes 1 video lesson (31 minutes) and 1 workbook.
