The Science of Brow Lamination

Hair Structure • Chemical Bonds • pH Science • Porosity • Thickness • Growth Cycle • Colour Changes • Ingredients

Brow lamination is not just a beauty treatment: it’s a chemical process that alters the internal structure of each brow hair. To perform it safely and deliver the best results, you need to understand:

• How brow hair is built
• What happens to it during lamination
• How factors like pH, porosity, thickness, and growth cycle influence the outcome
  

This knowledge is what separates a brow artist from someone who just applies products.

At this stage: You only need to understand how these solutions interact with the hair structure and bonds. The exact ingredients can vary between brands and formulas, which affects how strong, gentle, or nourishing the products are.

In the next section, we’ll take a closer look at the active ingredients inside your lamination kit: comparing options like thioglycolic acid vs. cysteamine, hydrogen peroxide vs. sodium bromate, and the role of keratin, proteins, and oils. This will help you choose the right formulas for each client while keeping their brows healthy.

Mastering these basics allows you to adjust every treatment to your client’s brows - achieving safe, consistent, and healthy results.
