Hair Structure & Chemical Processing
The Science of Lash Lifting
Hair Structure • Chemical Bonds • pH Science • Porosity • Thickness • Growth Cycle • Colour Changes • Ingredients
A lash lift isn’t just a beauty treatment; it’s a controlled chemical process that temporarily reshapes the natural lashes by breaking and reforming internal bonds within each hair shaft. To perform it safely and achieve consistent, high-quality results, it’s important to understand:
- How lash hair is structured
- What happens during the lifting and tinting process
- How factors like pH, porosity, thickness, and growth cycle affect your results
This scientific knowledge helps you protect lash health and deliver long-lasting, flawless lifts.
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 lash lift 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 lashes healthy.
By mastering lash science, you’ll deliver safe, consistent, and beautifully lifted results every single time.
