In the professional world of brow lamination, many factors contribute to a perfect and long-lasting result. One often underestimated yet crucial factor is the pH level of the products used. At MONLIS School in Munich – the leading institution for manicure, pedicure, and brow styling education – students learn how important proper pH balance is for maintaining hair health and achieving optimal results.
What is pH and Why Does it Matter?
The pH level indicates how acidic or alkaline a substance is. The scale ranges from 0 to 14, with 7 considered neutral. Values below 7 are acidic, and those above are alkaline. In cosmetics, the pH level directly influences how a product interacts with the skin, hair, and particularly the structure of the brow hairs.
Hair Structure and Natural pH
Eyebrow hairs, like scalp hairs, are made of keratin. This protein is sensitive to external influences, especially to highly alkaline or acidic substances. The natural pH of hair is between 4.5 and 5.5, slightly acidic. If products significantly alter this balance, the hair can swell, weaken, or lose elasticity.
Typical pH Ranges in Lamination Products
Brow lamination involves at least two main products:
-
Lifting lotion – Opens the hair cuticle to allow reshaping. It usually has an alkaline pH of around 8–9.
-
Fixing lotion – Closes the cuticle and sets the hair in its new shape. It typically has an acidic pH between 2 and 4.
Managing the pH levels precisely is essential for a safe and effective reshaping process.
Risks of Incorrect pH Levels
A product that is too alkaline can damage the hair’s structure. If the cuticle opens too much, it leads to protein and moisture loss. The result: porous, dry, brittle brow hairs that are difficult to shape. A product that is too acidic may result in poor fixation, reducing the treatment’s durability.
Professional pH Training at MONLIS School
In our brow lamination courses, we teach not just techniques but also the chemical foundations. Our students learn to:
-
Read and interpret product pH values,
-
Follow a safe product application sequence,
-
Restore hair balance with pH-neutralizing products,
-
Avoid skin irritation caused by improper pH use.
Impact on the Final Result
An ideal pH balance ensures:
-
Smooth and even hair structure,
-
Shiny and healthy-looking brows,
-
Long-lasting hold without breakage,
-
Minimal risk of skin reactions.
At MONLIS School, students gain hands-on experience with real products and situations to apply pH knowledge confidently in their future careers.
Aftercare: Using pH-Balancing Products
After lamination, aftercare is just as important. pH-neutral serums or oils can help restore the hair’s natural state. We recommend avoiding harsh cleansers and opting for hydrating and soothing post-treatment care.
Selecting and correctly applying pH-appropriate products is essential for high-quality brow lamination. MONLIS School in Munich teaches this knowledge thoroughly and practically—ensuring safe treatments, healthy brows, and excellent outcomes.
