Adverse Effects of Keratin on the Scalp
The harmful effects of keratin treatments primarily stem from the presence of formaldehyde in their formulations. This substance can trigger skin allergies upon contact and has been linked to skin cancer with prolonged exposure. Additionally, inhaling formaldehyde can lead to respiratory issues, given that it is categorized as a potent harmful gas. Although numerous salons offer formaldehyde-free keratin treatments, they often fail to list all ingredient components transparently, or they may include disguised ingredients that are not clearly disclosed. Even products marketed as formaldehyde-free can release this compound into the air when heat is applied through hair-styling tools, indicating that formaldehyde is often hidden within the ingredients list.
General Risks Associated with Keratin Treatments
Experts in cosmetology have expressed concerns regarding the dangers of formaldehyde, particularly its potential to cause respiratory complications and nosebleeds due to smoke generated during the application of keratin to hair. Continued use of formaldehyde-based products may lead to significant respiratory injuries. Research has revealed that the levels of formaldehyde in some products exceed national safety standards by five times. Consequently, it is strongly recommended that pregnant women, individuals with respiratory issues, or those allergic to formaldehyde avoid these treatments altogether.
Safety Standards for Keratin Application
A set of safety standards has been established for the usage of keratin and similar products containing defined levels of formaldehyde. Salon and beauty center owners are expected to adhere to these guidelines diligently. Recommended practices include ensuring proper ventilation in the treatment area, conducting air quality tests before application, and providing full protective gear to hair stylists and beauticians. However, these safety measures are often applicable only to professionals and do not encompass clients receiving the treatment. Many keratin products claim to be composed of natural ingredients, such as keratin and berry extracts; however, because they are frequently applied using heat, they typically still contain formaldehyde.
From the client’s perspective, it is essential to be well-informed about the contents of keratin treatments and to inquire with the hairstylist about the specific product and brand being used, including the concentration of formaldehyde. A prudent option is to seek out a stylist who utilizes “Fume Iron” technology, as this method evenly distributes heat while effectively capturing and eliminating harmful fumes, thereby protecting both the stylist and the client.
