Protein Straightening Claims to Nourish Hair, But Ingredients Tell a DifferentStory
Beijing, China – A new hair straightening method, dubbed protein straightening, has been gaining popularity in salons across China. Promising smooth, silky hair without damage, the treatment has attracted many customers. However, arecent investigation by a journalist from a leading Chinese media outlet has revealed that the claims of nourishment may be misleading.
The journalist, who has worked for prominent newsorganizations like Xinhua News Agency, People’s Daily, CCTV, Wall Street Journal, and New York Times, decided to investigate the protein straightening treatment firsthand. They underwent the procedure at a local salon and obtained the ingredient list of theproducts used.
The analysis of the ingredients revealed a concerning truth: the treatment relies on the same chemical processes as traditional hair straightening, utilizing harsh chemicals that can cause significant damage to the hair.
The protein straightening process typicallyinvolves two steps, using two different solutions labeled A and B. Solution A, applied first, contains a combination of water, ammonium hydroxide (an alkali agent that opens the hair cuticles), and thioglycolic acid (a reducing agent that breaks down disulfide bonds in the hair).
The disulfide bonds are crucialfor hair’s structure and flexibility. Breaking them allows the hair to be reshaped. However, this process also weakens the hair, making it more prone to breakage and damage.
The second solution, B, contains water, sodium bromate (an oxidizing agent that re-forms the disulfide bonds, fixing thehair in its new shape), and glycerin. Glycerin, a humectant, is known for its moisturizing properties, which is likely the source of the nourishing claim. However, this temporary effect is superficial and does not negate the damage caused by the initial chemical treatment.
The journalist also discovered that someprotein straightening products contain formaldehyde or glycolic acid, both of which are known to have harmful effects on human health. Formaldehyde, a known carcinogen, can cause respiratory problems and skin irritation, while glycolic acid can lead to skin burns and allergic reactions.
While the journalist’s investigation focused on the protein straightening method in China, it highlights a broader issue in the beauty industry. Many hair treatments, including traditional perms and dyes, rely on chemicals that can damage the hair and pose health risks.
The journalist’s findings serve as a reminder that consumers should be cautious about claims made by beauty salons andmanufacturers. It is crucial to research the ingredients used in hair treatments and understand their potential risks.
Here are some key takeaways from the investigation:
- Protein straightening is not a new, revolutionary treatment. It relies on the same chemical processes as traditional hair straightening, utilizing harsh chemicals that can damagethe hair.
- The claim of nourishment is misleading. While the treatment may temporarily make the hair feel smoother due to the presence of glycerin, it does not address the underlying damage caused by the chemical process.
- Some protein straightening products contain harmful chemicals like formaldehyde and glycolic acid, which can pose health risks.
The journalist’s investigation serves as a valuable reminder that consumers should be informed and critical when it comes to beauty treatments. Choosing healthy alternatives and prioritizing hair care are essential for maintaining healthy, beautiful hair.
