Here are some details about permanent hair straightening creams, including their ingredients, positive and negative aspects, and materials used:
Ingredients and Materials:
-
Glyoxylic Acid: This is the active ingredient responsible for permanent hair straightening. Its concentration in the product should be high for effective results.
-
Glyoxyloyl Carbocysteine and Glyoxyloyl Keratin Amino Acids: These ingredients are also involved in the hair straightening process.
-
PEGs and "-eth" Ingredients: Some permanent hair straightening treatments contain ethoxylated ingredients, such as PEGs and Ceteareth-7. These ingredients are made through a process called ethoxylation, which can result in the presence of carcinogenic 1,4-dioxane in the product.
-
Butylphenyl Methylpropional: This is another ingredient to watch out for, as it can cause skin irritation.
-
Triethanolamine: This ingredient can be harmful if it comes into contact with the eyes, skin, or respiratory system.
-
Fragrance: Fragrances in hair straightening products can be a source of hidden ingredients, including potentially harmful ones.
-
Methylchloroisothiazolinone and Methylisothiazolinone: These ingredients are preservatives that can cause skin allergies.
-
Collagen, Glycerin, and Plant Extracts: Some hair straightening creams, like the Silk and Gloss Straightening Protein Correcting Hair Straightener, use these ingredients for their mild and safe properties.
-
Alkanoic Acids: A formulation for hair straightening may include alkanoic acids and a diluent. This type of formulation is acidic and does not use an effective amount of an alkaline hair-straightening agent.
Positive Aspects:
-
Exceptionally Gentle Formula: Some hair straightening creams, like the Herbishh Instant Hair Straightener Cream, are formulated with gentle and safe ingredients.
-
Mild and Safe: The Silk and Gloss Hair Straightening Cream is advertised as being made of collagen, glycerin, plant extract, and other active nourishing ingredients.
Negative Aspects:
-
Ethoxylated Ingredients: Hair straightening treatments that contain PEGs, Polysorbates, and other ethoxylated ingredients may have traces of carcinogenic 1,4-dioxane due to the ethoxylation process.
-
Skin Irritants: Some ingredients, such as Butylphenyl Methylpropional and Triethanolamine, can cause skin irritation.
-
Preservatives: Methylchloroisothiazolinone and Methylisothiazolinone are preservatives that can cause skin allergies.
-
Formaldehyde: Some hair straightening products may contain formaldehyde, which is a known carcinogen. Be cautious when choosing a hair straightening cream and look for products that are labeled as formaldehyde-free.
