Here's what the term likely refers to:
* Keratin in Hair Dye: Keratin is a protein naturally found in hair. Some hair dyes may include keratin derivatives or hydrolyzed keratin in their formulas. This is often marketed as a benefit because:
* It can help with hair conditioning: Keratin can smooth the hair cuticle, improving shine and manageability.
* It can potentially strengthen hair: Keratin can help repair damaged hair fibers to some extent.
* "Pro" in Hair Dye: This is a more general term that suggests a product is professional-grade or high-quality. It might indicate that the dye is designed for salon use, has higher pigment concentration, or contains more advanced ingredients.
However, it's important to note:
* Not all hair dyes with keratin are created equal: The quality and quantity of keratin used vary widely between brands.
* Keratin's effect on hair dye is debatable: Some studies suggest that keratin can improve hair dye results, but others show minimal or no impact.
* The term "pro keratin" is not regulated: It's best to research the specific brand and product to understand what exactly "pro keratin" means in that context.
To find out more about a specific product:
* Read the product label: Look for the ingredient list and claims about keratin.
* Check the brand's website: They may have more information about the product's formula and benefits.
* Ask a hairdresser: They can offer expert advice on hair dyes and their ingredients.
Remember, the best hair dye for you depends on your hair type, desired color, and individual needs. Don't rely solely on marketing terms, but do your research to make an informed decision.
