What is Hydrolyzed Hair Keratin?
Hydrolyzed hair keratin is a valuable component in beauty products, particularly in hair and skin care formulations. This ingredient is created through a process called hydrolysis, which breaks down natural keratin proteins into smaller molecules. These proteins typically come from sources such as wool or other animal hair.
The breakdown of keratin makes it easier for hair and skin to absorb the beneficial properties of this ingredient. When applied, these smaller protein molecules can penetrate the hair shaft or skin surface more effectively. This results in the filling of gaps in the hair’s cuticle or the strengthening of the skin’s protective barrier.
Hydrolyzed hair keratin functions as a skin conditioning and hair conditioning agent. As a skin conditioning agent, it helps to improve the appearance and feel of skin. The small keratin molecules can penetrate the upper layers of the epidermis, where they help to retain moisture and support the skin’s natural barrier function. This can lead to improved skin texture, increased hydration, and a smoother overall appearance.
In its role as a hair conditioning agent, hydrolyzed hair keratin works by adsorbing onto the hair surface and penetrating the cortex. This process helps to repair damaged areas of the hair shaft, improve hair elasticity, and enhance its overall strength. The keratin molecules can fill in gaps and weak spots along the hair shaft, helping to smooth the cuticle and reduce frizz. This conditioning effect results in hair that is softer, more manageable, and less prone to breakage and split ends.
Who Can Use Hydrolyzed Hair Keratin?
When it comes to skin types, hydrolyzed hair keratin is pretty inclusive. It’s generally suitable for all skin types, including sensitive skin. However, if you have a specific allergy to proteins or keratin, you might want to steer clear or consult with a dermatologist first.
Now, for the vegans and vegetarians out there, it’s important to note that hydrolyzed hair keratin typically comes from animal sources. This means it might not align with vegan or vegetarian lifestyles. If you’re looking for a plant-based alternative, there are synthetic or plant-derived proteins that might serve a similar purpose.
As for expecting or breastfeeding moms, there’s generally no restriction on using products containing hydrolyzed hair keratin. However, it’s always a good idea to check with your healthcare provider if you have concerns about any personal care ingredients during pregnancy or while nursing.

Comedogenic Rating
Comedogenicity refers to the potential of cosmetic ingredients to cause comedones, which are skin pores or hair follicles that become clogged with oil and can lead to acne. Ingredients are rated on a scale from 0 to 5, with 0 being non-comedogenic (will not clog pores) and 5 being highly comedogenic (very likely to clog pores).
Hydrolyzed Hair Keratin has a comedogenic rating of 0. This rating is assigned because it is primarily a protein derivative that does not contribute to the clogging of pores. Instead, it focuses on conditioning and strengthening hair and skin.
Given its non-comedogenic rating, Hydrolyzed Hair Keratin is generally suitable for those who are prone to acne or breakouts, as it does not block pores or contribute to the formation of acne.
Conclusion
Hydrolyzed Hair Keratin primarily functions as a hair and skin conditioning agent. It helps to improve moisture retention and elasticity, making it beneficial for both hair and skin health. While not as widely discussed as some other ingredients, Hydrolyzed Hair Keratin holds a niche but significant role in cosmetic formulations, similar to other protein-based ingredients that aim to repair and protect.
The popularity of Hydrolyzed Hair Keratin may not be as high as more mainstream ingredients, but it remains a valid choice for specific formulations aimed at strengthening and conditioning. Its use is well-regarded among products designed for damaged hair or sensitive skin.
Overall, Hydrolyzed Hair Keratin is considered safe for use in cosmetics. Its benefits in improving hair and skin texture, combined with its non-comedogenic properties, make it a reliable choice for formulators and consumers alike.
