Certain chemical agents can break down or weaken keratin. While keratin is a strong protein, it's not indestructible. Specific treatments target keratin to achieve desired cosmetic or therapeutic effects.
Chemical Agents that Affect Keratin
-
Salicylic Acid: This is a common ingredient in many skincare products. It effectively breaks down keratin, softening thickened skin and reducing the build-up of dead cells. This action is useful in treating conditions like hyperkeratosis, where excessive keratin buildup occurs. [Source: News-Medical.net, The Naked Chemist]

Urea-based Agents: These agents increase water content in the skin, further softening and aiding in the breakdown of keratin, though less effectively than salicylic acid. [Source: News-Medical.net]

Exfoliation and Moisturizing: While not a direct "killer" of keratin, regular exfoliation and moisturizing help to remove built-up keratin and prevent excessive accumulation. This approach is particularly useful in managing keratin plugs. [Source: Healthline]
Keratin Treatments: A Different Perspective
It's important to note that "killing" keratin isn't always the goal. Keratin treatments for hair aim to temporarily alter its structure for cosmetic purposes like smoothing and reducing frizz. These treatments typically use heat and chemical processes to reshape the hair's keratin bonds. They do not destroy the keratin itself, but rather modify its arrangement.

It's crucial to understand that the context is key. While salicylic acid and urea weaken keratin for therapeutic purposes, keratin treatments for hair work differently, aiming for a temporary structural change rather than destruction.
