Nail conditioning

Ingredients with nail conditioning function help maintain the nail plate in good condition: they reduce the feeling of dryness, make the surface smoother and more well-groomed, can reduce brittleness and delamination, and improve the appearance of dull and damaged nails. In formulas, such substances work primarily with the nail plate and cuticle area, and not with hair or scalp. According to the European CosIng database, this is a separate cosmetic function for substances that help keep nails in good condition. (cosingchecker.com)

Hydrolyzed Keratin — hydrolyzed keratin is often used in this role. It belongs to the conditioning components for nails and is included in the products for weakened, soft and prone to damage nails. Panthenol is also a typical example: it is known as a moisturizing and softening component, and studies show that it is able to penetrate into the nail better from special products than from a simple aqueous medium, which makes it useful in the care of dry and brittle nails.

Such ingredients are usually added to serums, oils, bases, and restorative nail coatings, where they improve not so much the texture of the product itself as the condition and appearance of the nails after application. It is important to understand that this is cosmetic care, not the treatment of nail diseases: the task of such components is to make nails more elastic, less dry and visually more even. Examples of ready-made products with this formula logic show that hydrolyzed keratin and panthenol are often used together to care for a weakened nail plate. (trindstore.com)
