Take a look at the ranking for the best cosmetics for brittle nails:
Touch Nail and Cuticle Conditioner is the perfect support for those struggling with brittle nails. It contains natural oils such as castor, argan and abyssinian oils as well as vitamins A, E, B3, natural phyllosterols and squalene, which effectively moisturise, regenerate and strengthen the nails. Thanks to these ingredients, the Touch conditioner not only nourishes and regenerates, but also prevents nails from splitting and breaking. Its regular use allows a rapid improvement in the condition of the nails, which become stronger, more flexible and less susceptible to damage. The vitamins contained in the conditioner protect the nails from negative external influences, while squalene and phyllosterols ensure proper hydration and protection against moisture loss. Touch conditioner is ideal for those looking for an effective solution to brittle nails and dry cuticles, providing them with comprehensive and gentle care.
Pirolam nail conditioner is a popular solution for those struggling with brittle and fragile nails. The product can be used not only as a strengthening treatment, but also as a base coat, protecting nails from discolouration and increasing the durability of the manicure. The formulation contains ceramides, which are key lipids that support the structure of the nail plate, preventing it from drying and external damage, as well as aiding its regeneration. When using Pirolam conditioner, it is recommended to avoid other preparations with similar effects. The conditioner comes in the form of a slightly milky varnish and is not the most comfortable to apply. It may also chip after a few days, especially with frequent contact with water, requiring more frequent application than the manufacturer's suggested every four days.
The Regenerum conditioner formula has been specially formulated to support the recovery of damaged, weakened and brittle nails. It has a strengthening effect on the nail plate, protecting it from mechanical damage and further securing it thanks to the adhesive resin contained in the product. Ingredients such as proteins and minerals regenerate and stimulate nail growth, reducing brittleness. Algae extracts intensively moisturise and counteract oxidation, which is crucial for split nails. The serum is recommended to be applied once a week, but due to the form of the polish, which chips after a few days, it needs to be renewed more often, every 2-3 days, to maintain the aesthetic appearance of the manicure. In addition, the intense chemical smell of the product can be bothersome during application.
Colostrum Nail Booster from Clarena is a conditioner for the regeneration of split nails. Our testers appreciated the product's effect on accelerating growth and strengthening brittle nails, but applying the conditioner required special preparation: nails had to be cut short and the product had to be applied at least once a day, waiting until it was completely absorbed. This posed a challenge for those who appreciate quick treatments, especially as the conditioner absorbed slowly. Strengthening and faster growth of brittle nails was only apparent with regular use. The testers did not notice a significant improvement in the appearance of their cuticles. Advantages of the product were its efficiency and the ease of squeezing to the last drop from the soft tube.
Miss Sporty's 5-in-1 conditioner is designed to strengthen, moisturise, smooth and accelerate the growth of brittle nails. However, according to our testers, the product only partially fulfils its promises. The strengthening effects were rated as moderate, and the promised acceleration of nail growth was not noticeable for most users. Nevertheless, thanks to ingredients such as olive extract, avocado and vitamins A, C and E, the nail plate received a noticeable shine and improved hydration. Users appreciated the attractive price of the product, but expressed dissatisfaction with regard to its durability and the difficulty in getting the cosmetic to last.
