Two Science-Backed Products That Can Fix Brittle Nails in Weeks
Brittle nails affect more than one in four women, often caused by dehydration, nail-biting, or daily chores. Despite being made of the same protein as the skin’s outer layer, nails frequently go untreated. This neglect can lead to splitting and breakage over time.
Nail strengtheners aim to tackle these issues by adding a protective layer. Many contain nutrients like calcium, magnesium, and vitamins A, C, and E. These ingredients nourish the nail, helping it grow thicker and more resilient with regular use.
Two products have shown promising results in tests. Manucurist Perfektionierendes Konzentrat uses pistachio extract, castor oil, and vitamin E to repair damage. In a 21-day dermatological study with 24 participants, it improved nail strength and repair by 83-88%. Meanwhile, Poderm Gelbe, beschädigte Nägel Serum targets yellow, weakened nails with phyto-keratin. After 28 days of testing on 20 people, it boosted nail strength by 23% and enhanced their appearance.
No recent changes to European regulations on nail strengtheners have been reported in available sources.
Using nail strengtheners consistently can lead to stronger, healthier nails. Products with proven ingredients have demonstrated measurable improvements in clinical tests. For those struggling with brittleness, these treatments offer a practical way to restore nail condition over time.
