It all comes down to the material and how you take care of the nails. Mostly, nails are crafted from polymethyl methacrylate acrylic, along with other substances. This makes their texture very similar to real nails; however, they are much sturdy. The material is also good to stick and easy to handle. However, with good hygiene, you should not face any issues. Also, if you can, then do for the removable ones, instead of the long-lasting nails, if you don‘t find the time to care for them. Allergies are something a lot of women complain about when it comes to artificial nails, but this all depends on several factors. If it‘s worse, then you should stick to real nails, and manicure them often, so they look presentable. For brittle nails, it‘s best to check with a doctor for any deficiencies.
