Changes in the nails, such as unusual color or shape (like spoon-shaped nails indicating iron deficiency or white nails potentially signaling diabetes or heart issues), can be early signs of systemic diseases. Observing nail health can provide valuable clues for early diagnosis and intervention. Many standard nail enhancements, like gels, acrylics, and dips, can damage the nail plate and surrounding skin. In particular, the removal process of soak-off gels has been scientifically proven to thin and weaken the nail plate, making it more prone to brittleness and breakage. Potential risks are associated with UV lamps used in gel manicures. Switch to a precision glass nail file for smoother, healthier nail edges and reduced breakage. Nails don't breathe, but good blood flow is crucial for their health. Therefore, maintaining good peripheral circulation through cardiovascular activity or even hand massage is vital for healthy nail growth and preventing issues like brittleness and peeling, especially as we age and tend to have poorer circulation.The cuticle is a vital protective barrier for the nail and should not be removed. It acts as a natural seal, protecting the nail matrix (the nail's growth center) from water, moisture, and pathogens. Disrupting the cuticle can lead to nail abnormalities like patches, surface irregularities, bumps, and even separation. Liquid cuticle removers essentially destroy the cuticle, just like cutting it.
