What effect do harsh chemicals in nail products typically have on nails?

Harsh chemicals found in many nail products can result in damage to the nails due to their abrasive nature and potential to disrupt the natural moisture balance. Ingredients such as formaldehyde, acetone, and certain artificial dyes can weaken the structural integrity of the nails, leading to brittleness, splitting, or peeling. Over time, exposure to these chemicals can also compromise the overall health of the nail bed and surrounding skin, potentially causing irritation or allergic reactions.

In contrast, nourishing and growth-promoting effects are generally associated with products that contain vitamins or moisturizing ingredients, which are not typically categorized as harsh chemicals. Likewise, while some products may aim to enhance flexibility, this effect is generally more related to specially formulated treatments rather than the harmful chemicals prevalent in many nail products.
