What type of nail trim should be avoided for clients with onychophagy?

Clients with onychophagy, or chronic nail biting, often have irregularly shaped and sometimes damaged nails. A straight trim, which results in sharp edges, may exacerbate their condition by increasing the risk of snagging or breaking the nails, leading to further trauma or discomfort. It can also create an unappealing look since the nails are typically not uniform due to the biting habit.

In contrast, a rounded trim helps to soften the edges of the nails, making them less prone to snagging. This type of trim is more forgiving for damaged nail beds and promotes a healthier nail condition over time. It encourages clients to maintain their nails and can help in transitioning away from the habit of nail biting, as it presents a more aesthetically pleasing appearance. Thus, it's important to avoid straight trims for onychophagy clients to prevent exacerbating any issues with their nails.
