When applied and removed properly, gel polish does not tend to damage the nails. However, if incorrect application or removal methods are used, it can cause harm to the nails. Therefore, it is important to work with a professional nail technician for gel polish application.

When proper application and removal techniques are used, gel polish can actually provide protection and make the nails stronger. Gel polish can protect the nail surface and reduce cracking, breaking, and chipping.

However, the following situations can damage or weaken the nails:

1. Incorrect removal: It is important to be careful when removing gel polish. Incorrect removal methods that force the nail surface, damage the nail bed, or scrape off the hardened polish can harm the nails.

2. Frequent application of gel polish: Constantly applying and then removing gel polish can disrupt the natural balance of the nails. This can lead to weakening and increased brittleness.

3. Prolonged use: Gel polish can stay on the nails for a long time, but extending this duration excessively can damage the nails. Keeping gel polish on for too long can dry out and weaken the nail surface.

4. Unprofessional application: Gel polish should be applied using the correct techniques and the right products. Unprofessional application can damage the nails and increase the risk of infection.

To maintain nail health, it is important to have gel polish applied by an experienced nail technician and to regularly allow time for your nails to rest and be nourished.
