Short answer is yes, but for a short amount of time.
If you use adhesive tabs to fix the nails, don't let your fingers come into contact with water for at least 2-3 hours after the application.
However, it should be noted that it is not completely waterproof, so do not touch it with water immediately after sticking it, and usually try to minimize the contact of nails with adhesive tabs with hot water. If you want to wash your hands, you can wash it for a short time. But don't soak the adhesive tab in water for a long time, which will accelerate the shedding of the press-on nails. Adhesive tab is a relatively safe nail material. It uses animal glue, which is harmless to the nails. However, it is necessary to protect the nails in your daily life, such as reducing scratches on the nails and reducing its contact with the nails, avoid moisture.
If the above requirements can be met, your nails can generally be maintained for three to five days. The maintenance time cannot be considered too long, but the specific time varies from person to person. There may be some people who have not been exposed to water, but the press-on nails fall off quickly. If it falls off, it may be caused by the incorrect way of wearing it. It is best to remove the nail piece and choose the correct way to wear it.
