The main enjoyment with a salon is that you can pick your best color nail polish from a wide range and ask to apply them on your nail to your nail tech. But the problem is that all those bottles are already shared with many other users and there has a risk factor available. If someone with fungus infection used this bottle, then the next person could become infected. To escape from contracting fungal bacteria, you can purchase your own nail polish bottle. Bring your polish bottle to the salon and ask the expert to apply it only.
