It is unclear from the question whether you are looking for information on a specific nail shop or just general information on nail products. However, based on the search results, here is some general information on nail products, including their ingredients and potential positive and negative effects:

Ingredients:

• Nail products may contain potentially harmful ingredients, such as toluene, formaldehyde, dibutyl phthalate, ethyl methacrylate (EMA), and methyl methacrylate (MMA) .
• Artificial nails are composed primarily of acrylic polymers, which are made by reacting together acrylic monomers, such as EMA monomer, with acrylic polymers, such as polymethylmethacrylate. When the reaction is completed, traces of the monomer are likely to remain in the polymer.

Positive effects:

• Nail products can enhance the appearance of nails, making them look more polished and attractive.

Negative effects:

• Nail products can expose nail salon workers to chemicals, which can affect their health.
• Some nail products contain potentially harmful ingredients, but are allowed on the market because they are safe when used as directed.
• Workplace exposure to chemicals in nail products can pose a real threat to nail technicians.
• Some ingredients in nail products can cause allergies, asthma, dermatitis, and other health problems.
• Nail products can be hazardous when used improperly or in poorly ventilated spaces.
• Nail products can be harmful if ingested accidentally.

It is important to use nail products safely, following labeled directions and paying attention to any warning statements. Nail products for both home and salon use are regulated by the Food and Drug Administration (FDA), and by law, nail products sold in the United States must be safe for consumers when used according to directions on the label, or in the usual or customary way. If you have concerns about the safety of a particular nail product, you can check the EWG Skin Deep® Cosmetics Database to evaluate its ingredients.
