If your nail polish has become too thick, you can thin it out using specific techniques to restore its original consistency. This ensures smooth application and extends the life of your favorite polish. Here’s how you can effectively thin out mixed nail polish.
What Causes Nail Polish to Thicken?
Nail polish thickens due to evaporation of its solvents, which can happen if the bottle is not tightly sealed or if it is exposed to air for extended periods. This results in a gooey texture that makes application difficult and uneven.
How to Thin Out Thick Nail Polish?
To thin out thick nail polish, you can use a nail polish thinner. This product is specifically designed to restore the polish’s original consistency without altering its color or finish. Here’s a step-by-step guide:
-
Purchase a Nail Polish Thinner: Available at beauty supply stores, a nail polish thinner contains the same solvents found in nail polish, making it ideal for restoring consistency.
-
Add a Few Drops: Start by adding 2-3 drops of thinner to the nail polish bottle. It’s important not to overdo it, as too much thinner can make the polish too runny.
-
Shake the Bottle: After adding the thinner, securely close the bottle and shake it well to mix the thinner with the polish. This helps in evenly distributing the thinner throughout the polish.
-
Test the Consistency: Open the bottle and check the consistency. If the polish is still too thick, add one or two more drops of thinner and shake again.
-
Repeat as Necessary: Continue adding thinner in small increments until the polish reaches the desired consistency.
Can You Use Acetone to Thin Nail Polish?
While some might consider using acetone or nail polish remover to thin out polish, it is not recommended. Acetone can break down the polish’s formula, leading to separation and uneven application. It may also alter the color and finish of the polish.
Tips for Preventing Nail Polish from Thickening
To keep your nail polish in good condition and prevent it from thickening, follow these tips:
- Store Properly: Keep nail polish bottles in a cool, dark place away from direct sunlight and heat, which can cause evaporation.
- Seal Tightly: Always ensure the bottle cap is tightly closed after each use to prevent air exposure.
- Clean the Neck: Regularly clean the neck of the bottle with a cotton swab and acetone to remove dried polish, ensuring a tight seal.
