Do You Use Nail Primer Or Dehydrator First

Do You Use Nail Primer or Dehydrator First? Here’s What You Need to Know

Nail primers and dehydrators are both essential products that help ensure that your nail polish lasts longer without chipping or fading. However, many people are unsure of the order in which to use them. Some wonder whether to reach for the nail primer first, while others believe the dehydrator should come first in the process.

In this article, we’ll talk about the purpose of each product, how they work, and which one should you use first.

What is a Nail Primer?

A nail primer is a product used before applying nail polish to improve the adhesion of the polish to the nail plate. A good nail primer serves as a base layer that helps to protect the nail from staining and chipping. Nail primers are typically formulated with ingredients that not only help polish adhere to the nail surface but also protect it from damage.

Nail primers often contain ingredients such as resins, waxes, or polymers that help to create a stronger bond between the nail polish and the nail bed. These ingredients help to prevent the polish from peeling or flaking off, improving the longevity of your manicure.

What is a Dehydrator?

A nail dehydrator, on the other hand, is a product used to remove excess moisture from the nail plate. It helps to prevent the polish from lifting or peeling off due to excess moisture. The dehydrator also helps to disinfect the nail and prevent the growth of bacteria, yeast, or mold, which could cause nail infections.

Dehydrators typically contain acetone, isopropyl alcohol, or other solvents that dry out the nail surface quickly. Once the dehydrator evaporates, the nail surface is left completely dry, allowing the polish to adhere better.

Which one Should You Use First?

The general rule of thumb is to use the nail dehydrator first before applying the nail primer. The reason for this is that the dehydrator ensures that the nail plate is entirely dry before applying any other products, which helps the nail primer to adhere better.

When the nail is still moist, the nail primer may not adhere correctly, reducing its effectiveness. Also, if the nail is not correctly dehydrated, the nail polish may not dry well or may peel off quickly.

After using the nail dehydrator, it’s best to wait a few minutes to allow the nail to dry completely. Then, you can apply the nail primer and wait for it to dry completely before applying the nail polish.


In conclusion, nail primers and dehydrators are two essential products that can help improve the longevity of your manicure. Remember to use the nail dehydrator first to remove any excess moisture from your nail bed, and then apply the nail primer.

Also, keep in mind that using too much acetone or dehydrators can dry out your nails, leading to cracks and brittleness. So, be cautious with how often you use these products.

Finally, don’t forget to use high-quality nail polish and topcoat, and always protect your nails with gloves when doing activities that could damage them.
