A lot of people are very much interested in getting rid of unwanted body hair. Whether it's on the face, limbs, torso, or more sensitive areas, there are quite a few places where hair can cause aesthetic or cleanliness problems, which is why it's not surprising that numerous hair removal methods have developed over the years. While shaving tends to be the go-to method most people use, a common alternative is to use Nair.

Nair is a highly effective and easily available cream that helps break down hair, so that it can be easily removed.

How Does Nair Work?

Nair is what is known as a chemical depilatory cream, which is to say that it's a lotion that uses chemical processes to destroy the components that make up hair, so that the hair can later be wiped away without issue.

The primary component of hair that Nair targets is keratin. Keratin is a protein that makes up various parts of the body, including fingernails and hair, which takes the form of various strands held together by sulfur-based bonds. Nair contains several ingredients that are designed to target these sulfur bonds, so that the keratin strands that make up hair end up detaching from each other and subsequently fall apart.

The primary ingredients in Nair are thioglycolic acid salts and sodium hydroxide (lye), which end up attaching to sulfur-based molecules and disrupt their chemical structure, leading to disintegration.

Application of Nair is a relatively simple process and involves applying the cream to an area covered in hair, waiting several minutes for the bonds that hold hair together to dissolve, and then scraping or washing it away. The result is a pretty even form of hair removal that lasts for as long as it takes for the hair to grow back.

It should be noted that Nair isn't able to affect the roots of hair, so it will begin to grow back as soon as it's removed, similar to how shaving works.

How Long Does It Take Nair To Work?

When applied to hair, Nair starts to work immediately, although it will take a little while for the cream to completely dissolve the bonds that hold hair together. Exactly how long this process takes depends on several factors, such as the exact Nair formulation used and the thickness of hair the cream is applied to, but generally speaking, it takes about 5 to 10 minutes for it to work.

Due to how there's much more keratin to break down in areas such as the legs, it's going to take a lot longer for Nair to work than places such as the upper lip, which will require only a minimal amount of time for it to work.

Where Can Nair Be Used?

There are alot of areas on your body that you can use nair, here are the bast places to use nair for safe and easy hair removal. 


Can you use nair on your legs?

Nair is perfect for use on the legs. Nair is specifically designed to remove very large swaths of hair quickly and of varying thicknesses, so it's best used for large body applications like the legs.


Can you use nair on the face?

For areas that require more precision, such as the face, you can still apply Nair to remove hair, although it's recommended you use more specialized versions, such as Nair specifically designed for the face, or at least one of the more sensitive formulations. Regular Nair is a bit strong for your face as the hairs tend to not be as thick and the increased lye content might cause issues as the skin on the face tends not to be as durable as it is on the rest of the body.


Can you use Nair on your private area?

You can use nair to remove hair around the genetal area, but do not use Nair directly on the genitals as it can cause burning or even iritation. 


 Where Should Nair Not Be Used?

It's important to keep in mind that while Nair can be an incredibly effective hair removal method, it's fundamentally a caustic chemical formulation that can cause some significant damage to more sensitive areas, so it's important to use it appropriately.


Do Not Apply Nair Directly On Genitals

For instance, while it's possible to apply Nair around your genital area, do NOT apply it directly onto your genitals. Genitals consist of incredibly delicate tissue that's highly responsive, meaning that if they come in contact with Nair, they'll probably endure a lot of damage in the form of chemical burns and the experience will be exceptionally painful.

This should be taken into account especially if you plan on using Nair multiple times as repeated chemical burns can cause permanent damage.


Do Not Apply Nair Too Close To The Eyes

It's also a good idea to avoid applying Nair to other areas in general, such as on your eyebrows. Not only are eyebrows overly sensitive, but they're located near the eyes, which are places you should avoid getting Nair into at all costs. If your eyes come in contact with your eyes, you'll probably need some degree of medical attention to prevent permanent damage.


Do Not Apply Nair Directly On The Nipples

Another place you should avoid applying Nair to are the nipples as Nair can easily cause them to get chemical burns and while you can apply Nair to your armpits, you should make sure to get it all off when you're removing the hair as it's an area where Nair can easily cling to and cause long-term irritation if not properly gotten rid of.

How Long Does Nair Remove Hair For?

Nair doesn't reach down too deeply, but it does a pretty decent job of eliminating hair slightly below the skin, so the timetable for hair regrowth is a bit long.

Depending on the length of hair and thickness of hair, it can take anywhere from a couple weeks to a couple months for hair to grow back. Typically, hair around the face takes about two weeks to grow back completely and leg hair takes about a month and a half. Hair around genital regions tends to take the longest to regrow, with upper lip hair taking the shortest amount of time.

Most other types of hair take somewhere in between.

Is Nair Better Than Shaving?

Whether or not Nair is a better choice for hair removal than shaving is really up to personal preference, as both methods have their own advantages, however, there are quite a few reasons why Nair might be a better choice.

The biggest reason why people prefer using Nair over shaving is because it's able to much more perfectly get rid of hair over a large area. When shaving body hair, it's incredibly common for people to miss large patches of hair or to cut hair unevenly, resulting in sub-par results. This is especially the case when it comes to areas like the back of the legs, which are very difficult to see.

Nair, however, when lathered onto an area, pretty decently coats entire hair filaments, so the breakdown of the hair is much more complete. It also reaches slightly below the skin, so it's going to eliminate more hair than shaving alone can. While it won't absolutely remove 100% of hair, it's much more precise than using a razor and won't nearly require the same amount of effort.

Razors also come with the issue of becoming dull over time, which limits their effectiveness. Although this can be annoying since you need to replace razors frequently, it's much more of an issue due to the fact that you're not always going to be immediately aware of when it stops working properly, so it's entirely possible you'll need to re-shave areas repeatedly.

An additional advantage to using Nair is that it tends to take much less time to work. Depending on what you're shaving, it's entirely possible to spend more than an hour getting rid of hair, whereas all you need to do is spend a maximum of ten minutes waiting for Nair to completely break down molecular bonds.

Of course, Nair isn't for everyone and there are reasons why despite having access to it, a lot of people give it a pass. Most of the disadvantages of Nair come down to its caustic chemical nature.

Nair is incredibly strong and it can easily cause burns and skin damage if applied for too long. For people with sensitive skin, it might be outright impossible to use Nair without experiencing a tremendous amount of discomfort.

There are also some limitations to applying Nair as it cannot be used on very sensitive areas like the genitals.

Nair also has a distinct and unpleasant "sulfur" smell that results from chemical reactions in the creme, which can be incredibly off-putting.

Overall, Nair tends to be more convenient and effective than shaving, but its harsh nature doesn't make it ideal in a variety of situations.

Does Nair Cause Ingrown Hairs?

When considering hair removal, one big issue that comes up a lot is ingrown hairs. Ingrown hairs occur when hair that's regrowing end up getting stuck under the skin, rather than growing outward. Ingrown hairs are often painful and it's common for them to cause hair follicles to swell up and become infected, which can result in a litany of issues.

When you want to get rid of body hair, it's a good idea to prioritize methods that limit the prevalence of ingrown hairs. Fortunately, Nair is pretty good when it comes to avoiding their development.

The reason for this is because Nair is good at breaking down the debris that ends up plugging up hair follicles in the first place, meaning that it's less likely hairs will regrow improperly.

Nair Side Effects

Although it's common for people to use Nair with no problems, that doesn't mean that there are no unpleasant side-effects people might experience. Possible side-effects of using Nair include:

  • Allergic reactions
  • Skin irritation
  • Chemical burns
  • Lingering redness

Skin irritation, and to a lesser extent chemical burns, are the most common negative effects of using Nair and their prevalence is largely determined by skin sensitivity and whether it's properly applied.

Allergic reactions are less common, but they do occur in some people, usually in the form of hives. While there are any number of ingredients that can cause allergic reactions, it's usually the perfume components that are responsible.

Like many forms of hair removal, redness around the application area isn't uncommon, although it tends to go away in a couple hours and is mostly painless.


Nair is an incredibly versatile cream that's easy to use, which is why it's such a popular form of hair removal. Although it can't be used on all areas, Nair is a quick way to remove large amounts of hair without having to focus too much on what you're doing as it just involves placing it on a particular area and chemical reactions take care of the rest.

Whether or not it's best for you will depend on a lot of factors, such as skin sensitivity, but it's a viable option for most people and rivals many other methods of hair removal in terms of effectiveness.

Hair removal tools like razors or epilators come with their own advantages that might make them more appealing to you than using harsh chemical compounds, so it's best to keep your options open when thinking about getting rid of hair. That being said, assuming you don't experience any exceptionally bad effects from using Nair, the cream makes for a very easy solution that you should seriously consider.
