How Long Does Nair Hair Removal Last? (Does it Expire)

Those of us that have chosen hair removal cream as our go-to hair removal method choose it because it’s EASY.

No need to schedule appointments, no need for pain… and in theory, no need for regrowth for weeks on end.

But as with all good things in life, there is a catch – Nair hair removal cream isn’t permanent.

So how long does Nair hair removal last?

It depends on the individual. Some people find that their hair takes longer to grow back after using Nair, while others find that it grows back at the same rate as if they had never used the product.

On average it will last for 3-5 days before needing to be reapplied.

Make sure you read our guide on how to use Nair hair removal cream properly to get the best results and make it last as long as possible!

How Long Does Nair Hair Removal Last?

The Nair treatment lasts for three to seven days, depending on the thickness of your hair. However, it is entirely dependent on how quickly your hair grows.

If your hair grows quicker than usual, it might only survive three days. Otherwise, a week is typical. This is a fairly easy method of hair removal therefore having to do it every few days isn’t a big issue.

At-home methods are not as effective as in-office treatments like laser hair removal. So, if you are looking for a more permanent solution, Nair is not the right product for you.

Nair is best suited for those who want an easy and painless way to remove hair from small areas like the upper lip or chin (or like I am, a big baby about the pain beauty brings … or is that just me?).

It is also a good option for those who are new to hair removal creams as it is gentle and easy to use.

How Does Nair Hair Removal Work?

Nair, for example, is a depilatory cream that uses chemicals to disrupt hair structure. Nair works by breaking down the protein bonds that keep hair follicles together. This makes the hair follicles weaker and easier to remove.

The three active components in Nair are potassium thioglycolate, calcium hydroxide, and sodium hydroxide.

These chemicals break down keratin, the protein that makes up the hair. Then, through a chemical reaction known as hydrolysis, hair and the root are converted to a jellylike substance.

Pure calcium hydroxide (slaked lime) and sodium hydroxide (lye) are both alkaline, with a PH of about 12. They do the trick rather well since hair destruction necessitates a PH of 10.

However, because these chemicals are extremely harsh on the skin, potassium thioglycolate is typically the main component in chemical depilatories, such as Nair products.

The hairs are now a soft goo in essence, and all that needs to be done is wipe them away with a cloth. Some Nair products also include Urea, which helps to exfoliate the skin.

Mineral oil, lanolin, and argan oil are used in Nair as additives to assist soften the harsh chemicals while maintaining the cream’s consistency.

Nair comes in different strengths for different body parts. It is available in a cream, lotion, or gel form.

The milder formulas are for sensitive areas such as the bikini line or face. Medium-strength formulas can be used on the legs, arms, and chest. The strongest Nair products are for the thickest hair on the body, such as the back or stomach.
