How long does a safety razor blade last?

The average lifespan of a razor blade is about 7 days. In other words, you can shave 6 – 7 times.

Of course, there are razor blades that last longer than a week. There are also ones that become dull more quickly.

Many factors can affect the quality of the razor blade. The durability of the razor blade depends on how you use it, how you maintain it, and most importantly, where you store it.

Not only that, but a poor shaving technique can also negatively impact the construction of the blade.

The top factors that give effects on the quality of a safety razor blade are:

  • Type of hair
  • The area of the shaving surface
  • Quality of safety razor blade
  • Shaving technique
  • Frequency of shaving
  • Blade maintenance and storage

You can see my full explanations of each factor below.

How often should I change a razor blade?

As mentioned above, a razor blade can last for about 7 days on average. You should replace the blade every time after shaving for 6 – 7 turns.

However, if your budget allows, I advise you to change the blade after every shave ideally. 

If you want the blade to last longer, you need to maintain it regularly.

Below, I explain when you know you should change the blade. You can also learn some useful tips for maintaining the item to keep it lasting longer.

Factors That Affect A Safety Razor Blade’s Longevity 

I have listed the top 7 factors that affect the longevity of a razor blade. In this section, I will explain all of those clearly.

Type Of Hair

The hair type is the first factor that causes dullness in the razor blade. You need to check whether your hair is thin, peach fuzz, 5 o’clock shadow, coarse, or thick?

The thicker the hair is, the faster the razor blade edge may become dull. 

Also, remember that hair on different body parts has a specific amount of thickness. The blade will last longer if you shave only on the face than when you shave on the neck, face, and head.

The hair follicle thickness and coarseness leave a huge impact on the durability of the razor blade. You may not know this, but human hair is as strong as copper wires. The thicker the hair is, the more impact the blade has to endure.

Due to the impact of the thick and coarse hair, the edge of the blade will lose its sharpness over time. 

A person with fine hair can usually use the blade longer than one with thick hair. This fact is correct for both facial hair and other types of hair.

The Area Of The Shaving Surface

Another factor that impacts the downgrading speed of the safety razor blade is the shaving area (shaving surface). Of course, the larger the surface is, the more hair the razor head has to get rid of, making the blade lose its shape quicker.

Most men grow hair thickly on their faces. However, they do not have much hair on the neck surface. In this case, the blade will not have to work much.

On the other hand, some men have hair growing a lot on both the face and right under the neck. Some even have hair growing all around their face. As a consequence, they need to use the blade to shave all these areas, causing the item to its sharpness rather quickly.

Also, some people use razor blades to shave their legs instead of their faces. The legs have a wide surface of thick hair. Doing this job will result in more impact on the equipment.

Quality Of Safety Razor Blade

It is not all about the external factors; the construction of the razor blade also decides its longevity. 

It is easy to understand that one blade is more durable if it has quality construction.

Normally, the materials that the manufacturers use to build the blade are:

  • Stainless steel
  • Stainless steel alloy
  • Copper
  • Metal

The most durable materials are stainless steel and stainless steel alloy. In addition to the construction material, you should also pay attention to the coating to check the hardness of the blade.

Most razor blades today come with a coating. Quality coating materials such as platinum, chromium, tungsten, etc will provide smooth cuts and minimize skin irritation. The coating finish will increase and prolong the sharpness, limit dullness, and increase user satisfaction.

Shaving Technique

If you have a good shaving technique, you can keep the shaving tool durable. The right technique should have a balance between speed, force, and shaving direction.

Most men use a 3-pass technique, which contains the following ways:

  • Shaving with the grain in the same direction of the hair growth
  • Shaving horizontally to the hair growth
  • Shaving oppositely to the grain (against the direction of the hair growth)

Unfortunately, the 3-pass technique will make the blade dull quicker due to the fact that it requires 3 turns of shaving instead of one pass. However, this technique allows you to get a super close shave on your face.

The best way to shave is to make the first pass to the grain and then another pass against it.

Frequency Of Shaving

Different people have different frequencies of shaving. 

As I have mentioned above, a safety razor blade can last for about 7 days. This statement is true if you do the shaving job once per day.

Technically, the shaver will completely lose the sharpness after it is applied for 6 – 7 turns. So if you shave 2 or 3 times per day, you will have to replace the item after half of a week (3 – 4 days, in other words).

It does not mean that you can use the razor blade for more than 7 days if you have not done 7 shaves in a week. The reason is, even when you do not do the shave, the shaver still wears out due to the oxidation process.

Blade Maintenance And Storage

The maintenance and care of the razor blade after use are extremely necessary.

After use, you need to carefully clean and store the razor blade in a cool, dry place. In addition, you should also pay attention to periodically sharpening the blade to increase the life of the blade.

How Do You Know A Safety Razor Blade Needs To Be Changed?

A dull blade usually damages the skin on the area where you shave. Therefore, if your skin is irritated, this means that the razor head has become less effective. At this time, you should change the old blade to a new one.

On the other hand, a sharp blade can support smooth shaving. If you don’t notice any difficulty while shaving, probably the blade is still decent.

You can also decide the time to replace the razor, depending on the type of your stubble.

If you have coarse stubble:

  • Change the blade 2 times per week (for shaving 4 – 7 days a week)
  • Change the blade 1 time per week( for shaving less than 3 days per week)

If you have medium stubble:

  • Change the blade 2 times per week (for shaving more than 4 days a week)
  • Change the blade 1 time per week (for shaving less than 3 days a week)

If your have soft stubble:

  • Change the blade 1 time per week (for shaving every day)
  • Change the blade 1 time every 2 weeks (for shaving less than 3 days per week)

Tips To Make A Safety Razor Blade Last Longer 

Clean & Dry The Blade After Using

Some factors, such as excess beard, dead skin, salt on the skin, or active ingredients in shaving cream, after shaving accumulate on the blade, which can reduce its life.

For this reason, you should remove these particles after shaving. This work is very simple. After shaving, you rinse the razor and blade, dip in alcohol to remove excess water. Use a soft towel to dry the blade. If you want to be extra careful, you can apply a thin layer of baby oil to limit oxidation.

On the other hand, you should carefully choose where to store it. Storing the blade in a dry, well-ventilated, and low-humidity location is the most appropriate option.

Strop The Razor

Stropping is another good way to create a sharp edge of the razor. You need to follow 5 steps to do this work.

  • Step 1: Hang an end of a strop on a hook, and pull the other end until the strop is taut. 
  • Step 2: Put the straight razors flat against the strop. Remember to keep the spine and the blade edge in the strop.
  • Step 3: Move the blade towards you to strop it.
  • Step 4: Flip the blade to the other side.
  • Step 5: Repeat from step 2 to strop the other razor side.

Oil-coated Razor Blade

If you want to be extra careful, after cleaning you can use natural oils to limit oxidation.

You can soak a cotton ball with oil and apply a thin tire to the blade. Or dip the entire blade in a cup of oil, then place the razor on the paper to absorb the excess oil and let it dry.

Storage Place

The last thing to do is find a safe storage place for the razor.

The storage should be dry and have a low level of humidity.

Suitable containers such as you can store the razor are boxes, cabinets, and vacuum bags.

An airtight plastic container is a good place to store razor blades.
