Shaving methods

The shaving technique and shaving routine also affect the lifespan of your razor blades. The force you apply and the rate of strokes each shave influence your product’s longevity.

Shaving surface area

The bigger the surface you shave, the more regularly you will change your razor blades. However, there are some different surface areas with various kinds of hair growth each shaver can check out:

  • Chin
  • Cheeks
  • Mustache
  • Scalp
  • Neck
  • Body hair

For instance, the hair on your mustache is prone to be coarser than your body hair, producing more damage to your blade per stroke.  

Essential Methods To Extend Your Razor Blade Life

Learning proper methods to prolong your razor blade lifespan brings you various benefits. Here are some must-try ways to extend your product longevity.

Keep your blades dry

After the shaving process, it is critical to keep your razor blades in well-ventilated areas. If water remains on the item after shaving and you haven’t cleaned it properly, oxygen and salt residue from your skin will make it rust.  

Therefore, the most helpful tip is to make sure you dry off your item before storing it by using a blow dryer or dry and lint-free cloth to remove any water. Then, dip your razor blade (not the handle) into almond oil, baby oil, and mineral oil. 

Water and oil don’t mix, so these oils work as a sealant to avoid oxidation issues and prevent moisture from reaching your blade. 

Finally, maintaining it in a dry and cool place is tactical, including closets and your bedroom closet.

Apply proper shaving techniques

In general, using correct shaving methods prolongs your item’s life span. Moreover, it is best to use the three-pass shaving method to get a close shave. However, this technique may make your blades dull faster than a single pass. 

As a result, performing the first pass with the grain is advisable if you are a beginner.

Use the stropping method for straight and safety razor blades

Stropping to extend the blade’s sharpness is also another excellent strategy to prolong your safety and straight razors’ life.

Use a pair of expired blue jeans or belt and sharpen the blades along the direction of razors. Then, apply enough force to run the razor against the old jeans.

Most shaving creams include acids, such as glycolic acid and salicylic acid.

Unfortunately, these acids wear down your product speedily, leading to expired blades. As a result, purchase shaving creams that possess medium or low acid content to help your razor blades last longer.

Besides, being generous when using shaving cream is one of the most helpful tips after purchasing medium acid content products. This way boosts the longevity of your disposable, electric, and safety razors effectively because the better greased the surface of your skin is, the less resistance there will be when your blades pass over.
