Ideally, you want to change your razor blade after 5-10 shaves. Gillette actually recommends 5-7 shaves, but this is just a general rule and it actually comes down more to the thickness and density of your facial hair.
Single blade razors are more efficient because it cuts facial hair closely without creating more blade friction than needed, which means fewer chances of getting a skin rash after getting a shave. Single blade razors, by design, are also more sustainable.
According to the American Academy of Dermatologists, you should change your razor blades or throw away disposable razors after every five to seven shaves, if not sooner.
Reusable razor blades typically last five to 10 shaves; but, just like disposable razor blades, the best way to gauge when to replace a blade cartridge is dullness.

The best indicator it's time for a new blade is dullness. If your razor blade pulls at your hair, feels rough on your skin or you notice more skin irritation than normal post-shave, it's time to replace it.
Unlike razor burn, which shows up right after shaving, razor bumps can take days to appear. They also take a longer to go away and can leave scars in some cases. Razor bumps tend to resolve on their own, within 2 or 3 weeks of shaving. However, some people get them with every shave.
Most of the dermatologists recommend two blades as they seem to prevent nicks, as the razor head occupies less area on sharp curves and it's easier to control. They also happen when the razor pushes down on your skin, forcing your skin into a hill in front of the it.
While using a single blade razor, you have the ability to cut cleanly through the hair, significantly reducing your chance of ingrown hairs and skin irritation. This is due to the fact there is no additional blades tugging and pulling and cutting the hair below skin level.
As far as razors go, it's best to use a twin-blade razor, which is the best razor for sensitive skin. Single-blade razors tend to pull on the skin, while four-or-five-blade razors are a bit too powerful, so they're likely to cause irritation when dealing with acne-prone skin.
#4 – Safety Razors
A slight edge of a single razor blade makes contact with the skin – preventing the blade from cutting into the skin. Hence the name – safety razor. These razors consist of a permanent handle with a metal head which holds a replaceable, single stainless steel razor blade with two sharp edges.
Ensure that the razor blade is replaced every 5 to 6 shaves or when the razor itself seems to do more pulling than cutting. More blades will not result in a better shave; fewer blades with proper planning and preparation will.
If more blades make you worry about nicks, you're not alone. Some dermatologists recommend no more than two blades to avoid nicks. When razor heads occupy more area on sharp curves, the razor is harder to control. If the blade can't match the surface, you'll nick yourself [source: Burns].
While most men are comfortable with electric or disposable razors, there are benefits to using safety or straight razors — both of which will last a lifetime. Our top pick, Gillette's Fusion Proglide, provides a close shave with a long-lasting five-blade head.
Once an initial crack forms, the blade is vulnerable to further chipping. As more cracks accumulate around the initial chip, the razor's edge can quickly dull. The blade's microscopic structure plays a key role, the team found. The blade is more prone to chipping if the microstructure of the steel is not uniform.
If your blades still seem to be rusting quickly, it probably means your bathroom has a high level of humidity that is settling into the blades between shaves. Swipe the blades with a small amount of baby oil or Vaseline after drying. This will help naturally repel water.
Shaving Treatment
Shaving can leave behind painful razor burn and pesky ingrown hairs. For an easy fix, apply Vaseline to the legs post-shower, specifically while the skin is still slightly damp.
Instead, they're triggered by your hair growing back after waxing or shaving. If you experience herpes outbreaks, they may occur on a fairly regular basis. People with HSV-1 typically have one to two outbreaks per year, while people infected with HSV-2 can experience more frequent outbreaks.
You probably don't need to shave every day. Razors don't just cut off your hair, they take a layer of skin cells with it every time you run the blade across your skin. Unless you're looking to achieve a completely hairless look, you can skip at least a day or two between shaving sessions to allow your skin to heal.
For those that like the feel of smooth, hairless arms, shaving will be beneficial. Because hair holds onto moisture, shaving your armpits may result in less sweating, or at least less noticeable sweating (sweat rings on your shirt sleeves, for example). Shaving may also cut down on the odor associated with sweat.
Polyethylene Glycol Ingredients
The strips on a razor that contain the lubricant to help achieve a closer shave contain a pretty nasty chemical call polyethylene glycol (PEG). PEG is a petroleum-based compound that is widely used in cosmetics as a solvent, softener or a moisture-carrier.
Like hair on your head, your pubic hair may also thin out with age. If you've got a lush patch now, many factors could thin it, make it go gray or white, or even cause it to bald. For ladies, menopause is one of them. For men, it's the natural aging process and dropping testosterone levels.
