Razor bumps or ingrown hair are skin issues that occur after shaving. Both terms are used to describe cases where hair grows back into the skin after shaving, causing the formation of red bumps.

Razor bumps can appear on any body part that can be shaved. The most common places include the underarms, groin, legs, and face.

Herpes, on the other hand, is a viral infection that causes symptoms that are visible on the skin. Often, herpes and razor bumps are mistaken for each other because they both cause bumps or sores to appear on the skin. However, they are in no way related. So, what differentiates them?

Ingrown hair (razor bumps) vs herpes: The differences

The major difference between herpes and ingrown hair is in their causes. While herpes is a sexually transmitted disease that often occurs after a person comes in sexual contact with an infected person, ingrown hair only occurs when hair grows back into the skin after shaving.

Herpes and ingrown hair also differ in their signs and symptoms. Below is a table highlighting the differences between herpes and ingrown hair.

Herpes vs. ingrown hair


Razor bump or Ingrown Hair


Herpes occurs mainly in the genital or rectal areas and also around the oral region

Razor bumps are found anywhere that hair grows and not limited to the genital and oral areas

Time of occurrence

Herpes can occur at any time so long as a person is infected with the herpes simplex virus

Ingrown hairs or razor bumps occur mainly after shaving


Herpes does not have a permanent cure, it is a lifelong infection that can only be managed or suppressed

Ingrown hair or razor bumps can be permanently treated using both topical medications and natural remedies

Mode of treatment

Herpes cannot be treated or managed at home; it has to be treated by a doctor.

Ingrown hairs can be treated using home remedies or over the counter products.


Herpes always appear as clusters of sores and blisters or brown crusts after the blisters rupture, visible on top of the skin affected

Ingrown hair or razor bumps are small bumps under the skin. They often look like small reddish rashes

Severity of pain

Herpes always causes severe pain in the areas affected

Ingrown hairs causes pain mostly when you apply pressure in the affected area

Frequency of occurrence

Herpes infection can cause regular outbreaks. People with HSV 1 might have up to 2 outbreaks a year, while HSV 2 presents more frequent outbreaks.

Ingrown hairs barely occur at random. They only get triggered when hair grows back into the skin after shaving.

Causes of ingrown hair (or razor bumps)

Ingrown hair occurs when the sharp edge of the hair grows back into the skin after shaving. The hairs become irritating to the skin, and to try to ward them off, the skin sends out some inflammatory cells.

The inflammatory cells then cause the appearance of red bumps (also called razor bumps) in the affected area. The main things that cause the hair to grow back are when the razor cuts through the skin or when the hair is too curly.

By learning how to shave without getting razor bumps, you can reduce the chances of such an occurrence.

  • Darkening of the skin in the affected area
  • The feeling of tenderness or softness in the affected area when touched
  • Itching and burning sensation
  • Pus-filled lesions
  • Red or inflamed bumps

Causes of herpes

Herpes is a viral infection caused by the herpes simplex virus (HSV). Herpes causes sores or blisters in areas like the mouth and genitals.

There are two types of herpes - HSV type 1 and HSV type 2.

HSV type 1 leads to oral herpes and affects the mouth and skin around the mouth region. It also affects the genital area.

HSV type 2 causes genital herpes3 and is sexually transmitted.

However, oral herpes is more easily diagnosed than genital herpes because most people infected with HSV -2 do not have the typical symptoms.4

People contract HSV 1 and HSV 2 in different ways.

The common ways HSV type 1 can be contracted are:

  • Skin contact - Herpes can be transmitted through skin-to-skin contact. HSV present on the moist skin of the mouth and genitals can be transmitted from one person to another
  • Through sharing food utensils, lip balms, or razors with another person with cold sores
  • Any activity that exposes you to an infected person's saliva like lipsticks and make-up brushes or mouth-to-mouth contact1
  • Having oral sex with a person that has the oral herpes virus

HSV type 2 can be contracted by:

  • Having sex without the use of protection (this is the easiest way to get genital herpes)
  • Sharing sex toys with others who have the infection
  • Open sores during breastfeeding
  • Engaging in oral or genital sex with someone infected with herpes

How to identify herpes

Mouth sores caused by herpes simpex virus

  • Sores on your genitals or around your anus
  • Itching, tingling, or burning sensation
  • Fever
  • Muscle aches
  • Painful urination
  • A repeated outbreak of the sores
