Shaving

Shaving removes the tapered tip of a hair. Cutting this tip off leaves the growing hairs feeling bristly. As the sharpened hair tip continues to grow, there is a risk of ingrown hair if it penetrates the skin surrounding the follicle. Inflammation and irritation can result.

On the plus side, shaving is quick and, at least initially, inexpensive. On the downside, hair stubble reappears quickly (immediately if shaving is not done properly). Since a sharp blade is being used, there is a risk of nicks and cuts to the skin, resulting in bleeding. Skin irritation can occur if a shaver is used repeatedly over the same area or if it is not kept clean. Ingrown hairs can also occur if the blade is not kept sharp.

Shaving in the same direction as the hair growth is the most comfortable, while shaving against the hair growth can give a much closer shave. Many people use a combination of these methods. Dermatologists however warn that shaving against the hair growth can cause ingrown hairs and increased irritation, making the skin sore and sensitive.

Another potential side effect is razor bumps. This is where hair curls around after being cut, and enters the skin at another place. The sharpened hair penetrates the skin, causing irritation, inflammation, skin eruption, and pain. As the hair continues to grow deeper into the skin, scar tissue can develop around the area. This effect is known as "razor bumps".

Costs can add up, too. Although the price of an individual razor is very small, a new one must be used every few days. Because of this shaving can become one of the most expensive hair removal solutions available.


Blade duration can vary between individuals, based on the thickness or coarseness of the hair. It typically needs to be changed after every 3-7 uses.
