What is Ingrown Hair?
Hair removal techniques such as shaving or waxing are the most common cause of ingrown hair. These methods cause the hair to break off at, or just beneath the surface of the skin, and often create a sharp tip where the hair has been cut.
As this damaged hair attempts toregrow, it may begin to curl in on itself and become trapped in the follicles, grow into another nearby follicle, pierce the sidewall of the follicle, or grow sideways into the epidermis of the skin.
Basically, shaving and waxing do not leave a nice blunt end, and this can prevent hair from growing straight up through the follicle opening. Hair growing at an angle can become trapped in the follicle or pierce the skin, causing redness and inflammation. Apart from this, plucking can also damage the follicles and inhibit new growth from breaking through the surface of the skin.
While ingrown hair can appear on any part of the body, whereas it is most common in areas where hair is coarse or where frequent shaving occurs. Men usually have the most problem on their chin and neck, whereas, women experience ingrown hair most often on their pubic area, underarms or along the bikini line.
