The growth of hair beneath the skin, often referred to as ingrown hairs, occurs due to several factors related to hair follicles and skin conditions. Understanding these causes can help in prevention and management strategies to alleviate discomfort and reduce the risk of complications.
One primary reason for the development of ingrown hairs is improper hair removal techniques, such as shaving, waxing, or plucking. When hair is cut or removed too closely to the skin’s surface, it may curl back or sideways as it regrows, leading to its entrapment beneath the skin. This can result in inflammation, redness, and the formation of papules or pustules.
Moreover, individuals with curly or coarse hair are more susceptible to ingrown hairs due to the natural shape and direction of their hair follicles. Curly hair tends to grow in a spiral pattern, which increases the likelihood of it re-entering the skin as it grows. Consequently, individuals with such hair textures may experience ingrown hairs more frequently, particularly in areas where hair removal is common, such as the face, neck, underarms, and bikini area.
Additionally, certain skin conditions can predispose individuals to ingrown hairs. For instance, individuals with excessively dry skin may experience more ingrown hairs because dry skin can block hair follicles, making it difficult for hair to emerge properly. On the other hand, individuals with oily skin may develop ingrown hairs due to the accumulation of excess sebum, dead skin cells, and debris, which can clog pores and impede hair growth.
Furthermore, wearing tight clothing or engaging in activities that cause friction against the skin can exacerbate ingrown hairs. Tight clothing can compress the skin, leading to irritation and trapping newly grown hairs beneath the surface. Similarly, activities such as cycling or wearing restrictive clothing during exercise can contribute to the development of ingrown hairs, particularly in areas where friction is most pronounced.
In some cases, genetic predisposition plays a role in the likelihood of experiencing ingrown hairs. Certain individuals may inherit traits that make their hair more prone to curling back into the skin or their skin more susceptible to inflammation and irritation following hair removal. While genetic factors cannot be altered, understanding one’s predisposition can help in adopting preventive measures and choosing appropriate hair removal techniques.
Moreover, ingrown hairs may occur as a result of bacterial or fungal infections in the hair follicles. When bacteria or fungi enter the skin through small cuts or abrasions, they can cause inflammation and infection, leading to the formation of ingrown hairs. Maintaining proper hygiene and using clean shaving or waxing implements can help reduce the risk of infection and subsequent ingrown hairs.
Lastly, certain medications or hormonal changes can affect hair growth patterns and increase the likelihood of ingrown hairs. For example, hormonal fluctuations during puberty, pregnancy, or menopause can alter the thickness and texture of hair, making it more prone to becoming ingrown. Similarly, medications that affect hormone levels, such as oral contraceptives or hormone replacement therapy, may influence hair growth and contribute to ingrown hair formation.
In conclusion, several factors contribute to the growth of hair beneath the skin, commonly known as ingrown hairs. These include improper hair removal techniques, curly or coarse hair textures, skin conditions such as dryness or oiliness, friction from clothing or activities, genetic predisposition, bacterial or fungal infections, and hormonal changes or medications. Understanding these factors can help individuals take preventive measures and adopt suitable hair removal practices to reduce the occurrence of ingrown hairs and associated complications.

The growth of hair beneath the skin, known as ingrown hairs or pseudofolliculitis barbae in medical terms, is a condition that can lead to discomfort, inflammation, and potential complications if not properly managed. Delving deeper into the causes and contributing factors of ingrown hairs provides a comprehensive understanding of this common dermatological issue.
One significant factor contributing to the development of ingrown hairs is the method of hair removal employed by individuals. Shaving, for example, cuts hair at or slightly below the skin’s surface, which can cause the hair to regrow with a sharper edge, increasing the likelihood of it piercing the skin as it grows. Similarly, waxing and plucking can disrupt the natural direction of hair growth, leading to hair becoming trapped beneath the skin upon regrowth. Additionally, repeated friction from depilatory methods can irritate the skin, exacerbating ingrown hair formation.
The curvature and direction of hair growth also play a pivotal role in ingrown hair development. Individuals with tightly curled or coarse hair, particularly those of African descent, are more susceptible to ingrown hairs due to the natural spiral shape of their hair follicles. As the hair grows, it may curl back into the skin instead of emerging outward, leading to ingrown hairs, especially in areas where hair removal is common, such as the beard area, legs, and pubic region.
Moreover, certain skin conditions can increase the likelihood of ingrown hairs. Dry skin, for instance, lacks proper lubrication and may obstruct hair follicles, causing hair to grow irregularly and become trapped beneath the surface. Conversely, oily skin can accumulate debris and dead skin cells, creating a barrier that impedes hair growth and increases the risk of ingrown hairs. Individuals with pre-existing skin conditions such as eczema or keratosis pilaris may also experience more frequent ingrown hairs due to the abnormal buildup of keratin around hair follicles.
Clothing and lifestyle choices can also contribute to ingrown hair formation. Wearing tight-fitting clothing, especially in areas prone to friction such as the groin or underarms, can compress the skin and obstruct hair growth, leading to ingrown hairs. Similarly, activities that involve repetitive friction against the skin, such as cycling or wearing rough fabrics, can exacerbate ingrown hair development by causing irritation and inflammation.
Genetic predisposition plays a significant role in determining an individual’s susceptibility to ingrown hairs. Certain inherited traits, such as the shape and size of hair follicles, can influence the likelihood of hair becoming trapped beneath the skin. Additionally, genetic factors may affect skin sensitivity, inflammatory responses, and healing processes, all of which can impact ingrown hair formation and recurrence.
Furthermore, bacterial or fungal infections of the hair follicles can contribute to ingrown hair development. Staphylococcus aureus, a common bacterium found on the skin, can enter hair follicles through small cuts or abrasions, leading to folliculitis (inflammation of the hair follicles) and the formation of ingrown hairs. Similarly, fungal infections such as tinea barbae (barber’s itch) can cause itching, redness, and ingrown hairs in the beard area.
Hormonal changes and certain medications can also influence hair growth patterns and increase the likelihood of ingrown hairs. Hormonal fluctuations during puberty, pregnancy, or menopause can alter the thickness and texture of hair, making it more prone to becoming ingrown. Additionally, medications that affect hormone levels, such as oral contraceptives or corticosteroids, may disrupt the normal hair growth cycle and contribute to ingrown hair formation.
In conclusion, the growth of hair beneath the skin, or ingrown hairs, is influenced by a multitude of factors, including hair removal techniques, hair texture, skin conditions, clothing choices, genetic predisposition, infections, hormonal changes, and medication use. Understanding these contributing factors is crucial for implementing effective prevention and management strategies to reduce the occurrence of ingrown hairs and alleviate associated symptoms.
