What Can Cause Hair Loss

Hair loss can be an upsetting experience for many people, affecting not only their appearance but also their confidence and self-esteem. Being able to understand the various causes of hair loss and help empower individuals to take proactive steps to manage and solve their hair loss. By gaining insight into these causes, you can better understand and learn how to properly address hair loss and seek appropriate treatment options.

Some common causes of hair loss include:

Genetics:

Genetics can play a significant role in hair loss through conditions such as androgenic alopecia, or male-pattern and female-pattern baldness. These conditioners can be inherited, and a family history can increase the likelihood of experiencing it. Individuals who suffer from androgenic alopecia may have hair follicles that are much more sensitive to androgens, such as testosterone and DHT. This then causes the hair follicles to shrink over time, leading to a shortened hair growth cycle and follicle miniaturization, resulting in thinner and shorter hair. The pattern of hair loss varies, such that men are more likely to experience receding hairlines and thin at the crows, whereas women may experience thinning and widening of the part line. Treatments often include topical and oral medications, laser therapy, and hair transplants. This can then help manage and slow down the progression of genetic hair loss. Moreover, consulting with a healthcare professional can help determine the best course of action based on the individual's symptoms.

Hormonal Changes:

Hormonal changes can be one of the causes of hair loss in numerous ways, particularly in response to fluctuations in androgens, such as testosterone and DHT. An imbalance in such hormones can lead to hair follicles becoming sensitive, therefore leading to a shorter hair growth cycle and resulting in thinner, weaker hair. For instance, during pregnancy, childbirth, or menopause, a significant hormonal shift takes place and could cause temporary hair thinning known as telogen effluvium. Additionally, thyroid imbalances can disrupt the normal growth of hair. For example, in men, elevated levels of DHT may contribute to male-pattern baldness, whereas women may experience the thinning of hair due to hormonal changes during menopause or other endocrine disorders. This, identifying the underlying cause of hormonal changes is significant to managing hair loss, and a healthcare professional can help recommend appropriate treatment options based on the individual's symptoms.

Medical Conditions:

Medical conditions can be a cause for hair loss through a variety of mechanisms, often affecting the hair growth cycle or damaging the hair follicles. Autoimmune disorders such as alopecia areata can lead to patchy hair loss as the immune system can attack healthy hair follicles. Conditions such as lupus or diabetes may also cause hair loss due to inflammation or changes that occur in blood circulation. Scalp infections, including fungal infections like ringworm, can very much disrupt hair growth and therefore lead to hair loss. In addition to this, chronic illnesses, like cancer, can result in hair loss for both the disease and the treatment like chemotherapy. Identifying and treating the underlying medical condition is crucial to dealing with hair loss, and consulting with a healthcare provider can help determine the best steps to tackle this issue based on the individual's circumstances.

Medications:

Certain medications can cause hair loss as a side effect, typically by interfering with the hair growth cycle or damaging hair follicles. Drugs that are used in chemotherapy are well-known for causing rapid and noticeable hair loss due to their effect on fast-growing cells, including hair cells. Other medications, such as those that treat depression, arthritis, hypertension, and gout, may also contribute to hair loss. The severity and type of hair loss varies depending on the medication and the individual's response. If you suspect that a medication you are taking is causing your hair loss, consult with a healthcare professional to discuss the potential alternatives and adjustments that can be made to your treatment plan.

Stress:

Stress can be one of the causes of hair loss. This can be through conditions such as telogen effluvium, in which emotional or physical stress disrupts the hair growth cycle. When the body experiences high levels of cortisol, hair follicles may prematurely enter the resting phase of the hair cycle and can fall out in bigger chunks than normal. This type of hair loss usually occurs a few months after a stressful period/event in one's life and is usually temporary, with hair regrowth occurring once the stress is resolved. Chronic stress can also exacerbate other underlying causes of hair loss, such as hormonal imbalances. To prevent stress-related hair loss, you should manage stress through relaxation techniques, exercise, and being consistent with a proper sleep schedule. Consulting a healthcare professional can also offer some guidance as to addressing any persistent hair loss.

Nutritional Deficiencies:

Nutritional deficiencies can lead to hair loss by disrupting the normal hair growth cycles and affecting the health of hair follicles. Iron, zinc, vitamin D, and certain B vitamins, especially biotin are key nutrients that play a significant role in maintaining healthy hair. If an individual lacks these nutrients in their diet it can lead to brittle, weak hairs and they are prone to falling out. For example, iron deficiency can reduce the oxygen transport to hair follicles, while protein intake may limit the hairs' ability to grow. Ensuring a balanced diet rich in essential vitamins and minerals is crucial in promoting healthy hair growth. If you suspect that you have a deficiency that is causing hair loss, consult with a healthcare professional for an evaluation and potential supplementation.

Hairstyling Practices:

Certain hairstyling practices can cause hair loss if they put excessive strain or damage on the hair and scalp. Tight hairstyles, such as ponytails, braids, and buns, can lead to traction alopecia, a form of hair loss caused by prolonged tension on the hair follicles. Heat styling tools like straightening irons, curling irons, and blow dryers can weaken and damage the hair shaft, which can then cause breakage and thinning. Frequent chemical treatments such as colouring, perming, and relaxing can also damage the hair and scalp, which then increases the risk of hair loss. Additionally, over-bring or using harsh hair products can irritate the scalp and damage the hair. To prevent this you would have to adopt gentler styling practices and avoid tight hairstyles and excessive heat or chemical treatments.

Infections:

Infections can cause hair loss by affecting the health of the scalp and hair follicles. Fungal infections such as ringworm can invade the scalp which then causes inflammation, itchiness, and hair loss in patchy areas. Bacterial infections, like folliculitis, can cause inflammation and damage to the hair follicles, then resulting in hair loss. In some cases, severe infection may cause scarring, which then permanently damages the hair follicles and leads to permanent and irreversible hair loss. Early diagnosis and treatment of scalp infections are crucial for preventing further hair loss and promoting healthy hair growth. Consulting a healthier professional is recommended for accurate diagnosis and appropriate treatment options, which may include antifungal or antibiotic medication.

Autoimmune Diseases:

Autoimmune diseases can cause hair loss as the immune system mistakenly attacks healthy hair follicles, which leads to the disruption of the hair growth cycles and hair loss. One common autoimmune disorder that affects hair growth is alopecia areata, where the immune system targets hair follicles, causing round patches of hair on the scalp and other parts of the body. Other autoimmune disorders like lupus and scleroderma can also lead to hair loss due to inflammation, scarring, and other damage that is caused to the hair follicles. The severity and pattern of hair loss may vary depending on the specific autoimmune disorder. Early diagnosis and treatment are important to manage the underlying autoimmune disease and potentially mitigate hair loss. Consulting with a healthcare professional can help determine the best course of action, which can include medication to suppress the immune response and prompt hair regrowth.

Age:

As we age, hair loss becomes more common due to a combination of factors. Hair growth naturally slows down over time, and the hair follicles may shrink and therefore lead to a thinner and weaker hair appearance. The growth phase of the hair cycle becomes shorter, thus resulting in less active hair growth and more hair to reside in the resting phase. Additionally, ageing can lead to hormonal changes, such as a decrease in oestrogen in women and an increase in DHT sensitivity in men, which can then contribute to hair loss. Age-related health issues, like certain scalp conditions and medication, may also play a role. While age-related hair loss is often a normal part of the ageing process, maintaining a healthy lifestyle and proper hair care can help manage and slow down these effects. If hair loss is a concern to you, consult a healthy professional to get guidance on potential treatments and care options available to you.
