Hereditary Hair Loss (Male and Female Pattern Hair Loss)
Hereditary hair loss, the most common cause, is attributed directly to your family’s genetics. This condition is also known as androgenetic alopecia and is associated with hormone levels and aging. This occurs in both men and women and is more commonly referred to as male/female pattern hair loss. Hereditary hair loss is typically gradual and appears in noticeable patterns.
Stress-Related Hair Loss
Telogen effluvium occurs when a significant number of hair follicles enter the resting phase prematurely, leading to noticeable shedding. This condition is often triggered by physical or emotional stress, illness, or hormonal changes, such as postpartum or menopause. While the shedding is temporary, addressing the underlying cause and supporting scalp health can accelerate recovery.
Nutritional Deficiencies
Deficits in key nutrients such as iron, zinc, vitamin D, or biotin can cause hair loss. Without adequate nutrition, hair follicles may weaken, resulting in thinning and shedding. Addressing deficiencies through dietary changes or supplements can help restore hair strength and promote healthy regrowth over time.
Hormonal Changes
Hormonal changes such as childbirth, pregnancy, menopause, and various thyroid conditions have a history of causing slow and prolonged hair loss. These imbalances impact the growth cycle of hair follicles, causing prolonged shedding. Treatments targeting the underlying hormonal issues often help stabilize hair loss and improve hair density.
Beauty Treatments and Hairstyles
Beauty treatments that include harsh chemicals or continuous use of heating tools can cause inflammation of the hair follicle and can lead to sudden hair loss. Traction alopecia results from prolonged tension on hair follicles caused by tight hairstyles, such as braids, ponytails, or extensions. This condition can lead to weakened follicles and hair loss, especially along the hairline. Preventative measures include adopting gentler styling practices and avoiding excessive tension, while treatment may involve stimulating regrowth and repairing the scalp.
Medication and Supplement Intake
Hair loss may be a side effect of certain oral medications, including chemotherapy, antidepressants, and blood pressure drugs. This shedding, often temporary, occurs when the drugs disrupt the hair growth cycle. In many cases, hair regrowth resumes once the medication is adjusted or discontinued, alongside supportive treatments to nurture the scalp. If you believe a medication is causing hair loss, contact your dermatologist to express your concerns before you stop taking the medication.
Fungal Infections
Tinea capitis is a fungal infection of the scalp that causes hair loss in round patches, often accompanied by redness, scaling, and itchiness. This contagious condition primarily affects children but can occur in adults. Antifungal treatments effectively combat the infection, allowing hair to regrow in the affected areas.
Underlying Autoimmune Conditions
Underlying autoimmune conditions may also play a role in gradual hair loss and/or sudden bald patches. People with a history of prior autoimmune diseases like vitiligo may be more likely to experience hair loss at some point in their life.
