There are many causes of hair loss and for many it will be a temporary loss secondary to medication or illness: The most common cause of hair loss is androgenetic alopecia, also known as male or female pattern baldness. This hereditary condition is influenced by genetics and hormones, particularly dihydrotestosterone (DHT). In men, it typically causes a receding hairline and thinning at the crown, while women may experience diffuse thinning over the scalp. It often progresses with age and can begin as early as the late teens or twenties.
Another frequent cause of hair loss is telogen effluvium, a condition where hair enters the resting (telogen) phase prematurely due to stressors. These triggers can include physical or emotional stress, illness, surgery, childbirth, or significant changes in diet. Hair loss associated with telogen effluvium is typically diffuse and temporary, but it can be distressing until the underlying cause is resolved.
Alopecia areata, an autoimmune disorder, is another prevalent cause of hair loss. The condition occurs when the immune system mistakenly attacks hair follicles, leading to sudden patchy hair loss on the scalp, face, or other areas of the body. Alopecia areata can range from small, round bald patches to complete loss of scalp and body hair in severe cases.
Nutritional deficiencies, particularly of vitamins and minerals like iron, zinc, biotin, and vitamin D, can also contribute to hair loss. These deficiencies often result from poor diet, restrictive eating habits, or underlying medical conditions that impair nutrient absorption. Correcting these imbalances through diet or supplementation can often restore normal hair growth.
Traction alopecia is another common condition caused by repetitive tension on the hair follicles from hairstyles such as tight ponytails, braids, or extensions. Over time, this constant pulling can damage hair follicles, leading to hair loss that may become permanent if the tension persists.
Lastly, medical conditions and treatments, including thyroid disorders, polycystic ovary syndrome (PCOS), and chemotherapy, can lead to significant hair loss. Hormonal imbalances or disruptions caused by these conditions can weaken hair follicles, while chemotherapy directly targets rapidly dividing cells, including those in hair follicles, leading to widespread hair shedding.
At Tarrant Street clinic we know the importance of making the right diagnosis when it comes to hair loss, so that the condition is managed appropriately. We might for example address nutritional deficiencies, use medication to balance hormones or use laser and /or light therapy. We might suggest other follicle stimulating treatments with PRP, PRF and or exosome therapy. We will make sure to carefully assess all patients and only advise suitable treatments as needed.
