What Are The Medical Causes Of Hair Loss?

  • Genetic hair loss (Pattern baldness in male in female) – Pattern baldness in men and women is known as androgenetic alopecia. It usually affects the top portion of scalp, which results in thinning and receding hairline, hair loss at crown and temple; also leading to partial baldness. Male pattern hair loss is caused due to genetics and a male hormone called dihydrotestosterone (DHT) while causes of female androgenetic alopecia are yet not known. It can be treated effectively with PRP and topical medications.
  • Diffuse hair loss (telogen effluvium) – It is a hair condition which leads to reduction of hair volume and excessive hair shedding. This is a temporary hair loss that occurs due to diffuse shedding of hair in resting phase when the body experiences a shock. When such a thing happens, an individual tends to lose nearly 100-125 hair per day. Due to this, nearly 70% of active hair also known as anagen hair gets into the zone of resting known as telogen phase, which results in a sizeable quantity of hair being pushed out of the scalp. It can be treated with PRP and medications.
  • Hair loss due to autoimmune disorders – This occurs when the body itself attacks and destroys healthy body tissues. This may occur in people with certain genes, which makes them prone to such kinds of autoimmune disorders.
    • Alopecia areata (Patchy hair loss) – It is a systemic autoimmune disorder and an acquired skin disease which affects all areas of hair on the body as disturbed immune system of the body causes destruction of the anagen hair follicles. Clinical methods like trichoscopy can done by an expert dermato-trichologist, to diagnose the condition. It occurs equally in both males and females.

    • Hashimoto disease – It is also an autoimmune disease where your immune system attacks your thyroid glands. Too much or too little thyroid hormone both can result in hair loss. Too little thyroid hormone in the body causes improper digestion of the necessary proteins for hair growth.
  • Hair loss due to hormonal disorders – Hormones are the most crucial chemicals in our body and any disorder in them can cause several ailments. Hormonal fluctuations usually occur during menopause, perimenopause, PCOS, endocrine and thyroid problems.
    • Thyroid hair loss – Both hyperthyroidism and hypothyroidism can result in hair loss. It is more diffuse kind of hair fall due to thyroid problems. Usually the hair grows back after thyroid problem is treated.
    • Oestrogen – Too much of this hormone can cause hair thinning. Especially during and post pregnancy, this hormone surges in the body thus causing hair loss.
    • DHT – Excess of DHT in the hair follicle causes hair loss. It is triggered by excess of hormone testosterone in the body, or reduced progesterone hormone in the body, as both these cases lead to DHT surge.
    • PCOS hair loss – Polycystic ovarian syndrome can cause hyperandrogenism where the body begins to produce too many androgens which are the male hormones. Sometimes the hair follicles are too sensitive to androgens thus, it reduces the hair growth on scalp.
  • Scalp infection – There are certain scalp infections which trigger hair thinning and result in hair loss eventually. These include
    • Psoriasis – It is a condition where the skin cells turn red, scaly and silver patches grow, which are due to the immune system of the body and begin to form plaques on the skin surface. When this condition affects the scalp, it results in temporary hair loss.
    • Ring worms – It is a fungal infection that causes hair loss when it occurs on the scalp.
    • Folliculitis – It causes the inflammation of hair follicles that causes the hair to fall. In severe cases of folliculitis the hair follicles are destroyed permanently resulting in hair loss.
    • Seborrheic dermatitis – It is also an inflammatory condition which causes the skin to become oily too. Androgen steroids can trigger them and they result in excess sebum and yeast infection thus causing scalp skin irritation and pain.
    • Piedra – It occurs when hair fibres are infected due to fungal infection. They develop hard nodules on hair fibres. This results in diffuse or patchy hair loss.
    • Dandruff – Dry skin and some infections like seborrheic dermatitis can cause dandruff or flaky scalp skin. In some cases if dandruff is left untreated it can lead to temporary hair loss
  • Chemotherapy hair loss – It is the process to slow down cancer cells in the body. Since the drugs in chemotherapy attack cells in the body like cancer cells, they even kill hair follicle cells thus causing hair loss. However, it may not be a permanent situation as hair grows back after 3-6 months post chemotherapy.
  • Hair loss due to drugs – Certain kinds of medications can cause hair loss in some people. These kinds of alopecia include anagen effluvium that affects the hair in growth phase and telogen effluvium that affects hair in rest phase or bulb hair. Some anti-coagulants, oral contraceptive pills, anti-hypertensive, NSAID’s and anti-depressants can trigger hair loss due to telogen effluvium.
  • Diabetes and hair loss – People with diabetes are more prone to alopecia areata, where the body’s immune system attacks hair follicles and causes patchy hair loss not just on scalp but other parts of the body too.
