How Hair Loss Disorder Arises due to Medication Side effects

The normal human hair growth cycle consists of 3 phases: Anagen growth phase, Catagen transactional phase, and telogen resting phase. Various drugs can affect any of these phases. Mainly two types of scalp hair loss disorders arise due to interference in the natural growth cycle.

Telogen effluvium is a term refers to a most common type of drug-induced hair disorder characterized by hair shedding or thinning. It mainly involves premature interruption of hair growth with an early entry of anagen follicles into the resting phase, leading to a noticeable increase in hair shedding 2 to 3 months later.  Although there are many other factors (like stress, childbirth,  extreme fluctuation in weight, menopause, iron, vitamin-d deficiency, exposure to toxins etc) that can be responsible for this condition, medication side-effect is on top of all. People who are taking above-mentioned medications for more than 6 months are at more risk. You may not experience full baldness or lose all hairs in this but hairs become noticeable thin.

Anagen effluvium refers to hair loss that occurs during the growth phase (anagen phase) of the hair cycle. It inhibits the matrix cell growth and fractures the hair shaft, which results in almost full baldness in just a few days. The extent of hair loss in Anagen Effluvium is relatively much higher than in Telogen Effluvium. In this problem, hair loss is not just limited to the scalp, but it extends to the face and body too. Medicines & drugs used in chemotherapy ( or chemo) for cancer treatment is mainly responsible for Anagen effluvium. Other medical conditions or medication responsible include pemphigus vulgaris, radiation therapy, endocrine diseases, trauma, pressure, cicatrizing disease and alopecia areta and exposure to certain chemicals like boron, arsenic or thallium.
