Medication-induced hair loss can occur as a result of various factors, including:
Disruption of Hair Growth Cycle: Certain medications, such as chemotherapy drugs, interfere with the normal growth cycle of hair follicles, leading to hair loss.
Toxic Effects on Hair Follicles: Some medications may have toxic effects on the hair follicles, causing them to shrink or become damaged and resulting in hair loss.
Hormonal Imbalance: Medications that affect hormone levels, such as certain contraceptives, hormone replacement therapies, or androgen-blocking drugs, can contribute to hair loss by disrupting the hormonal balance necessary for healthy hair growth.
Specific medications that are believed to cause hair loss include acne medications, antibiotics, antidepressants, birth control pills, mood stabilizers, and hormone replacement therapy medication.
Individuals that are undergoing chemotherapy have also been known to lose their hair. This is due to the chemotherapy medication targeting cancer cells, but also damaging healthy cells. The hair may start to fall out rapidly within the first few weeks and continue to progress over the next few months
