Summary
Drug intake can cause hair loss, affecting hair follicles. While often reversible, some drug-induced alopecia may be permanent, requiring careful consideration of medication side effects.
Area of Science:
- Pharmacology
- Dermatology
- Toxicology
Background:
- Medications can impact hair growth, causing loss, altered shape, or color changes.
- Drug-induced hair loss is typically reversible, stemming from toxic effects on the hair follicle matrix.
Purpose of the Study:
- To review the mechanisms and clinical presentations of drug-induced hair loss.
- To highlight the relationship between specific drugs and various forms of alopecia.
Main Methods:
- Literature review of reported cases and established pharmacological effects.
- Analysis of drug-induced hair loss patterns, including telogen and anagen effluvium.
Main Results:
- Hair loss from drugs presents as telogen effluvium, anagen effluvium, or both.
- Discontinuation of anagen-prolonging drugs like minoxidil can also trigger telogen effluvium.
- Permanent alopecia is a rare but possible outcome of drug exposure.
Conclusions:
- The link between drug intake and hair loss is proven for a limited number of medications.
- Understanding drug-induced hair changes is crucial for patient management and treatment.
- Further research is needed to confirm causality for many reported drug-related hair issues.

01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
01:00Drug Toxicity: Overview
Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...
