Summary
Accurate hair loss diagnosis relies on patient history, clinical exams, lab tests, and scalp biopsies. Differentiating cicatricial from noncicatricial alopecia is key for effective treatment strategies.
Area of Science:
- Dermatology
- Trichology
Background:
- Hair loss (alopecia) affects numerous individuals, necessitating accurate diagnostic methods.
- Distinguishing between cicatricial and noncicatricial alopecia is crucial for appropriate management.
Purpose of the Study:
- To present a systematic diagnostic approach for various types of hair loss.
- To outline essential clinical and laboratory evaluations for diagnosing alopecia.
Main Methods:
- Review of diagnostic strategies for hair loss.
- Emphasis on patient history, global appearance assessment, and physical examination techniques (hair pull, tug, Hair Card, hair mount).
- Role of scalp biopsy in confirming diagnoses, particularly for cicatricial alopecia.
Main Results:
- Diagnostic accuracy is achieved through a combination of history, clinical examination, and investigations.
- Specific laboratory tests recommended include complete blood count, ferritin, thyroid-stimulating hormone, and vitamin D 25-hydroxy levels.
- Scalp biopsy is indispensable for diagnosing cicatricial alopecia.
Conclusions:
- A structured diagnostic process ensures accurate identification of hair loss causes.
- Comprehensive evaluation including targeted laboratory tests and biopsies guides effective therapeutic decisions.

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...
01:06Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:30Serum Laboratory Studies, Stool Test, Breath Test
Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...
01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
