The document summarizes a seminar on alopecia that was held on April 5, 2005. It was organized by the Department of Dermatology at MMCH and Renata Limited. The seminar featured speakers who discussed the structure of hair and hair follicles, the hair cycle, types of alopecia including alopecia areata, its clinical features, histology, differential diagnosis, and treatment options. Alopecia areata is an autoimmune condition characterized by patchy non-scarring hair loss that typically affects the scalp but can also involve other hairy areas of the body.
Hair is composed of protein fibers that grow from follicles in the skin. Each hair strand consists of three layers - an inner medulla, middle cortex that provides color and strength, and outer cuticle. Hair grows in cycles with three phases - growth (anagen), transition (catagen), and resting (telogen). Common hair problems include dandruff caused by dry skin, fungus or products and scalp psoriasis caused by a faulty immune system leading to rapid skin cell growth. Shampoo formulations include surfactants, conditioning agents and special additives to clean and treat hair and scalp issues.

Structure of hair & hair growth cycle, dental problemsHemant Khandoliya
This document discusses biological aspects of cosmetics, focusing on hair and common oral cavity problems. It describes hair structure including the hair follicle and shaft. The three phases of the hair growth cycle are outlined as anagen, catagen, and telogen. Common oral problems discussed include bad breath, gum disease, tooth decay, oral cancer, and leukoplakia. Causes and treatments are provided for each problem.
This document discusses hair structure and the hair growth cycle. It notes that hair grows from follicles in the dermis and is composed mainly of keratin protein. Hair has several layers - the medulla, cortex, and cuticle. The hair growth cycle consists of the anagen (growth), catagen (regression), telogen (rest), and exogen (shedding) phases. During anagen, hair grows rapidly from the hair bulb. Catagen is a transition phase where growth stops. Telogen is a resting phase where the hair remains until it sheds during exogen. The document also briefly discusses formulations for different types of shampoos.
The document discusses the benefits of exercise for both physical and mental health. It notes that regular exercise can reduce the risk of diseases like heart disease and diabetes, improve mood, and reduce feelings of stress and anxiety. Staying active also helps maintain a healthy weight and keeps muscles, bones and joints healthy as we age.
Grading Staging in Androgenetic Alopecia (Male Pattern Baldness) by AseemDr. Aseem Sharma
This document discusses grading scales used to assess androgenetic alopecia, or male and female pattern baldness. It describes several scales, including the Norwood-Hamilton scale from 1970 which grades male pattern baldness into stages I through VII. The Bouhana scale from 1976 is a modified version of the Norwood-Hamilton scale that allows for more rapid assessment. For female pattern hair loss, scales discussed include the Ludwig scale from 1977, Olsen scale from 1999, Savin scale from 1994, and Gan-Sinclair scale from 2006, with the Norwood-Hamilton scale also sometimes used. The scales are used as a basis for grading hair loss patterns and assessing treatment approaches.

The document discusses different types of hair loss including alopecia, androgenetic alopecia in men and women, traction alopecia, and their causes and treatments. It describes the hair growth cycle and tests used to evaluate hair loss. Common treatments for androgenetic alopecia include minoxidil, finasteride, and spironolactone depending on the patient's sex and symptoms. Traction alopecia is caused by hairstyles that pull on hair and can be prevented by less tight styling.
This document discusses hair science and the classification of alopecia. It begins by covering hair anatomy and the hair cycle process. It then classifies different types of alopecia as either noncicatricial (non-scarring) or cicatricial (scarring). One type covered in detail is alopecia areata, which is described as a chronic inflammatory disorder characterized by patchy hair loss without scalp atrophy. The etiology, clinical features, investigations, histopathology and prognosis of alopecia areata are summarized.
The document discusses various types of hair loss including:
- Androgenic alopecia (male and female pattern baldness) which is influenced by hormones and genetics.
- Alopecia areata which causes patchy hair loss and may result in complete baldness. It often affects children and young adults.
- Telogen effluvium which is a temporary form of hair thinning caused by a large number of hairs entering the resting phase at the same time.
- Treatments discussed include minoxidil, finasteride, hair transplants, and targeting the underlying cause for conditions like telogen effluvium.

The document provides information about alopecia or hair loss, including:
- There are approximately 100,000 hair follicles on the average human scalp.
- Alopecia universalis is the most severe form and results in a total loss of hair on the entire body, including eyebrows and eyelashes.
- Hair is made up primarily of the protein keratin.
- The three stages of the hair growth cycle are anagen (growth phase), catagen (transition phase), and telogen (resting phase).
- Fetal body hair is known as lanugo hair.
Hair follicles grow at an angle with the major part developing from epithelial cells. The upper follicle is permanent while the lower regenerates with each hair cycle. Hair follicles contain the hair bulb with dermal papilla, hair matrix cells, inner and outer root sheaths, and the hair shaft. The hair cycle consists of growth (anagen), involution (catagen), and resting (telogen) phases over 3-7 years. During anagen, hair grows rapidly from matrix cells. Catagen is a short transition phase and telogen is a resting phase before the next anagen.
The document summarizes key aspects of scalp and hair anatomy. It describes the layers of the scalp, including skin, connective tissue, the aponeurotic layer, loose connective tissue, and peri-cranium. It outlines the blood supply, nerve supply, muscles and growth cycle of hair. Finally, it discusses various conditions that can affect the scalp and hair, such as sebaceous cysts, telogen effluvium, discoid lupus erythematosus, and non-scarring hair loss.
Hairs project from the body's surface and come in a variety of lengths, widths, and growth rates. They serve protective, sensory, and social functions. Hair growth occurs in cycles of anagen, catagen, telogen, and exogen phases. Common types of hair loss include alopecia areata (patchy bald spots), androgenetic alopecia (male or female pattern baldness), and postpartum alopecia. Hair loss can be caused by physical or emotional stress, diet, hormones, medical conditions, or hair manipulation. Treatments include medications, lifestyle changes, and hair transplants. More research seeks to fully cure types of alopecia.

HAIR Anatomy- Basic structure and function.pptxDrPabitraKumar
Hair follicles go through cyclic phases of growth (anagen), regression (catagen), and rest (telogen). During anagen, the hair follicle grows rapidly reaching its maximum length over 2-7 years. Then in catagen over 2-3 weeks, the lower follicle regresses and the dermal papilla condenses and moves upwards. Telogen lasts around 3 months with the hair in a club-like resting phase before the next anagen phase. This cyclic regeneration of the hair follicle results in the continuous growth and shedding of hair.
This document discusses the structure and growth cycle of hair. It describes hair as being made up of keratin and composed of three main parts: the hair root, shaft, and follicle. The hair follicle contains the dermal papilla and hair bulb. Hair grows in a cycle with three phases: anagen (growth), catagen (transition), and telogen (resting). During the anagen phase, hair grows about 1 cm per month from the dermal papilla. The catagen and telogen phases allow the follicle to rest and prepare for the next growth cycle.
This document summarizes information about hair and hair loss disorders. It discusses the structure and growth cycle of hair follicles. There are three main types of hair: lanugo, vellus and terminal hair. Hair loss disorders can be localized or diffuse, scarring or non-scarring. Common causes of hair loss include alopecia areata (autoimmune), telogen effluvium (temporary shedding), and androgenic alopecia (male or female pattern baldness due to genetics and hormones). Treatment depends on the specific condition but may include topical medications, immunotherapy, or hair transplants.

This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is a summary of Pneumothorax:
Pneumothorax, also known as a collapsed lung, is a condition that occurs when air leaks into the space between the lung and chest wall. This air buildup puts pressure on the lung, preventing it from expanding fully when you breathe. A pneumothorax can cause a complete or partial collapse of the lung.

structures derived from invaginations of
epidermis and project out from most of
the body surface.

There are four phases-There are four phases-
1.1. Anagen :Anagen : growing phase.growing phase.
2.2. Catagen:Catagen: involuting phase.involuting phase.
3.3. Telogen :Telogen : resting phase.resting phase.
4.4. Exogen :Exogen : hair shedding phase.hair shedding phase.
18. ANAGEN (GROWING PHASE)
Last for about 1000 days.
Follicular cells grow, divide and become
keratinized to form growing phase.
A darkly pigmented portion is evident just
above the hair bulb.
19. CATAGEN (INVOLUTING PHASE)
Lasts for about 10 days.
Scalp hairs show a gradual thinning and
decrease of the pigment.
Melanocytes cease producing melanin.
Matrix keratinocytes abruptly cease
proliferating so that lower follicle involutes
and regresses.

21. EXOGENEXOGEN (HAIR SHEDDING PHASE)(HAIR SHEDDING PHASE)
Recently added phase.
The term describes relationship between hair
shaft and base of telogen follicle.
Hairs can be retained for more than one
cycle.
Shedding phase is most likely independent of
anagen and telogen.

23. Greying of hair – due to decreased
number and activities of melanocytes.
Vitiligo – due to destruction of
melanocytes.
