Overview

Hair loss is the thinning of hair on the scalp. The medical term for hair loss is alopecia. Alopecia can be temporary or permanent. The most common form of hair loss occurs gradually and is referred to as "androgenetic alopecia," meaning that a combination of hormones (androgens are male hormones) and heredity (genetics) is needed to develop the condition. Other types of hair loss include alopecia areata (patches of baldness that usually grow back), telogen effluvium (rapid shedding after childbirth, fever, or sudden weight loss); and traction alopecia (thinning from tight braids or ponytails).

Types of Hair loss

Telogen Effluvium:
Telogen effluvium is a scalp disorder characterized by the thinning or shedding of hair resulting from the early entry of hair in the Telogen phase. It is a reactive process caused by a metabolic or hormonal stress or by medications.
(It is caused by Stress)

Androgenic Alopecia:
Androgenetic alopecia is the most common type of progressive hair loss. It is also known as male-pattern baldness, female-pattern baldness, or just common baldness. It affects about 50% of men over the age of 50, and about 50% of women over the age of 65. In women the severity varies, it may present as widespread hair thinning but in some cases it can lead to complete baldness.

Symptoms

Androgenic Alopecia:
Signs and symptoms of hair loss may include:Gradual thinning on top of head, Circular or patchy bald spots, Sudden loosening of hair, Full-body hair loss, Patches of scaling that spread over the scalp

Telogen Effluvium:
The main symptom of telogen effluvium is an increase in the amount of hair a person sheds. Someone may notice that more hair than usual is falling out when they wash or brush their hair. They may also find more hair in the drain or on their pillow.

Causes

Androgenic Alopecia:
Androgenetic alopecia is caused by a combination of genetic and hormonal factors. Dihydrotestosterone (DHT) is the main hormone responsible for androgenetic alopecia in genetically susceptible individuals. DHT causes scalp hair loss by inducing a change in the hair follicles on the scalp. The hairs produced by the affected follicles become progressively smaller in diameter, shorter in length and lighter in colour until eventually the follicles shrink completely and stop producing hair.

Telogen Effluvium:
Disturbances to the hair cycle can be caused by a number of triggers, including:

• Severe stress
• Poor diet
• Sudden weight loss
• Pregnancy and childbirth
• Menopause
• Certain drugs
• Underlying health conditions
• Surgery
• Metal toxicity

Prevention

Androgenic Alopecia:
Androgenetic alopecia is governed by androgens (Hormone),but you can follow a few hair hygiene tips to make your hair less likely to fall out. Avoid hairstyles that pull on the hair, Avoid high-heat hair styling tools,Don’t chemically treat or bleach your hair, Use a shampoo that’s mild and suited for your hair, Use a soft brush made from natural fibers.
