Hair loss is clinically known as Alopecia. The normal hair growth cycle is divided into four stages: anagen(growth), catagen (involution), telogen (resting), and exogen (shedding of hair).
Did you know? Shedding 100 strands in a day is normal for hair loss.
The most common type of hair loss in both men and women is called androgenetic alopecia, or female (or male) pattern hair loss. Androgenetic alopecia involves the action of hormone androgens which plays important role in regulating hair growth. Excessive activation of androgen shortens the hair’s growing phase thereby causing the hair follicle to shrunken and making it harder to grow.
In men, hair often begins to grow less at the hairline on the forehead. While women do not usually go bald but have hair thinning predominantly over the top and front of the head.
Many different conditions can lead to hair loss, including:
Genetic: Male or female pattern baldness or androgenetic alopecia is a genetic condition due to excessive response of androgens which affects nearly half of males and females.
Pollution: The pollutants including particulate matter, dust, smoke, nickel, lead and arsenic, sulfur dioxide nitrogen dioxide, ammonia and polycyclic aromatic hydrocarbons (PAH) can settle on the scalp and hair across the epidermis then migrate into the dermis and through the hair follicle channel, leading to oxidative stress and hair loss.
Hormonal changes and medical conditions: Signalling of thyroid hormone play a role in skin proliferation and hair growth. Hence medical conditions such as thyroid disease often seen with hair loss problems.
Radiation therapy to the head/ chemotherapy: Chemotherapeutics and high-dosage radiotherapy to the head and neck can cause damage to hair follicles.
Over-supplementation of some nutrients in absence deficiency may result in multiple toxicities, while over-supplementation of certain nutrients including vitamin A and selenium may actually result in hair loss.
Apart from that, many more factors such as stress, medications, nutritional deficiency, and vigorous styling can affect hair growth, leading to hair loss.
Below are nutrients that you need for healthy hair:
Here are few tips to prevent hair loss:
- Practicing a healthy and balanced diet
- Be gentle with your hair
- Consult the doctor about medications and supplements that might cause hair loss
- Protect your hair from sunlight and other sources of ultraviolet light
- Stop smoking
- Use the cooling cap to reduce the risk of losing hair during chemotherapy
