Hair loss

Hair loss, medically termed alopecia, can have various causes, ranging from genetic factors to underlying health conditions. Here are some common reasons for hair loss:

 

1. Genetics (Androgenetic Alopecia): This is the most common cause of hair loss and is often referred to as male-pattern or female-pattern baldness. It's hereditary and can affect both men and women. In men, it typically presents as a receding hairline and thinning on the crown, while in women, it usually causes overall thinning of the hair.

 

2. Hormonal Changes: Hormonal changes due to pregnancy, childbirth, menopause, or thyroid problems can lead to temporary or permanent hair loss.

 

3. Medical Conditions: Certain medical conditions such as alopecia areata (an autoimmune disease causing patchy hair loss), scalp infections like ringworm, and trichotillomania (a psychological disorder involving compulsive hair pulling) can result in hair loss.

 

4. Medications and Treatments: Some medications used for cancer, arthritis, depression, heart problems, and high blood pressure can cause hair loss as a side effect. Chemotherapy and radiation therapy are also known to cause hair loss, although it is usually temporary.

 

5. Stress: Severe emotional or physical stress can lead to a type of hair loss called telogen effluvium. This condition causes a large number of hair follicles to enter the resting phase simultaneously, leading to significant shedding.

 

6. Nutritional Deficiencies: Deficiencies in certain nutrients, such as iron, protein, vitamins (particularly B vitamins), and minerals like zinc and selenium, can lead to hair loss.

 

7. Age: As people age, the rate of hair growth slows down, and hair follicles may shrink, leading to thinner and more fragile hair.

 

8. Traction Alopecia: This type of hair loss occurs when the hair is repeatedly pulled or subjected to tension from tight hairstyles like ponytails, braids, or extensions.

 

9. Chemical Damage: Overuse of hair styling tools (like straighteners and curling irons) or harsh chemical treatments (like dyes, relaxers, and perms) can damage the hair and cause it to break off or fall out.

 

10. Poor Scalp Health: Conditions like dandruff, psoriasis, and seborrheic dermatitis can affect the health of the scalp and contribute to hair loss. It's essential to consult a healthcare professional or a dermatologist if you're experiencing significant or sudden hair loss to determine the underlying cause and appropriate treatment.
