Hello, I'm an expert in the field of dermatology with a focus on hair and scalp health. There are numerous factors that can contribute to hair loss, and it's important to understand that hair shedding is a natural part of the hair growth cycle. However, excessive hair loss can be a sign of underlying issues. Here are some common causes of hair loss:


1. Genetics: Hereditary hair loss, also known as androgenetic alopecia, is the most common cause.

2. Hormonal changes: Conditions like polycystic ovary syndrome (PCOS), pregnancy, or menopause can lead to hair loss.

3. Nutritional deficiencies: Lack of essential nutrients like iron, protein, vitamin D, and biotin can cause hair to fall out.

4. Stress: Physical or emotional stress can lead to a type of hair loss called telogen effluvium.

5. Medications: Certain drugs, including those used for cancer, arthritis, depression, heart disease, and high blood pressure, can cause hair loss as a side effect.

6. Hazardous hair care practices: Excessive use of heat styling tools, chemical treatments, and tight hairstyles can damage hair and lead to breakage.
7.
Autoimmune diseases: Conditions like alopecia areata occur when the immune system attacks hair follicles.
8.
Infections: Fungal or bacterial infections on the scalp can cause hair loss.
9.
Surgical procedures: Major surgery or severe illness can trigger hair loss.
10.
Severe medical conditions: Diseases like anemia, cancer, and thyroid disease can lead to hair loss.

It's crucial to consult with a healthcare provider or a dermatologist if you're experiencing significant hair loss to determine the cause and appropriate treatment.
