- Androgenetic Alopecia: The most common form caused by genetic and hormonal factors.
- Alopecia Areata: An autoimmune type causing localized, circular bald patches.
- Scarring Alopecia: Hair follicle loss due to skin scarring.
- Diffuse Alopecia: Hair thinning across the scalp, often due to stress or nutritional deficiencies.
