4. Scalp and Skin Conditions

Your scalp health directly affects your hair. Issues like dandruff, fungal infections, psoriasis, or dermatitis can weaken hair roots and cause shedding. In some cases, inflammation damages the follicles, leading to patchy hair loss. Treating the scalp condition early can prevent long-term damage.

5. Medical Conditions and Medications

Certain illnesses can contribute to hair loss. Autoimmune disorders such as alopecia areata cause the immune system to attack hair follicles, resulting in sudden patches of hair loss. Additionally, medications for conditions like cancer, high blood pressure, depression, or arthritis may list hair loss as a side effect.

6. Genetics and Aging

Sometimes, hair loss is simply part of your genetic makeup. Pattern hair loss, also known as androgenetic alopecia, affects both men and women as they age. It usually appears gradually and follows a predictable pattern, such as a receding hairline or thinning at the crown.
