The most common cause of hair loss is hereditary. This type is known as male pattern baldness or androgenetic alopecia. Other causes can include iron deficiency, thyroid issues, and autoimmune diseases. Local scalp problems like seborrheic dermatitis, fungal infections, or psoriasis can also contribute. At Bona Health, we focus on male pattern baldness and treat it with clinically proven, FDA-approved medications, including both pharmaceutical and non-pharmaceutical options.
