Thinning hair refers to a gradual reduction in the density of hair on the scalp. This condition can affect both men and women and is often characterized by a widening part, receding hairline, or overall decrease in volume. Factors contributing to thinning hair include genetics, hormonal changes, and certain medical conditions. In some cases, thinning hair can be temporary and may improve with proper care or treatment. Common treatments include topical solutions like minoxidil, prescription medications, and lifestyle changes. Maintaining a healthy diet and managing stress can also support hair health and potentially slow down the thinning process.
