How do I prevent hair loss?

To prevent hair loss, focus on a healthy lifestyle with a balanced diet rich in vitamins like biotin, vitamin D, and iron. Avoid excessive heat styling or harsh chemical treatments, which can weaken hair. Reduce stress with relaxation techniques, as stress can contribute to hair loss. Be gentle when brushing and avoid tight hairstyles that can cause damage. If you notice significant hair thinning, consult a dermatologist to rule out underlying conditions like hormonal imbalances or scalp issues, and consider treatments.
