Start skin and hair care during weight loss to prevent face sagging and hair loss

Rapid weight loss can cause hair loss, facial sagging and an aged look. A dermatologist says skin and hair care should begin with weight loss, not after. More than 60% of patients undergoing rapid weight loss report these effects, which begin once 5-10% of body weight is lost. Any accelerated slimming—restrictive diets, bariatric surgery or illness—can trigger it. Exercise preserves muscle but does not treat skin laxity. Hair loss typically appears weeks after weight loss begins. Self-prescribed vitamins may be unnecessary or harmful; moisturizing creams do not reach the collagen layer. Treatments may include collagen stimulators or lasers, requiring individual assessment.
