Lost weight and now noticing more hair in the shower? You are not imagining it.
Hair shedding after rapid weight loss, including weight loss from GLP-1 medications, is very common. When the body loses weight quickly, it can temporarily redirect nutrients away from hair growth, especially if protein, iron, vitamin B12, or vitamin D levels become depleted.
The good news is that in most cases, this type of hair loss is reversible once your weight stabilizes and nutritional deficiencies are corrected.
What to focus on if you are experiencing hair shedding:
• Meeting daily protein goals
• Eating green leafy vegetables
• Supplementing iron, vitamin B12, and vitamin D if needed
• Getting regular lab work
• Maintaining exercise to preserve muscle and support hair health
For some patients, rapid weight loss can unmask genetic male or female pattern hair loss, which is why early evaluation is important.
At Ziering Medical, we provide personalized hair loss consultations and advanced treatment options such as minoxidil, Kerafactors, and Z Factor Growth Injections to support hair regrowth and long-term hair health.
