Q: What can I do for hair that is thinning and breaking and has absolutely no body due to a low thyroid? I have been on thyroid medicine for two years. I used to have full, bouncing hair. Now it's limp and won't even hold a curl. It feels dry all the time.
 
A: I completely understand how frustrating this experience must be for you. Hair changes related to thyroid conditions are common, and you're definitely not alone in dealing with this challenge. The good news is that there are several approaches you can take to address these issues, though it will require patience and likely some adjustments to your current treatment plan.
 
The first and most important step is to have a conversation with your doctor about your ongoing hair problems. Even though you've been on thyroid medication for two years, your current symptoms suggest that your thyroid levels may not be optimally managed yet. Many people assume that being on medication means their thyroid is properly treated, but the reality is that finding the right dosage and sometimes the right type of medication can take time and fine-tuning.
 
It's also worth noting that the hair problems you're experiencing could be related to the medication itself, though this is less common. Some people experience hair loss as a side effect of certain thyroid medications, particularly when starting treatment or changing dosages. Your doctor can help determine if this might be contributing to your situation.
 
In terms of hair care while you're working on the underlying thyroid management, gentle treatment is absolutely essential. Your hair is likely more fragile than it used to be, so harsh chemicals, excessive heat styling, and aggressive brushing can make the problem worse. Use a sulfate-free, moisturizing shampoo and always follow with a protein and moisture-rich conditioner. Consider using leave-in treatments or hair masks once or twice a week to provide extra nourishment.
 
When your hair is wet, it's at its most vulnerable state, so be extra gentle. Use a wide-tooth comb to detangle, starting from the ends and working your way up to the roots. Consider sleeping on a silk or satin pillowcase to reduce friction and breakage while you sleep.
 
If your doctor agrees that it's appropriate, a body wave or gentle perm might help give your hair more volume and texture. However, make sure your hair is in reasonably good condition before considering any chemical treatments, as damaged hair may not respond well to processing.
 
It's crucial to have realistic expectations about the timeline for improvement. Hair grows slowly, typically only about half an inch per month, and it can take several months of proper thyroid management before you start seeing significant improvements in new hair growth. The hair that's currently damaged may need to grow out and be replaced with healthier hair, which is a gradual process.
