A complete blood count (CBC) can check your overall health, particularly for anemia, which may contribute to hair thinning. Testing your iron and ferritin levels is also important, as low iron can affect hair growth. Thyroid function tests measure TSH, T3, and T4 levels to determine if an underactive thyroid (hypothyroidism) is behind the hair loss. Checking your vitamin D levels is crucial too, since low vitamin D can cause hair shedding. Hormonal imbalances, especially related to testosterone and DHT, may also be contributing factors. Lastly, nutrient deficiency tests, such as zinc levels, can reveal if a lack of essential nutrients is causing your hair loss.&nbsp;<br> <br> These tests are important because they can pinpoint the exact cause of your hair loss, saving time and effort on treatments that may not work. Understanding the underlying issue allows for more effective and personalized treatment plans, whether it's supplementing vitamins, correcting hormonal imbalances, or addressing thyroid problems. Early detection of these deficiencies can also prevent further hair loss and help promote healthier hair growth over time.</b></span><div><b></b></div></div> <div><span style="font-weight: bolder; font-size: 18px;">If you’re experiencing hair loss, a blood test can help identify possible causes.
