The best way to tell if the hair root is dead is to look for signs of shedding. If you are noticing an increase in the amount of hair coming out when you brush or comb your hair, or if you are finding more hair strands in the shower drain, then the hair root may be dead. Additionally, if you are noticing that your hair is thinning or that it is not growing as much as it used to, then the hair root may be dead.
Another way to tell if the hair root is dead is to look at the scalp. If the scalp appears dry and flaky, or if there is irritation, redness, or scaling, this can indicate that the hair root is dead. Additionally, if you notice any patches of baldness, this is a sign that the hair root is dead.
Finally, if you have tried a variety of treatments to promote hair growth and nothing is working, then this could be a sign that the hair root is dead. It is important to consult with a dermatologist if you are experiencing any of these signs, as they will be able to determine the underlying cause and provide the best treatment options.
