Hair Trace Mineral Analysis (HTMA) is an increasingly popular tool used to evaluate the mineral content of hair. By analyzing hair samples, practitioners can gain insights into an individual’s metabolic processes and nutritional status. This method has shown promise, particularly in managing conditions such as autism and ADHD, where underlying nutritional imbalances may play a significant role. In this article, we will explore the principles of HTMA, its application in autism and ADHD, and the benefits and challenges associated with this approach.
