I understand how frustrating it is to deal with hair breakage, especially when supplements like Follihair and Xtraglo haven't helped. Trichorrhexis nodosa is often triggered by physical or chemical trauma to the hair shaft, or sometimes underlying health conditions. First, try to minimize heat styling, harsh chemicals, and vigorous brushing to protect the hair. I highly recommend consulting a dermatologist. They can perform a scalp examination and check for underlying issues like thyroid imbalances or iron deficiency. They may suggest specific medical therapies, such as topical minoxidil if there is concurrent hair loss, or specialized hair-strengthening treatments.
