Step-by-step explanation:
Trichorrhexis nodosa is a condition characterized by the presence of lumps or swelling along the hair shaft. It occurs due to weakening of the inner layer of the hair shaft, known as the cortex. This weakening can be caused by various factors such as chemical damage, heat styling, grooming practices, nutritional deficiencies, and certain medical conditions.
For example, excessive use of hot hair tools like straighteners and curling irons can lead to trichorrhexis nodosa. In addition, certain medical conditions like hypothyroidism, iron deficiency anemia, and certain genetic disorders can also contribute to the development of this condition.
Trichorrhexis nodosa can result in hair breakage, split ends, and overall weakened hair. Treatment options for this condition include avoiding heat styling, minimizing chemical treatments, improving nutrition, and using hair care products specifically designed to strengthen and nourish the hair.
