What is the term for hair that is susceptible to breakage, also known as brittle hair?

The correct term for hair that is susceptible to breakage, commonly referred to as brittle hair, is indeed "fragilitas crinium." This condition signifies that the hair structure is weakened, leading to increased fragility and a propensity for the hair to break easily. Fragilitas crinium can result from various factors, including excessive heat styling, chemical treatments, or lack of moisture.

Understanding this term is essential for hair care professionals, as it helps them to identify and address issues related to hair health. Recognizing signs of fragility can guide appropriate treatment options and product recommendations to strengthen and repair the hair.

In contrast, trichorrhexis refers to a specific hair shaft defect characterized by a bulbous swelling and subsequent breakage. Telogen effluvium is a temporary hair loss condition triggered by stress or hormonal changes, while psoriasis is a skin condition that can affect the scalp but is not specifically related to hair breakage. Each of these terms pertains to different aspects of hair and scalp health, highlighting the importance of understanding various hair conditions in the beauty industry.
