Trichorrhexis nodosa is a common hair shaft disorder characterized by thickenings or knots along the hair shaft where the hair becomes brittle and breaks easily. This disorder can affect both scalp hair and body hair and often results in visible hair breakage, which can affect hair growth and result in an unkempt appearance.
causes
Trichorrhexis nodosa can be caused by a variety of factors including:
- Mechanical Damage : Excessive brushing, rubbing, or other forms of mechanical manipulation of hair.
- Chemical Damage : Frequent use of hair treatments such as coloring, bleaching, perming, or straightening.
- Heat-related damage : Excessive use of hair dryers, straighteners, or curling irons.
- Environmental damage : Exposure to extreme weather conditions, such as strong sunlight or cold.
- Nutritional deficiencies : Lack of essential nutrients important for hair health, such as proteins , vitamins and minerals.
- Genetic factors : In some cases, Trichorrhexis nodosa can also be genetic.
Symptoms
- Hair breakage : The most noticeable symptom is hair breakage near the scalp or along the hair.
- Knots in hair : Visible knots or thickenings in the hair where it is brittle.
- Dry, brittle hair : Affected hair often feels dry and brittle and is difficult to style.
diagnosis
The diagnosis of trichorrhexis nodosa is usually made by visually examining the hair under a microscope to look for the characteristic knots or thickenings in the hair hair shaft to identify.
Treatment and management
Treatment for Trichorrhexis nodosa focuses on reducing hair manipulation and preventing damage:
- Gentle hair care : Using mild shampoos and conditioners, brushing gently and avoiding tight hairstyles.
- Reducing Chemical Treatments : Minimizing the use of hair dyes, bleaches, and perm chemicals.
- Avoiding Heat : Limiting the use of hair dryers, flat irons, and curling irons and using heat protectant products.
- Diet : Ensuring a balanced diet rich in proteins, vitamins and minerals to support hair health.
- Moisturizing : Regular use of moisturizing hair masks or oils to strengthen hair and improve its elasticity.
In some cases, it may be helpful to consult a dermatologist or trichologist for specific treatment recommendations and to rule out underlying health problems that could be contributing to hair breakage.
