What happens with Hair Weathering (Trichorrhexis Nodosa)?

In Hair Weathering (Trichorrhexis Nodosa), the hair shaft develops weak points or nodes, leading to fraying, splitting, and eventual breakage. Excessive grooming, harsh hair treatments, or environmental factors cause the damage, resulting in hair that cannot grow to longer lengths.

What are the symptoms?

Hair that is prone to breaking and splitting
Rough texture and lack of smoothness in the hair
Visible white nodes or weak points along the hair shaft
Difficulty growing hair to longer lengths due to breakage

Key facts

Hair Weathering is more common in individuals with dry, brittle hair
Chemical treatments like dyeing, perming, or straightening can exacerbate the condition
The condition is not typically associated with systemic health issues
Proper hair care and minimising damage can improve the condition significantly

What triggers Hair Weathering?

Chemical treatments: Dyeing, perming, relaxing, or straightening the hair
Heat styling: Repeated use of hairdryers, straighteners, or curling tongs
Mechanical damage: Aggressive brushing, combing, or tight hairstyles
Environmental factors: Sun exposure, chlorine from swimming pools, and dry conditions

Weathering is one of the most common causes of hair breakage we see at The Hair Centre. While it's not a medical disorder, it can significantly affect hair health and confidence. With the right approach — gentle care, hydration, and protective styling — it's entirely manageable.

Can Hair Weathering be cured?

Hair Weathering cannot be permanently "cured" as it results from cumulative damage to the hair shaft, which cannot repair itself. However, it can be effectively managed and prevented by minimising harsh treatments, using gentle hair care products, and adopting protective hair practices. With proper care, new hair growth remains unaffected and the overall condition of the hair can significantly improve.
