Causes of Frizzy, Brittle Hair

The cuticle is the hair’s outer protective layer. Repeated bleaching, colouring, relaxing, perming, hot tools, rough towel-drying, and brushing wet hair can lift or weaken it. Moisture then leaves unevenly, making strands swell and look frizzy; weakened fibres snap, split, or feel rough. Chlorinated or salty water and dry air can add stress. If the change is widespread, persistent, or accompanied by scalp symptoms, nutrition, thyroid function, medicines, or a hair disorder may also need consideration.

Pause overlapping chemical services and lower heat settings. Use conditioner through the lengths, detangle gently from the ends upward, and avoid tight styles and elastic bands that catch the fibre. Pat rather than rub hair dry, and protect it from sun, pool water, and repeated friction. A clinician can assess persistent fragility; Hair Supplement Therapy should be considered only after discussing whether a deficiency or another cause is present.

Seek assessment for sudden breakage, thinning at the scalp, smooth patches, scaling, pain, redness, or intense itching. Arrange care when hair changes continue despite gentler handling, or when fatigue, dietary restriction, weight change, or a new medicine coincides with the problem. Early examination helps distinguish shaft damage from hair shedding or scalp disease.

Ask: Is this shaft breakage or shedding from the root? Could my scalp or a medicine be contributing? Do I need blood tests before taking supplements? Which styling practices should I stop, and what recovery signs should I watch for?
