Hair breakage due to bleaching: what to know

Bleaching removes natural pigment by changing the structure of the hair fibre. The cuticle can become rougher and the inner shaft less resilient, especially after repeated sessions, overlapping product onto already lightened lengths, or leaving product on too long. Hair may snap at different points, feel rough or stretchy when wet, and show split or frayed ends. Breakage is different from shedding: the hair has broken along its length rather than leaving the scalp with a club-shaped root. The scalp itself may still look normal.

Pause bleaching and avoid overlapping lightener onto fragile lengths. Use a gentle shampoo when needed, conditioner after washing, and a wide-tooth comb on damp hair, starting at the ends. Blot rather than rub, limit hot tools, and use the lowest practical heat with protection. Loose styles reduce pulling while the hair recovers. A trim can remove split ends, but it cannot repair a broken section back together. A dermatologist or experienced hair professional can examine the pattern and help plan safer spacing and application if you still want chemical services.

Arrange a dermatology assessment if breakage continues after stopping bleaching, if there are smooth or sharply defined areas of hair loss, or if the scalp is painful, blistered, crusted, swollen, or intensely itchy. Sudden loss with redness or scaling deserves prompt attention because a scalp disorder can coexist with cosmetic damage. Persistent pulling-related loss may be related to Traction Alopecia, while marked scaling and broken hairs can occur with Scalp Ringworm; these need different treatment from hair-shaft conditioning.

Could this be shaft breakage, shedding, or both? Does the scalp show inflammation or infection? Should I stop all lightening for now? Which cleansing and detangling routine suits my hair texture? If chemical treatment is resumed later, how can application avoid previously lightened hair?
