Overview
- Trainee trichologist Clodagh Egan (@clodaghhaircare) says bacteria, dead skin and dirt on unwashed brushes can irritate hair follicles over time.
- She characterizes hair loss from this issue as occurring in extreme cases and advises against keeping brushes dirty.
- Egan also links dirty brushes to greasy hair because residue transfers from hair to brush and back during washing.
- Her cleaning method involves an overnight soak in water with a detox shampoo, baking soda and regular shampoo, followed by air-drying.
- She suggests washing brushes about monthly if you own many or weekly if you have few, while the NHS notes many other causes of hair loss.
