Hair loss during brushing may result from deficiencies in nutrients such as protein, minerals, and vitamins. It may also be associated with hormonal imbalances or endocrine disorders. Additionally, factors such as low mood, high stress levels, sleep deprivation, and excessive sebum production can also contribute to hair shedding while brushing.
