Hair brushing should be __________.

Hair brushing should be avoided if the scalp is irritated because brushing can exacerbate the irritation and cause discomfort or further damage to the scalp. When the scalp is inflamed, sensitive, or has any kind of injury, brushing can lead to increased pain and even the risk of infection or further irritation. It's important to be gentle and kind to the scalp during such times to promote healing rather than exacerbate any existing issues.

In contrast, encouraging brushing before shampooing, stimulating blood flow through vigorous brushing, or limiting brushing to once a week may not think about the individual needs of the hair and scalp. Regular brushing can indeed help distribute natural oils and remove dirt, but it should always be done with care, especially if there are any existing scalp conditions. The health and comfort of the scalp should always take precedence in hair care practices.
