To respond, we must first comprehend hair washing.
As you wash your hair, shampoo's surfactants interact with water to remove debris and oils (via Byrdie).
Clean hair is great, but you may wash too much. Frequent washing might disturb your hair's microbiota.
Split ends, breakage, and dull hair may result.
Dominic Burg, hair biologist, microbiologist, and trichologist at Évolis Professional, tells Byrdie that too much lathering may lead to a bacterial overgrowth on the scalp, causing it to swell.
Not washing your hair sufficiently may lead to dandruff and irritation from oil and debris buildup, says Healthline.
