Can some shampoos cause hair loss?
Keep in mind the American Academy of Dermatology (AAD) doesn't list any shampoos, or shampoo ingredients, as common causes of hair loss. It's been suggested that both sulfates (cleansing agents) and formaldehyde (a preservative) can contribute to hair loss. To date, no research backs up these claims. Can shampoos make your hair fall out? Sulfur. It's important to avoid shampoos that contain sulfur, which could worsen your hair loss. “While sulfur allows shampoos to lather well, it also strips the oils from your scalp, causing your hair to dry out and break,"
