There is no consistent evidence that Dove shampoo causes hair loss. However, some formulations of Dove shampoo contain sulfates, which are known to strip the hair of its natural oils and can lead to hair loss. Additionally, Dove is currently under investigation for the use of DMDM Hydantoin and Sodium Lauryl Sulfate in some of its shampoos. These ingredients are potentially harmful and may cause irritation and dryness, especially for those with dry and/or sensitive scalps. It is important to check the ingredient list of the product before purchasing it. If you are already experiencing hair loss or have a sensitive scalp, it may be best to avoid Dove shampoos with sulfates or potentially irritating extracts and oils.
