🚨💙REMOVE MINERAL BUILD UP!💙🚨 . My favorite product is ColorProof’s Pre-Tox spray. Living in Upstate New York we have very hard water and the pre-tox spray is great to use to remove the mineral buildup! After using the Pre-Tox just once multiple people said how my blonde was brighter! I suggest anyone with hard water to use pre-tox! - Kierah from A&A Clifton Park
