2. The Maintenance Formula: For my routine washes, I reach for the maintenance shampoo, which features a pH 4.0 – 5.0 formula (or sometimes cited as 4.5 to 5.5). This is designed with an optimized pH to ensure daily cleansing is gentle. It is essentially a cleansing shampoo with an optimised pH level that keeps my color vibrant and my strands feeling smooth.
