New Wash worked great for years and suddenly seems less effective. Why?

Hairstory has not changed the formula of any New Wash, so when a longtime customer experiences a shift there is almost always an external explanation. The most common causes: Water: A change in water source (moved, seasonal municipal shifts, hard water) can affect how New Wash rinses. Products: A new styling product, heat treatment, or anything that foams can restart the disruption cycle. Physical changes: Hormones, stress, diet, seasonal shifts, medication, pregnancy - the scalp responds to all of these. Ask: same formula as before? Any water situation changes? New products added? Any major life changes? Most longtime customers who experience a shift find the answer in one of these variables. If troubleshooting doesn't resolve it, the return policy covers exchanges even for repeat purchases.
