The Shampoo

The Shampoo by Shirley Jane is a haircare product. Build-up is the usual reason a product that worked for months appears to stop working. Work it through damp mid-lengths and ends, keeping oils and masks off the roots unless the label says otherwise. Discounted listings come and go, and rarely at the same shop twice. Store it away from steam and direct sun; both shorten the life of the formula. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
