Scalp Care Joins the Red Carpet Prep Kit

Hair loss care has moved from a private concern to a front-of-mind beauty category, and the shift is starting to show up wherever a blowout used to be the whole story. Shoppers are reaching past shampoo now, adding scalp serums and LED devices to routines once built around styling alone. Beauty brands have noticed, and they are racing to turn thinning hair into a full product line rather than an afterthought aisle. For a category once ruled by extensions and dry shampoo, that is a genuine widening of the toolkit.
