Boosta spray can use alone or with Elevate mousse
"I bought the travel size to try it out and glad I did. If you use enough it can work pretty well by itself, but you can also use less and also use the Elevate mousse and get even better volume. It all depends on your hair type. Mine is fine, thinning (a lot), wavy/curly, but needs volume and hold. You can try both and see what works best for your hair."
