Redken Acidic Grow Full Instant Densifying Spray ($40)

"I have ultra-fine hair, so when it comes to leave-in treatments, I prefer lightweight sprays. The Redken Acidic Grow Full Instant Densifying Spray checks the box, delivering fullness and heat protection without weighing my ends down. It provides an instant root lift and thickening effect to my style." — Jessica Harrington, Section Lead, Beauty
