"I have used this volumizer ($35; sephora.com) on every single one of my clients," says hairstylist Marcus Francis, who works with Liv Tyler. "It works on all hair types, and is guaranteed way of adding instant volume and texture."

"If this leave-in conditioner ($10; drugstore.com) ever gets discontinued, I'll have to quit doing hair!" says hairstylist Kristin Ess, who uses the product on Lauren Conrad. "The product completely changes hair in just a few pumps by creating perfect, weightless shine and restores the pH balance. Plus, it just smells epic."

"I have always loved this camellia oil ($20; tsubaki-abura.com), and it's perfect for making hair extra shiny," says hairstylist Jenny Cho, who creates Jessica Chastain's glossy strands with the product.
