To help you through the last and hottest weeks of summer we asked our staff for their product must-haves and tips on how to use them. EDRIS: August the hottest and most humid month in NYC but don’t fear we have the product that fights humidity and prevents frizz-prone hair. Oribe’s IMPERMEABLE is a must-have product and it absolutely WORKS!!! No matter your hair texture; straight, wavy, curly or kinky, Impermeable will keep frizz at bay! A great way to use impermeable spray (and to ensure a fortress around your just blown out hair) is to spray each section lightly before using your flat iron. This will lock in the product for an extra layer of protection and battle frizz even in the most humid dog days of summer. There’s nothing like having certainty and confidence in your tresses. It’s a great alternative to hairspray and I use it through out the summer as my go-to finishing product. ALEXIS: I, for one am not a person who likes the feeling of product build-up on my hair. The less product, the better. When using products on others, I also like to go by the same motto. One of my favorite products to use is the Shu Uemura, Satin Design. Satin Design quenches the hair thirst, provides sun protection, provides heat protection, and doesn’t leave a film. This product can also be used on damp or dry hair. When used on damp hair, I like to cocktail it with Shu Uemura Essence Absolue Oil if the hair needs extra moisture. When using the two products, I like to use a ratio of 2:1. I commonly pump more of the Satin Design than the Essence Absolue oil when combining the two. The foundation of the Satin Design gives the hair a nice soft touch…
