I’m a Celeb Hairstylist and This Is What I Buy at Costco

Dyson Supersonic Hair Dryer ($400)

Sheila Guillermo, stylist at NYC THE TEAM hair salon founded by Michelle Hong, works closely with celebrities, modeling agencies and major social, fashion and beauty influencers. She also describes the always-popular Dyson blowdryers as the best. “They’re lightweight, quiet and powerful,” she says of the tech wonder. “They dry hair faster and shinier.”

Living Proof Dry Shampoo ($33)

One of her ultimate Costco hair products, Guillermo says this iconic dry shampoo will help make your hair appear fresh and smell clean. “It will help absorb oil while giving you a voluminous feel.” Costco customers call it “light and airy,” and one happy consumer says: “This dry shampoo goes on lightly without a lot of white powder residue, and it does make my hair look like I just washed and dried it. I wash my hair every other day, so it works perfect for me. Give it a try!” Marie Nino, a New York-based hairstylist and colorist, likes it because it actually cleans your hair, removing oil, sweat, and odor while leaving your hair fresh and voluminous. “It’s perfect for extending the time between washes without any residue or buildup, Nino says.

Living Proof Dry Shampoo ($30)

“This is a great choice for color-treated hair, offering nourishment with amino acids, vitamin E, and jojoba oil,” Nino says. “It’s free from parabens and sulfates, dermatologically tested, and pH balanced, making it a gentle yet effective option to maintain vibrant color and healthy hair.”

Mason Pearson Pocket Bristle & Nylon Brush ($82)

Nino calls this brush a “must-have” because it combines natural boar bristles and nylon for optimal hair care, promoting shine and reducing breakage. “Handmade in England, this brush offers superior quality and craftsmanship, making it a luxurious addition to your hair-care routine,” says the pro.

Olaplex No.3 Hair Perfector ($46)

Olaplex is a must-have among many hairstylists, and Costco carries several items from the brand. “This pre-shampoo treatment will help repair and strengthen your hair,” says Guillermo. “It’s meant for all hair types, but especially beneficial for people who color their hair.”

Kerastase Bain Satin 2 Shampoo ($39)

Costco customers call Kerastase “simply the best” and Guillermo agrees: “Kerastase is so great! It’s a quality shampoo for normal and colored hair,” she says. “Plus, it’s usually really concentrated, so it can last you so much longer.”

GHD Platinum+ Styler 1″ Flat Iron ($170)

Fast, lightweight and sleek, Guillermo says the GHD straightener “is one of the best of its kind. It will help you achieve straight hair or waves and will last you a lifetime!”

Nino is also on the GHD train and says the tool is one of her top choices. “The GHD Platinum+ Styler, available at Costco, is a must-have because its revolutionary tri-zone technology provides heat that’s safe for your hair, making it stronger and shinier. It evenly distributes heat to reduce breakage by up to 50 percent and increase shine by 20 percent. The wishbone hinge offers better control, and the high-gloss floating plates ensure a smooth, sleek finish. With universal voltage and automatic shut-off, it’s a top choice for celebrity hairstylists and anyone looking for professional, worry-free styling.”
