And we thought Kate Middleton couldn't get any more perfect! It's no surprise that the Duchess of Cambridge is known for her amazing hair, but many royal fans probably assume Kate achieves her luscious locks by using super expensive hair products. But, that's totally not the case!

According to People, the 36-year-old's hairstylist Amanda Cook Tucker uses Kiehl's Creme with Silk Groom to keep Kate's shoulder-length hair looking shiny and near-perfect. The best part? The affordable product costs just $16 and can be purchased at Sephora!

Kate's go-to hair serum was revealed earlier this week when Cook Tucker posted a now-deleted photo on Instagram showcasing a plethora of products that the royal regularly uses. The hairdresser shared the snapshot — the caption read, "Think that’s everything! #WorkTrip #Packing" — to show what she was packing for Kate to bring on her royal tour of Sweden and Norway. But, not surprisingly, the photo was swiftly taken down and Cook Tucker subsequently deleted her private Instagram account.

As People previously reported, the pic showed 13 hairbrushes, six combs, three curling irons, and two hairdryers, plus seven hair products placed on a table. In addition to Kiehl's Creme with Silk Groom, Kate apparently uses L'Oréal's Elnett’s Supreme Hold Hairspray ($14.99), Charles Worthington's Volume & Bounce Texturizing Spray ($9.96), and Boots' Essential Hairspray Maximum Hold Unperfumed ($2.84).

The photo also reportedly revealed that Kate's hairstylist uses the Diva Professional Styling Intelligent Heat Argan Tong 45mm to create Prince George and Princess Charlotte's mom's big, bouncy curls. The curling iron retails for around $150. Though the item is currently sold out on Amazon, royal fans can purchase the smaller, 35mm version for approximately $133. Now we can recreate Kate's gorgeous hair easier than ever before!
