In my opinion, this dupe for the Keratin Treatment deserves a lot more attention, and it's currently 47% off.

      Quick question: What have you purchased from the Nordstrom Anniversary Sale, and why isn't it a dupe for IGK's keratin treatment? Apologies for the snark, but I truly think everyone should have this product—or rather, this product trio—ready for smooth at-home blowouts. I have used it for years, and it has helped my sleek hairstyles last several days without falling victim to hair-raising humidity. Nordstrom's biggest event of the year is the ideal time to replenish beauty staples (especially luxury items that you genuinely panic about running out of), and you can bet that I’ll be adding an extra IGK product to my stash. I recommend you do the same before the sale ends on August 3 or before it inevitably sells out, just like all the incredibly popular Nordstrom items.

      IGK So Smooth, So Soon Trio

      This set includes everything needed for a smooth, glossy blowout: a multitasking prep spray that provides 450-degree heat protection while detangling, softening, and adding shine; a heat-activated, frizz-controlling blowout balm; and my personal favorite, a heat-protective blowout spray that imitates the results of a keratin treatment. The spray alone gives me the sleek look I desire, but the trio multiplies those results threefold, especially during high humidity. To clarify, I don’t think there’s anything wrong with frizz. Frizz can be attractive, adding texture and life to a look. I usually emphasize the fluff for my wavy-curly hair, but I’d be lying if I said I didn't yearn for a super-smooth blowout occasionally. On those days, I aim for nothing but polished, glass-like lengths, so I reach for my Good Behavior Smoothing Spray.

      This spray is formulated with unique bonding polymers that adhere to hair, offering a protective layer around the hair shaft. This effectively reduces frizz and provides a high-shine finish. These polymers activate with heat, functioning similarly to a keratin treatment. Additionally, it contains spirulina protein to strengthen strands during styling, much like how a professional treatment infuses hair with keratin (the protein that makes up your hair).

      Using the Smoothing Spray is straightforward. Just mist it over damp, freshly washed hair in sections, ensuring every strand is fully coated, then blow-dry your hair as usual to activate the formula's smoothing benefits. For an extra boost of smoothness, you could mist it on dry hair before using a flat iron, but blow-drying alone does the job perfectly for me. Numerous reviewers agree, and one Sephora customer even referred to it as "Instagram hair in a can." They added, "My hair has NEVER looked and felt this amazing from a simple blow-dry, ever. Not greasy or oily, doesn't feel heavy, shines brilliantly, is bouncy, sleek, and has a silky touch." I couldn't have expressed it better!

      The Smoothing Spray does provide its own heat protection, but now that it’s available in an exclusive set, I plan to make use of the Prep Spray for added strand protection. (Remember, dehydrated, heat-damaged hair only leads to more frizz!) I also can’t overlook the Blowout Balm and its keratin-like benefits. Considering how effective the spray is for achieving a sleek, shiny mane, I can only imagine the results I would get by using both products together. The spray is typically priced at $38, so getting three high-performing products for $53? Sounds like an obvious choice.
