I'm looking for recommendations for a frizz control smoothing hair treatment that delivers long-lasting results. My hair becomes dry and frizzy, especially during humid weather, and I'm hoping to find a treatment that leaves it smooth, soft, and easy to manage without causing damage.

If you've had a professional frizz control smoothing treatment, I'd love to know how well it worked and how long the results lasted. Any advice on aftercare, recommended products, or trusted salons would also be greatly appreciated. Thanks in advance for sharing your experience!
