Summer’s finally here — time for fun in the sun! But we all know that heat and humidity can mean not-so-good hair days ahead. Perhaps Amazon’s best-selling hair serum​ ​​is the solution ​we've needed all along.

Herstyler Hair Repair Serum ($12) sales have surged by over 12,000 percent, according to Amazon’s “Movers and Shakers” list — and the affordable anti-frizz product has over 2,400 rave reviews​ to back it up. The shine serum is made with aloe vera, and argan oil condition strands to improve luster and nourish strands while taming frizz.

​Fans of the serum call it a "game changer" and the "best hair product ever." One 5-star reviewer explains, "This is probably the best hair product I've ever used! I have baby-fine, wavy hair that's prone to frizz at the slightest hint of humidity in the air. Most products are too heavy for my hair, making it limp and greasy."

​Another notes, "My hair was always wavy, but now in my 50​s,​ my hair is very curly.​ ... ​​Without a doubt the best serum I have used (along with one other product for curly hair). My curls are soft, no frizz and I don't have to use three, or four products, which would leave my hair curly but not soft looking​​."​

"I couldn't be more happy with this product. I gave it five stars because it's perfect. Smells perfect. Price was perfect. And it works perfect​," raves one happy customer. "I have frizzy,​ ​thick​ ​and corse hair. Sometimes a girl needs a little help to have a good hair day, and this is my help in a bottle or should I say miracle in a bottle. Really does help with frizz and shine.​"​
