Spring’s almost here — time for some fun in the sun! But we all know that increased heat in tempertaure 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) is the affordable anti-frizz product that has nearly 3,900 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.​”
