Achieving healthy hair can be tricky, especially if you’re someone who constantly styles it with heat, like I do. That said, I know it takes a lot of products to save strands from a complete disaster. That’s why as I’m searching for new formulas for damaged hair, I’m nabbing the Karseell Collagen Hair Treatment, which is a hit among shoppers.

Karseell Collagen Hair Treatment 

$24 $21 at Amazon

Formulated for all hair types, this conditioning treatment deeply nourishes tresses to repair dryness and damage. And it’s all thanks to its key extracts: argan oil, wheat protein, and collagen, all of which offer a slew of benefits for softer and silkier strands. More specifically, the Karseell hair mask aims to boost moisture, reduce breakage, tame frizz, and add shine. 

While these strengthening ingredients don’t directly impact growth, they can create a healthier hair and scalp environment to promote growth. This leave-in treatment is easy to incorporate into your daily routine if you wash your hair every day, too. Just apply it for 10 minutes post-shampoo before rinsing it off. 

Thousands of reviewers say that the Karseell hair mask improved the overall appearance and texture of their hair. “This deep conditioning mask has transformed my hair, leaving it incredibly soft, smooth, and healthy,” said a shopper who dubbed it a “salon-quality treatment in a jar.” Another user called it a “game-changer” for their “brittle, straw-like hair” that’s now become “fuller and healthier.” Similarly, other customers raved that it leaves hair “smooth like silk in seconds” with “zero brittleness.”
