Yahoo Senior Beauty Editor Jennifer Romolini swears by this frizz-reducing bestseller.

“Every now and then a hot internet-famous product comes along that I don’t think will ever work in a hundred years and I’m pleasantly surprised (okay, more shocked) when it does,” she admits. “That was the case with this strange tube of Elizavecca’s TikTok-famous collagen and protein hair mask.

It’s a restorative treatment meant to transform even the driest, strawiest hair into silky-soft locks. You work it into your hair after shampooing and after 5-15 minutes the before-and-after experience is seriously profound: my thin, dry, long-dyed blonde mane was bouncy, soft and smooth as a satin sheet and, best of all, I didn’t feel burdened. Although it makes your hair a little greasier than normal, the conditioning impact is worth it; my results lasted for weeks.”

While this isn’t the biggest discount, you can’t beat paying just seven dollars for a tube!
