Eva A. ★★★★★

My hair feels so much softer and healthier after just two uses, and I love that I can leave it in without any greasy buildup. The fact that it only needs to be applied once a week makes it super easy to fit into my routine.

Aurora ★★★★★

This leave-in mask doesn't make my hair greasy at all, which is rare for me—I just use it once a week and my curls feel noticeably softer and healthier.

Ava S. ★★★★★

My hair usually feels weighed down by leave-in treatments, but this one absorbs instantly and leaves my waves soft without any greasy residue. I use it twice a week as suggested, and the rosemary scent is subtle enough that I don't mind leaving it in all day.
