Penelope ★★★★★

Finally, a serum that actually tackles the root of the oil problem instead of just masking it—my scalp stays fresh for a full extra day between washes now. The pH-balanced formula is a game changer, and I love that it's leave-on so I don't have to rinse.

Evelyn ★★★★★

Third week in and my scalp actually feels balanced, not stripped or tight like with other treatments. The pH-optimized formula clearly does its job since I'm now washing every other day without that oily buildup by noon.

Brian R. ★★★★★

My hair used to get greasy by day two, but this serum actually gets me to day four without that heavy, oily feeling. The pH-balanced formula is the key, I think, and it doesn't weigh my roots down at all. Worth every penny for the extra time between washes.
