4% Niacinamide Oily Scalp Serum

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.

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.

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.
