Superstar ingredients like biotin, rosemary and castor come together wonderfully in our
Boost Hair Serumto provide hydration, volume and a thicker appearance.
Three weeks in and my ponytail actually looks fuller, which I did not expect from a serum. The castor oil makes it a little tacky if I use too much, so I stick to two drops on damp roots.
My hair feels noticeably thicker at the roots after three weeks, and the rosemary scent is subtle enough that I don't mind it lingering. The serum absorbs fast without any greasy residue, which was my biggest worry.
I was skeptical about serums, but this one is genuinely different. The biotin and rosemary combo has my hair feeling noticeably thicker and looking fuller after just a few weeks of consistent use.
