In terms of efficacy, the Ultimate Blends Hair Honey Repairing Serum certainly delivers on its promises. After incorporating it into my routine, I noticed a significant reduction in frizz and an increase in manageability. My hair felt softer and looked shinier, which is often a challenge for anyone with dry, damaged locks. I found that the serum worked best when applied to damp hair, right after washing. Just a few pumps were sufficient for my shoulder-length hair, and I focused mainly on the mid-lengths to ends. It absorbed quickly, and I appreciated how it didn’t make my hair greasy, even by the next day. For those with particularly dry ends, a touch applied on dry hair later in the day also did wonders without feeling heavy.
