This is the new scalp serum I just started using — the Sick Science PowerCycle Treatment. It’s a lightweight liquid serum powered by their NX35™ technology to target hair growth, hair structure, thickness, and strength. It uses biomimetic signaling to help support healthier, stronger strands over time. I’m still early in my routine, but I love that it’s designed to work at the molecular level to support keratin bonds and overall hair resilience. sikscience sicksciencepowercycle hairserum scalpserum LTKBeauty LTKOver40 LTKselfcare
