I’ve added the Sick Science PowerCycle Scalp Treatment to my routine — it’s a liquid serum made to support hair growth, thickness, and overall hair structure. It uses NX35™ biomimetic technology to help signal cells naturally and maintain keratin levels for stronger, more resilient hair. I just started using it, so no results yet, but I love how lightweight and science-driven the formula is. sikscience sicksciencepowercycle hairserum scalpserum LTKOver40 LTKselfcare LTKBeauty
