My Scalp Loves This!
[This review was collected as part of a promotion.] I’ve been using this serum for about 6 months now and I’ve really enjoyed it! My favorite thing about it is honestly the smell. It smells SO good and makes using it feel like such a luxurious part of my hair routine. I also love how fresh and clean it makes my scalp feel without feeling heavy or gross afterward. After using it consistently for this long, it’s definitely become a product I look forward to using and would recommend!

YOLO! You're worth it! It's worth it!
Shortly after I apply RES and gently massage it into my scalp I can feel it replenishing. I wish it came in a larger size.
