I just got the OUAI Hair Thickening Spray and even after only a few uses, I can already see a difference. My hair looks fuller and has more volume without feeling stiff or sticky. It gives a nice lift at the roots and helps my style hold throughout the day. An added bonus, it smells absolutely amazing, like a high-end salon product. I’m excited to keep using it and see even more results over time. So far, I’m really impressed!
