I’ve used this primer for several months now and notice a significant reduction in frizz, especially after blow drying. The hair feels softer and more manageable. It’s a must-have in my styling routine.

The shine it adds is subtle but noticeable. I use it before flat ironing and feel my hair is better protected from heat damage. It doesn’t leave a greasy feel.

After switching from a regular leave-in, I see less flyaways and my hair looks healthier. The 6-Oil Blend seems to deeply hydrate without weighing hair down.
