It really works!

I've seen all the advertisements for growing hair back da,da da.... But I decided to give "Particle" a try. It's been over a month now and I can say it is working. My coworkers even ask me if I'm doing something different with my hair or maybe combing it different. I am truly impressed by the results.

Particle Shampoo

I love this shampoo. It lathers and cleans my hair making my scalp feel great. The scrub brush is a great addition as well!

Shipped on time and arrived as stated.

Haven't been able to try it yet as I just got it a few days ago and am using up the last of my previous product. Hopeful it will be good.

Shampoo Thickening

Like the shampoo, a bit early to know if it’s thickening yet. Hope so !
