Particle Shampoo

Great. Hair feels thick/smoother, and less hair coming out in shower.

SO FAR SO GOOD

After using the product for two weeks I am finding that my hair is smoother, softer, fuller, and more manageable. This was my expectations and I'm not disappointed. I plan on using it for a few months to see if there is more improvement. Looks like this is a long term keeper...

It’s a fantastic product, my hair is healthy

If you use it frequently, and wait a little while for it to take effect while you shower and then rinse your hair, you will see the result.

Noticeably Thicker

I’m new to Particle however upon receiving and using the thickening shampoo I have noticed a huge difference in the thickness of my hair. My one recommendation would be that Particle make a thickening conditioner.
