Great shampoo

Love this shampoo. Just makes my hair thicker and more manageable. Bought one bottle and after a few uses I had to buy more in your Labor Day promotion.

Works well

I am always a little skeptical of hair products that claim to thicken hair, but after trying this, can say it actually does make a difference. It also smells good!

Hair feels good again

The shampoo demonstrates high quality, effectively cleansing and adding volume to my hair. I would appreciate a larger product volume per bottle.

Excellent Product

Particle shampoo provides a decent amount of lather with just a small amount of this product. This means a great feeling at a very low cost. I would suggest using Partical Shampoo to anyone who wants a clean product at a reasonable price.

Using particle

I bought Particle hoping it would make a difference in my thin, and continued thinning hair. I am a woman but figured hair is hair!! Too early to know if it will promote hair growth but i am very happy with the way it helps my hair look healthy and fluffy!! And enhances the slight natural curl. I will continue to use this product!!!

My soon to be husband has mentioned thinning hair. I absolutely do not care! He is perfect in every way. He is the lover of my soul

I don’t know if I am growing any more hair but it is the nicest shampoo I have ever.
