Impressed

Always skeptical with claims but it’s obvious after I shower that the amounts of hair clogging the drain, has since diminished immensely !!! Impressed. Thanks Particle.

Good shampoo

I've tried multiple shampoos over the years, never settling on 'the one'. This may have changed. I like Particle. I can use it daily or miss a day or two. I like the fullness, the way my hair looks and manages after a shampoo. Haven't noticed any hair loss since I've been using it.

Best Shampoo available

The lush lather and noticeable thickness are what make this shampoo #1 on the market today!

Wonderful Shampoo

This shampoo is my favorite. The ingredients are gentle on the hair but still leave it clean and full.
