Reviews

This shampoo really works

"I've been dealing with thinning hair for the past couple of years. Using this shampoo makes my hair look much thicker. It's really helped to bring my self esteem back up. Thank you for the great product."

Laura L. (5/5)

Not impressed

"The shampoo and conditioner are decent much like any others on the market, nothing special. I haven't seen any notable changes. Sadly because it's kind of expensive."

Roechelle S. (2/5)

Great high quality shampoo, smelled & left my hair so much cleaner then others! i would definitely recommend!

"The shampoo smelled so lovely and clean, and i also really loved how well and silky the lather felt. It did great on my hair as far as leaving it looking and feeling clean. I was surprised at the difference it made with my hair being less oily on between washes, which was really nice."

Amber S. (5/5)

Seems to be working

"I'm definitely seeing baby hairs regrowing after a few weeks of use. Would consider purchasing again."

Fresh Clean Healty look!

"Made my hair feel clean. the scent wasn't strong which i like! it was like cool soft minty fresh without the cool feeling. Definitely my hair looke healty and soft, my mom even noticed the difference after one wash which means that it worked! Still too soon to notice a difference on the length."

Jesmarie R. (5/5)

It does work

"Definitely needs to be a pump bottle, not a squeeze bottle. Hair feels a bit dry after shampooing, not soft. And I have very healthy soft natural hair. I probably rip out more hair getting my fingers entangled washing the shampoo out. The conditioner does help. Is it making my hair grow faster? Maybe a little."

Shampoo

"Love how it lathers up easily quite please with the product so far."

Marlyn C. (4/5)

Optimistic Results

"After the first few uses, my hair felt noticeably softer and smoother to the touch. The product absorbed well without leaving any residue or heaviness. I also enjoyed the creamy texture and the light, pleasant scent that lingered subtly without being overpowering. In the short term, I noticed a slight improvement in shine and manageability, along with less frizz. While I haven't seen dramatic changes in length yet, my hair feels healthier overall, and styling it has become easier. Based on these early results, I feel optimistic about continued use. The positive first impressions and short-term improvements make me likely to consider purchasing the product again."

Dirk P. (5/5)

Damaged my hair

"The shampoo and conditioner did damgae.weird to say but the shampoo dried my hair out so bad it felt brittle. I never used a shampoo that made my hair feel like this even. I thought maybe the conditioner will help soften it out but barely. My hair way all I. The shower as it made my hair fall off more than it should. I was so scared and shock ."

Jennifer N. (1/5)

Good scenylt, soft hair

"My hair was very shiny and soft after the first use. The smell was very fresh and my hair felt clean after the first shampoo. The only issue I had later in the day was a having a dry scalp in an area near the back of my head where I am usually sensitive."
