“I have had less shedding in the last few months and my scalp feels smoother”

I have tried many different products for hair growth since I was 29, but nothing seemed to work quite well. I just recently discovered this brand through my friends and decided to give it a chance one more time. Somehow, I'm actually seeing great results for the first time. Very happy that I found the products. I've been using the shampoo, the serum, and the red light therapy cap regularly, and I look like a different person.

“Great shampoo but I don't know if my hair growth is because of it or because of the serum”

★★★★★Jun 3, 2026 Barber asked about my shampoo My barber asked me what I have been doing differently, so something's changing.

★★★★★May 11, 2026 Clean without that stripped feeling My old shampoo left my hair feeling like straw. This one rinses out easily and my hair feels softer afterward. That’s the biggest difference I’ve noticed.

★★★★★Apr 3, 2026 Fits into my routine I didn’t want another complicated step. I just replaced my usual shampoo with this. Easy to use and my hair feels clean without feeling coated.

★★★★★Jun 22, 2026 Better after the gym I use styling products most days and work out regularly. This gets everything out without leaving that heavy feeling at the roots.

★★★★★Aug 3, 2026 Good shampoo, still early Only a few weeks in, so I can’t say anything about growth. As a shampoo, though, I like it. My hair feels softer and is easier to style.

★★★★★Jul 3, 2026 The feel sold me Bought it because I was curious about the ingredients. What keeps me using it is how my hair feels after washing. Clean, soft, and not weighed down.

★★★★★Jul 17, 2026 More than I usually spend It costs more than my regular shampoo, so I was hesitant. I’ve enjoyed using it so far, especially how easily it rinses out. I’ll finish the bottle before deciding whether to reorder.

★★★★★Apr 3, 2026 Less of a battle with the comb My hair usually tangles after washing, even though it’s not very long. It feels easier to comb through with this. Small thing, but I notice it every morning.

★★★★★Sep 3, 2026 Actually finished the bottle I tend to buy a shampoo, use half, and move on. Finished this one. Nothing dramatic to report, I just liked how my hair felt using it.

★★★★★Jan 17, 2026 Hairline feels fuller About 3 months. Less hair in the drain and the hairline feels thicker when I run my hand through it.

★★★★★May 3, 2026 Doesn’t flatten my hair My hair is fine, so anything too heavy makes it look flat. This leaves it feeling light after it dries. Still use my usual styling paste afterward.

★★★★★May 17, 2026 Keeping the rest of my routine I haven’t changed my conditioner or styling products, just the shampoo. My hair feels less rough after washing. That’s enough for me to keep using it.

★★★★★Jun 1, 2026 No leftover film Some shampoos leave me rinsing forever because my hair still feels coated. Haven’t had that issue with this one. Straightforward wash and rinse.

★★★★★Jul 1, 2026 My wife keeps borrowing it Bought this for myself, but my wife has started using it too. We have completely different hair, so I wasn’t expecting that. The bottle is going faster now.

★★★★★Jul 17, 2026 Works with my styling routine I use a matte clay that can be annoying to wash out. This gets my hair clean and ready to style again the next morning.

★★★★★Jun 1, 2026 Worth the wait 6 weeks. Shedding down noticeably. Sticking with it.

★★★★★Jun 17, 2026 Simple enough for me Wet hair, shampoo, rinse. That’s about as complicated as I want my routine to get. Been happy with how this fits in.

★★★★★Jun 1, 2026 Still need conditioner I like the shampoo, but my dry ends still need conditioner afterward. The combination works well for me. Wouldn’t expect one product to do everything.

★★★★★Jun 3, 2026 Good after a long day I wear a hat for work and my hair feels pretty greasy by evening. A wash with this leaves it feeling fresh again.

★★★★★Jun 17, 2026 Took it on a trip Put some in a travel bottle because I didn’t want to use the hotel shampoo. Apparently I’ve become particular about shampoo now.
