Review: Quality, honest advertising - Excellent product
Review: Pricey but seems to do what it promises - I'm not sure I can afford to keep using this... It lasted me about 3 months, but I only used it 2-3 times a week, not every day. I think it's helping, my hair is growing about ¾ inch per month, which is faster than average, and it feels thicker than before, but it's hard to measure since I have a pixie cut that I'm trying to grow out ASAP. But I'm also using a lot of other products, so I can't say for sure if this one is doing any good, or if it's the others. It's not greasy. It doesn't have a strong odor at all. I'll probably continue to get it as long as I can afford it.

### ⭐⭐⭐⭐⭐ This stuff works. My regrowth is insane.
*by A***S on April 23, 2026*

I can only speak to my personal experience and I have been taking this for two months (since Feb 2026) and am nearing the end of my second bottle. The regrowth has been undeniable. Minimal shedding now and my hair definitely feels thicker. I just purchased my third bottle.
