Review: It works - I've been using this serum for almost a year now. This stuff really works, when used daily. I can see the new hairs coming out, shedding is substastially reduced, and my hair does seem to grow faster (not too much, but noticeably). It is expensive, so I always grab it when its on sale. And, if I'm inconsistent or stop using it, I notice my hair starts shedding again. I did try the shampoo/conditioner combo along with the serum but I don't think it made huge difference. So I only use the serum now.
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.

### ⭐⭐⭐⭐⭐ It works
*by H***A on December 6, 2025*

I've been using this serum for almost a year now. This stuff really works, when used daily.

### ⭐⭐⭐⭐⭐ Pricey but seems to do what it promises
*by T***A on January 10, 2026*

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.

### ⭐⭐⭐⭐⭐ Good Hair Growth Serum
*by G***Y on May 15, 2025*

I was very skeptical about this product, but since my hair seemed to be fitting on top, I wanted to give it a try. After about two months of use consistently, I have a ridiculous amount of baby hairs popping up all around my head which tells me it is working! This stuff is expensive, but I think any really good working hair growth serum is going to be expensive and the investment is worth it for me. I’m 35 years old and noticed my hair was starting to become slightly thin on top.
