I am so impressed with the W3W Hair Growth Serum. After trying several products for thinning hair I was specifically looking for something without minoxidil and this formula has been perfect. The combination of rosemary fermented rice and caffeine feels powerful yet gentle on my scalp. The roll on applicator makes it incredibly easy to apply directly to thinning areas without making a mess and I love that I can control exactly where the product goes. The serum absorbs quickly and does not leave my hair greasy or weighed down which is a huge plus because I can use it even on days when I style my hair. My scalp feels refreshed and lightly stimulated after each use but never irritated. With consistent application I have noticed less shedding and my hair looks fuller especially around my hairline. It feels healthier stronger and more resilient overall. I also appreciate that it works for both women and men so it is something anyone in the household can use. The formula feels clean lightweight and thoughtfully made. If you are looking for a fast absorbing non greasy scalp treatment that supports thicker healthier looking hair without harsh ingredients this is definitely worth trying. Read more

This review is for the W3W Hair Growth Serum with Rosemary, Fermented Rice & Caffeine - Roll-On Scalp Treatment for Thinning Hair, No Minoxidil, Fast-Absorbing, Non-Greasy Formula for Women & Men. I have used various rosemary oils before for thicker hair, but they always feel, well, oily. This serum is surprisingly not oily at all. It is a roll-on and feels light, so it does not leave any type of residue on my hair, which is great. However, the instruction says to use the roller balls to massage your hair/scalp for 5-10 minutes...that is a very long time to spend massaging your scalp, so I have not followed this step. I have not seen any difference in my hair, but I have not been using this for very long. Will update my review if I see any changes after using this for a while. Read more

I've noticed that my hair has been thinning as I get older and this product has helped grow some of my hair back. I've noticed a lot more baby hairs so I know it is working. Read more

This product is easy to apply, has no smell, and isn't greasy. The directions say you don't have to wash it out and I was skeptical but I tried it. I put it on my dry hair at night and let it soak in. By the morning it still looked good enough to apply some dry shampoo and go. I can't speak to whether it helps your hair grow since I have only been using it a week, its worth a try. No negative side effects from using it so far. The directions note that if you stop using it you may not see continued improvement, for whatever that's worth. Read more

The roller doesn't roll very well on your hair so I put it on my fingertips first then apply to my hair where needed. The scent is light and doesn't leave a greasy mess in your hair. Working so far, I can see new growth coming in where I have been applying it! Read more

I really like that this growth serum comes in a roll on form, it is cleaner to apply in that way and also is like getting a head massage. I also like that the serum is not greasy at all. I have not seen any growth yet but I noticed that my hair is not falling as much these days. Read more
