Great first impression!

DominykasSeptember 21, 2025✓ Verified purchase

I’ve only been using the Roll & Grow Hair Growth Serum for about 4 days, but so far I really like it. The roll-on applicator makes it super easy and mess-free, and the serum feels refreshing on my scalp without being greasy or heavy. I also like that it’s made with clean, natural ingredients like rosemary, caffeine, and biotin, it feels gentle but effective. Obviously it’s too early to see big results, but my scalp already feels healthier and more nourished. Excited to keep using it consistently and see how my hair improves over the next few months!

Serum is not oily at all and has flight tingling sensation.

mimersFebruary 10, 2026

I absolutely love this batana and rosemary hair growth serum roll-on. This roller bottle though had bubble wrap, did not have any shrink wrap on the lid which concerns me because the screw cap could have easily unscrewed during shipping. Luckily my bottle came intact and I was able to experience its wonderfulness. I have used many different concoctions of rosemary hair growth oils...and have even made my own. But this serum is unique in that it does not feel oily at all. It has a slight tingling sensation when first applied and it feels wonderful. The scent of rosemary is strong and I love it! It's too soon to tell if it's helping with hair growth but after using this serum for about 2 weeks, I have noticed there's less hair falling out after I shower and brushed my hair. Very good non-greasy serum. I definitely recommend this serum provided the manufacture slap on some shrink wrap, not only to prevent tampering but also to secure the cap during shipping. This product is made in Lithuania. Read more

Really easy to apply

ReaderFebruary 3, 2026

I can’t yet comment on the actual hair growth results of this product as I haven’t been using it for 3-6 months yet, but I will say that so far this product is definitely something I will continue using to see if I get results. I have used other products before in other forms – a liquid that when I put on drips down way too easily and won’t stay in place and a foam product that was slightly better, but still would kind of drip down on areas where I don’t particularly want it. Both these products would take a long time to dry and were honestly just a hassle to use that I just accepted the loss and just stopped using them. When I saw that this product was in a roller ball form I decided ‘well I gave the other two types a shot and didn’t like them, maybe I’ll like this one better’ – and I can honestly say that when it comes to applying this, it’s way easier. I can do it without looking in a mirror or I can have my wife apply it for me when we’re in bed before going to sleep. I just give the bottle a shake and then roll it over the spots where I am hoping to see hair growth. My first time applying it, I thought that it may have run down a little bit, but it’s nothing compared to what other brands do and I think that was because I had the bottle tipped upside down completely and rolled a lot out. If you tip the bottle more to the side or at just a slight angle I had no problem at all with anything running down or too much coming out of the bottle. This stuff, I feel, dries a quicker than others and it doesn’t really leave any residue feeling on my skin – which I like. It also dries clear so if you use this in the morning you don’t have to worry about having dried white liquid marks all over. There is a slight smell with this, but it isn’t anything chemical-smelling. To me it has a minty type of smell to it which smells fresh but it also isn’t too powerful that it makes me not want to use the product. The smell also goes away once it the liquid dries. I will say that I don’t feel that it is a greasy product which makes it easy for me to use too. For now, I’m giving this 5 stars for how easy it is to use and if I see hair growth results, I’ll come back later to with an update on the progress. Read more

Leaked Out Upon Arrival

LindseyFebruary 2, 2026

I got this roll-on hair growth serum to use. When it came in, however, the serum had leaked out of the container. The container was wrapped tightly in bubble wrap, so I'm not sure why the container leaked out before it arrived. Since I wasn't able to use it, I cannot comment entirely on its benefits or what I like/don't like about it. One thing I can comment on is the smell. I really like the smell of the hair growth serum. It's a fresh, clean smell. I wish the serum hadn't leaked out so I could try it out. Read more

Hopeful this works for me!

Becca ZMarch 7, 2026

I’ve recently started using this Roll & Grow Hair Growth Serum and so far it’s been very easy to incorporate into my routine. The roll-on applicator makes it simple to apply directly to the scalp without making a mess, which I really appreciate. The formula includes a nice mix of ingredients like rosemary water, caffeine, biotin, and plant extracts that are known for supporting healthy hair. It also feels lightweight and non-greasy, so my hair doesn’t look oily after using it. Since hair growth takes time, it’s honestly a bit too early for me to say if it’s making a noticeable difference yet. For now, I’m happy using it regularly and will be interested to see how things look after a few months of consistent use. Read more

Fuller Hair

LisaK.February 7, 2026

I've been dealing with thinning hair for sometime and started using various products. This hair growth serum by a respected company caught my eye so I quickly grabbed a bottle. I have so far been quite pleased with the results. The formula is filled with excellent ingredients, many known to help with hair strengthening. The roller ball has made application a breeze. The smell is divine. I apply it along my scalp line every night then take a full minute to massage it in. After a couple minutes there is little to to greasy residue. My hair does feel fuller for sure. Read more
