"I am a lady going through the menopause and my eyebrows have mostly disappeared. Saw the good reviews on this product so thought I would give it a try and lo and behold it works! My eyebrows are growing back and I am so pleased." - W. Lass

You must, must use this daily for a month to notice results. I used it every single night after a shower and I noticed the results in a month. After using it for 2 months, others noticed the difference without me hinting at anything. I've used it for over 3 months and I love seeing the length of my lashes and more hair for my brows too. I don't use makeup, so this makes me very happy with my natural look!

Very good serum

I love this product! It saved my brows after years of over tweezing and saved my lashes after a huge fall out with fake lashes.

What The Brow! Eyebrow & Lash Growth Serum
Store owner replied: This makes us SO happy! Have you tried our color capsules? I think with your newly full brows it will look amazing!
I’ve been using the serum on my brows for about a month now. I went to get a brow lamination and my brow tech I’ve had for years commented on how long and full my brows were. Pleasantly surprised with how well this product works!

I’ve been looking for a new brow serum to help thicken my brows, and I’ve definitely found one of the best! I have been using this product for a little over 3 months now, and have seen a difference in my natural brow thickness. Along with their henna powder capsules and styling wax, I get the perfect brow every time, with almost hardly any down time!

I love this lash and brow serum because it’s easy to use and the results are not straight away but you do see the brows getting thicker over time I don’t really use this on my eye lashes but I would defo recommend this product

Love the wand on this product!

Ladies, this is the real deal! I did electrolysis on my eyebrows in high school and since then they have been so thin and had so many bald spots. I am on my second bottle now and man oh man my brows are changing before my very eyes!! I don’t even have to fill them in now when I’m running a more natural makeup look, what a dream!! Ladies, be patient. You must consistently apply the serum every day (ideally right after you come home from work, not right before bed where it’ll rub off on your pillow) and just watch!!

Great product! My eyebrows have been thin and patchy since the 90s, but I’ve resisted expensive permanent treatments and filled them in with powder instead. I decided to let them grow out (only tweezed the monobrow)! I’ve been applying a bit of this serum after cleansing, every night for a couple of months. Hairs have grown in places that they haven’t for years! I’m impressed and will continue using this product. Tip: store upright and a little goes a long way.

So far so good I've only been using this product for a couple weeks, so I haven't seen a huge difference, but I'm hopeful and will be buying more. I'll review again after another month or so!

Great product and costumer care Been using the product for not so much time but already seeing improvements! At first I soaked my eyebrows on it and soon realized i only needed a tiny bit to make it dry overnight smoothly! The costumer care seemed great and was a really nice experience overall :)

The only one that works for me! I have tried several eyebrow conditioners and growth serums and this is legitimately the only one that has ever worked for me! I do have to say that I am super inconsistent with using it (I'm terrible at forming habits and remembering to put it on nightly) BUT, I went from having extremely thin 90's brows to having a defined shape on both of them, one of them almost completely filled in and one of them working its way there. Absolutely recommend!

Confidence Boost I’ve checked out the ingredients on plenty of other serums and I wasn't too happy with all the crazy chemicals. This serum is jam packed with natural oils, has a nice consistency and no irritating smell. I fell in love with this growth serum very quickly. Brows have more volume which is a huge boost of confidence since I used to fill them out with a pencil everyday.
Sam 5/5
It’s too soon to tell, but I do see a little progress. This stuff doesn’t burn my eyes like other products, unless I really rub my eyes too much. I love the purity of the ingredients. I’m all about safe and effective products and I do believe this is one of them. I can’t wait to see what it does!
Riley R. 4/5 Verified
I haven't tried it for 4 to 6 weeks yet to see any progress in my brow growth. Will put a new review once 6 weeks is up. But i do like the oil, easy to use and non irritating. Cute container too.

Time will tell From overplucking for more than 40 years which left my brows with some scaring of patches that the hair had stopped growing its been 2 weeks since applying the serum every night & iv noticed the patch is closing in that the hair around it is growing over it and on my other brow there's 1new hair so it is still early days for full results however I'm staying positive and excited..

Loved it especially for my eyelashes I am so impressed by this serum. I know it is meant for brows but I wanted to give it a try and see what it on my eyelashes. I gotta say it: after a couple of weeks using the serum I've seen my lashes grow longer and I love it. the only downside is that for some reason my bottle tends to leak a little bit
Flavia 4/5 Verified
I like the application wand
Mikaela L. 4/5 Verified
Best serum so far! I have tried at least 4 other brown serums, more & less expensive, and I am staying with this one without a doubt!!!

I really love the product, my eyebrows are growing out nicely. I don't like the bottle tho. I used 2 and they're both leaking towards the end.
