Ingredients
GROW has truly worked wonders on my now-thinning hair. There wasn't much hair left after two pregnancies over the past four years. After just three months of using the product, I can already see new fine hairs peeking through! 😍
Emma Birkedahl
I love GROW! It's made my hair healthy and voluminous again after several years 😍 I get so much attention for it!
Sophie Bengtsson
Grow is my favorite product - it has helped so much, so I don't shed as much anymore and my hair is stronger again 🤩🍀
Signe Ulderup
As a man in my prime, I'm absolutely in love with GROW. I use it morning and evening, and it saves my hair — maybe it can also help me avoid losing more hair? 🙌
Mikkel Jensen
Grow is something truly unique and the results are SO noticeable 🥰 After my second maternity leave, I felt my temples were getting a bit too visible 😜 but after using Grow, they've completely come back 🥳

A great match for GROW
Cana Cares shampoo soothes a stressed scalp and delivers deep moisture, while the conditioner strengthens fine hair strands against breakage — without weighing hair down or making it greasy.
Use the product correctly
Luckily, it takes no more than a minute — or maybe two on the days you take your time.
Use it morning and evening
Apply 2 pipettefuls (Note: the pipette is intentionally not filled completely) morning and evening for at least 90 days to experience the full effect.
Massage Grow thoroughly into the scalp
After applying 2 pipettes of Grow, be sure to massage it well into the scalp — that’s where all the magic happens.
It only takes 2 minutes of your day
GROW doesn't require daily hair washing, as it doesn't make your hair greasy. So it takes at most 2 minutes of your day.
Continue the routine
When you have tried Grow morning and evening for 90 days and are satisfied with the results, we recommend continuing this good routine to maintain a healthy balance in the scalp and help prevent further hair loss.

Customer Reviews
Extremely satisfied with everything I've bought ❤️
The products work and are so lovely
⭐️⭐️⭐️⭐️⭐️
It works!!
I've been using Grow for 7 months now. My hair has become fuller, and my receding temples are now filled with hair. So I'm very satisfied with the product.
Amazing
I never expected such a noticeable improvement in my hair. Like all Canacare products, it simply works.❤️
Grow
Easy to use, but I can't tell the effect after only 14 days. You state that it can take up to 3 months to see a visible effect.
Grow is effective
I've been using Grow for about 6 weeks. I'm still experiencing quite a bit of shedding, but I can feel a difference in my hair since I started using Grow morning and evening. I hope the positive effect continues so I can get my formerly so-thick hair back.
Good product
I've used it for half a year and think it helps.
It works
When you get the product there's no information on how to use it. But you're asked to review it on trustpilot before you've even used it. Apart from this silly issue, it works on my hair, which is affected by hereditary hair loss. It's easy to use and doesn't make my hair greasy.😊
Helps with hair
-
I somehow need a bit more time to try your product than just one week. I don't really know what to make of it yet. But it's a nice bottle and everything is fine. I apply it twice a day.
Order handling
I bought GROW but haven't started the intervention yet. I'm looking forward to it and excited. I do want to praise Cana Care for how they handled the purchase. Shortly after buying I received an informative email about how to use the product optimally. Now that's service! I even replied, assuming it was one of those noreply emails, but I received the loveliest response! Cana Care simply feels so professional and reliable to me. I'm actually a bit sad I haven't shopped here before — what have I missed?! But I've decided to instead look forward to future great Cana Care experiences ❤️
New Hair
I've just started my 4th bottle of GROW. I can see new hairs peeking through, but I still feel like I'm shedding quite a lot.
It actually works, I have new hair on the way.
I’m really glad I chose to try Grow. I thought my hair had become very thin, but when my husband said, “you’re getting very thin on top,” it dawned on me that maybe something could be done. I saw an ad on Facebook for Grow and there was a good offer on the product, so I thought, why not try it — it would probably also be good for my scalp, which was a bit irritated. But now I can see that my hair on the scalp isn’t as thin and the scalp isn’t as red as it was before. I’m so happy I pulled myself together and tried it. I now buy it when it’s on sale so I have enough for a while and it doesn’t become so expensive in the long run.
Grow
Delivers on its promises — my hair has become thicker
Works
I was a bit skeptical, but I have to say it really works.
Noticeable effect from GROW
I was a bit skeptical, but after about 2 months both my hairdresser and I could see a clear difference. My hair loss has stopped, and there are many new hairs at my hairline and across my scalp.
It works
But… you have to do as Cana says, twice a day. I used it for 8–10 months with no effect because I only used it occasionally.
Fast, precise delivery of a top product 🤗🤗🤗
Fast, precise delivery of product GROW — top-notch 🤗🤗🤗
I can really feel a difference in my hair
It started when I noticed I was shedding more than usual, and I quickly saw an improvement.
Fantastic products 🙌
Works
Sheds far less and new hair grows
Grow
I've been using grow for a little over a month and no longer have a dry scalp where the skin felt too tight. I shed less than before; what comes out in the shower is more normal now, and I no longer have hair all over the house.
I think it's really good 🤩👌
Helps with dry and irritated scalp.
Thank you for making the best scalp serum. My scalp isn't irritated or itchy when I use Grow every day.
Doesn't shed as much anymore. That's great — I'm eagerly awaiting the next steps.
4 stars so far
I've been using GROW for 2 months and have noticed a healthier scalp, fuller hair, and even some new growth. I'll continue using it and hope for more growth.
Psoriasis
I've got my scalp under control; I haven't had severe flare-ups since I started using GROW, and I no longer have bald patches.
Excellent product
It really works
I am very satisfied, good results.
Products that work. Endorsed by experts
Wow, just wow
I've never had much hair at my temples, and after coloring my hair it caused the rest of my hair to break, so I gave up. But then I was introduced to Grow. At first I was a little skeptical, but now I'm really starting to see results, and it only motivates me to keep going.

Others often ask about
How long before I see results?
We recommend using 2 pipettes of Grow morning and evening for at least 90 days to achieve the best results. After that, you can reduce to once a day if you are satisfied with the initial results. However, we recommend continuing to use Grow daily to give your hair the best conditions, just as you use a facial cream every day.
Can I use Grow while I'm pregnant?
Yes, you may use Grow while pregnant. Our Grow hair serum is free from hormone-disrupting substances, is fragrance-free and has kolbe-A from Kemiluppen, so it can safely be used at all stages of life. It can actually be a very good idea to start using Grow while you are pregnant to help prevent possible hormonal hair loss during the postpartum period.
Will GROW make my hair greasy?
No, Grow doesn't make your hair greasy. One of Grow's best benefits is that it doesn't leave your hair oily, so you can use Grow every day, whether you wash your hair daily or not.
Can men use GROW?
Yes, our GROW hair serum can also be used by men. GROW is not developed for a specific gender and can therefore be used by anyone experiencing hair loss and/or a scalp imbalance. In addition to helping reduce hair loss, GROW also supports natural, healthy hair growth.
Can I use GROW with my styling products?
Yes, Grow can easily be used alongside your other styling products. We recommend applying Grow directly to the scalp as the first step, so the serum has the best chance to penetrate and work optimally. After that, you can style your hair exactly as you normally would.
Should Grow be washed out of the hair?
No, Grow should not be rinsed out of your hair. You should apply Grow after washing your hair (and not before), but of course you can shower and wash your hair as normal.
Can I use Grow on both dry and wet hair?
Yes, you can use Grow on both dry and wet hair. Grow doesn't make hair greasy and doesn't require daily hair washing.
How do I use the satisfaction guarantee on GROW?
If you have purchased GROW, you also have an extended 100-day satisfaction guarantee. Because the product must be used for 90 days before we can guarantee its effect, the satisfaction guarantee on GROW applies for 100 days.
We have just two requirements for you:
To make use of the satisfaction guarantee you must document the results and use the product regularly.
Take photos of the area you wish to treat before you start using GROW, and then again after 1, 2 and 3 months. Make sure the photos are taken from the same angle and in the same lighting so that progress or lack thereof is clearly visible.
The product must be used every morning and evening for at least 90 days for us to guarantee results. If you do not notice a difference, you can email us at info@canacare.com with your photos and your order number. The photos must be dated, for example via a screenshot from your phone showing the date.
