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! 😍

Grow is my favorite product - it has helped so much, so I don't shed as much anymore and my hair is stronger again 🤩🍀

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 🥳

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.
