GrowPotion Tonight, Brow Team Tomorrow

When we launched Air Brow - Clear, our community was so impressed by the improved appearance of their natural brows, they started to apply it to their brows and lashes overnight.

 Sheena wanted to create a product formulated specifically to wear overnight (without the definition and hold of the brow gel), so we added 6x more powerful and effective hair-boosting actives in a concentrated serum to create GrowPotion.

 Now introducing the nighttime treatment partner to your daytime brow + lash routine.

    Works great

    My wife and I have been using this for a month and have both seen tremendous growth and thickening of our eyebrows.

    I wish they made one for my receding hairline lol

    It actually... works!

    I didn't expect much from it and I'm so surprised by its efficacy! It's been 3 weeks and my eyebrows are growing so much more, it's been years I haven't seen that. Thanks Kosas!

    So far so good

    I have very brittle lashes from picking them years ago. I also have straight Asian lashes, but after a month of regular use, I can see them getting longer. I can also see more growth on my broken lashes. My eyebrows also seem fuller, especially in the middle which was what I was looking for.

    Never have I ever had fluffier lashes

    I was super skeptical when I started using this because it doesn't have any hormones in it, but my lashes have grown like CRAZY. It's the first one I've been able to use consistently because it doesn't irritate my eyes. LOOOOVE

    Brows Do Grow Back

    I was skeptical about this product. After using each night for just a couple of weeks I can actually see new growth and my wild looking brows are now tame and in place.
