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.

    GREAT!

    I’ve been using this since August and it’s made a difference! I personally noticed a difference within a WEEK but everyone’s different. Here I am in November and still loving this product. My lashes were long-ish to begin with, but now they are curly and others have noticed it too! You can tell by the darkness of my lash line. I’ve recommended this to so many others, but remember PATIENCE and CONSISTENCY IS KEY.

    Clumps and made me lose lashes

    This stuff should be outlawed. I used it and overnight it got all clumpy and I had to pull at it to get the gunk out and LOST EYELASHES. I can’t believe they sell this product, the WORST.

    significant volume improvement

    my eyelashes have always been really thin and sparseish and my brows have been overplucked in the past with some patches that have grown in but are thin. i have been using this for about a month now and i love it. my eyelashes are significantly longer (pretty shocked by that tbh) and my brow patches are showing realistic growth. wish i took before and afters but oh well. worked for me! would recommend absolutely.

    Didn't like product, but loved the customer service

    I did not care for this product, it's thick and once it dries it was stuck in my lashes and very flaky. I reached out to Kosas and they refunded me and I didn't have to take the product and ship it back which was really nice. Didn't like the product but liked the customer service!

    I feel like it work well but leaves a glue-like film

    It seems to be really helping my brow and lash growth but I will say it dries to a film like when you were a kid and got glue on your fingers and had to peel it off. I only use one dip for both brows and lashes. Not a big deal mostly but a few times when I removed it, it took an eyebrow hair with it! Sad when you're trying to increase the fullness of your brows.
