Tapered triple side cuts on the spoolie give versatility and control in application. The points of the triangle help you move and shape your brow, and the flat side grooms and fluffs.

Fluffy brows
Absolutely love this product. I use it sparingly and it gives me beautiful fluffy brows. I now wouldn’t live without this product, it’s made such a difference to my brows and overall look!

Easy to use and natural finish. Would be better with a smaller application brush

It’s okay, but you need a light hand
This brow gel is okay, but I find it’s really easy to apply too much product/colour. Despite that it sets well and I would consider trying the clear one at some point in the future.

Great for darkening the fairest hairs!
Really like this for catching the fairer hairs in my brows and making them look more uniform and less patchy!

Best eyebrow gel
Really amazing! I have tried several brow gels and this gives the most full and natural looking result. The shape and size of the brush is perfect, I don't get any on my skin. I find the fibres in it make my brows look bigger and thicker. I bought this for my mum who has grey hair as I was worried the taupe would be a bit warm. I tried it too and it is a perfect ash brown, a bit darker than what I expected. I did not find any flakes at the end of the day, it held the shape very well and was easy to remove with my micellar water. I am going to buy the taupe for myself to try something a bit lighter in colour, but I definitely would recommend this product, and this specific colour for grey/ash coloured hair. Very impressed.
