"I am a lady going through the menopause and my eyebrows have mostly disappeared. Saw the good reviews on this product so thought I would give it a try and lo and behold it works! My eyebrows are growing back and I am so pleased." - W. Lass

"I used to go to get my brows done at the salon regularly, but after about 6 months I noticed that after each time my brows seemed thinner, and my brow hairs wouldn't grow out to their original length. I became a bit stressed and self-conscious because I normally have quite nice, natural brows, but it's as if the hair didn't grow back properly after each shaping (waxing and tweezing). I used Baebrow's tint before so I decided to try their serum as well. I started using this serum and after about 4 weeks my brow hairs seems to be much longer and I am finally able to grow it out and brush it up to achieve the "feather brow" look, which I like because it works with natural brows. I also have dry skin and I feel like the serum moisturises the skin under the brows so I don't experience any dry skin flaking." -Anna 

"So I find these things really hard to judge online - there are so many options / good reviews and knowing where to start is impossible. a friend recommended this though and I was impressed. Other serums I've used may have worked quicker, but if you look closely at ingredients, they are not actually natural and the ones that don't claim to be have given weird side effects. Would highly recommend this - I can see my brows slowly coming back to their former state." -Rebecca

"What INSTANT TINT color do I choose?" No worries, here is our guide to selecting your shade :) Keep in mind that INSTANT TINT is a gentle formula and the effects are very natural. We recommend choosing the shade based on your natural hair color and tone. Check out the chart below:

BROWN - A neutral tone suitable for light blonde and light brunettes. This our most delicate tint. Not recommended to cover grey or translucent hairs.

DARK BROWN - A colder/neutral toned dark brown suitable for blondes and most light- medium brunettes. If your hair is already dark or medium brown, then getting a darker tone is recommended like the Dark Brown + Black bundle described below. Suitable for all skin types.

BLACK - If you have dark brown or black hair this is a suitable color. A universal favorite that darkens hair to a dark, bold tone. if your hair is light and you're looking for a bold, more dramatic effect, we won't stand in your way ;) Suitable for all skin types.

GRAPHITE - An ashy grey/black color - suitable for cold-toned dark hair, cold-toned blondes and for light-medium skin types. (but not if your brows are translucent*). A universal favorite that darkens hair to a dark colder tone.

*If you have very light blonde or very light brown hair - the two tint combo pack with Dark Brown will give you a more natural result. If your natural brow hair color is very light blonde, white or even translucent (non-pigmented) we do not recommend the graphite on its own, as it can pick up the undertone colors and look unnatural.


Two Tint Bundles allows you to mix the colors to achieve the tone that suits you best with warmth and intensity of color. Save $5 with these options!

DARK BROWN + BLACK - Most popular option. Ability to control the intensity of a darker brown tone. The Dark Brown on its own may be too light for some, so adding black will let you darken it to your desired intensity. Suitable for all skin types.

DARK BROWN + GRAPHITE - Ability to darken the Dark Brown and achieving a colder tone. Fitting option for cold-toned dark blondes. Suitable for light-medium skin types.
