Instant Results!

Review by Jada, 19

I have always been interested in eyebrows and it has been a dream of mine to achieve thick arched brows. I discovered Rapidbrow several years ago and I swear by it!! In as little as 2 weeks I saw instant results. Thank you for creating such an amazing product and it is definitely worth every penny. Rapidbrow will always be my favourite product in my beauty bag!!

Review by Catherine, 41

I just wanted to email you to tell and show you my brow journey.
I'm very fair haired and I over plucked my brows in the 90's. My brows never really grew back just fluffy white blonde hairs. This has made me quite miserable, especially with the growing brow trend.

Anyway as a last resort I tried RapidBrow. To be honest I wasn't expecting very much. I diligently applied the serum twice a day, after about 2 weeks I thought I started to notice some extra fluff (but I wasn't sure) after a further week I was convinced I saw more hair.
After seeing this I decided to book in at my amazing local beauty salon (Savage Beauty in Devizes Wiltshire) to have the the HD Brows treatment. My beautician Emma was amazed at how much new fluff was there!! I have now been using the serum and having my brows waxed and tinted for 5 months and the difference is staggering!!

Review by AVRIL

Just want to say I started using RapidBrow on 9th April and have seen a fantastic improvement. Didn't believe it would work but it really does. I have eyebrows and don't even need to colour them any longer, great product. (Posted on 31/08/2016)
Safe to say, this stuff definitely works

Review by EmmieGee Blog

‘I have wanted to change my short, paltry eyebrows for a while, I longed for the power brow of the Cara Delevingne era but had no idea how to achieve it. So when I got the chance to try RapidLash's RapidBrow eyebrow enhancing serum I was overjoyed. I guess I will just let the pictures do the talking and we will see about that Cara Delevingne claim eh?’ (Posted on 31/08/2016)
