Keratin Boost Serum

We love lamination, but sometimes your brows will need some extra TLC during lamination treatments. That’s why we’ve developed our keratin boost serum to keep your brows healthy, conditioned and to help preserve your brow lamination. This product can be used within four hours of your lamination session, but if you just want to use the keratin serum for hair growth, apply before bed and leave on overnight for strong, luscious brows that look healthy. If you need a little keratin boost in your life, look no further than London Brow to help you get your best brows yet!

Formulas You Can Trust

We want our customers to feel confident not only about their brows, but about the products they’re buying too. Every brush, eyebrow mask, and keratin serum for hair growth is made with you in mind. We’re committed to excellence, but also to kindness. We’re a vegan and cruelty-free company, and all our products are manufactured in the UK. We offer super fast shipping, and our excellent customer service team is always available to answer any questions you may have. We’re setting the standard when it comes to brows, and we don’t plan on stopping. Every brow lotion, keratin boost serum, and salon essential is thoughtfully developed, so you can bring the best in brows to everyone.
