Keratin Boost Serum

​​Look after your laminated brows with our nourishing, keratin-based brow boosting serum. Not only will our brow serum infuse essential oils and nutrients back into your brow hair, it will keep your brows strong with necessary keratin proteins and plants extracts. 

We designed our amazing Brow Boost for you to apply within four hours of your brow lamination or use it as an overnight intense oil. You can also apply it when you brush your brows up whilst doing your makeup to give them a glossy finish while keeping them strong and healthy!

Brush gently onto brows daily or twice weekly as required.

*Also works as a great lash serum.

Some Extra Love for Your Brows

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.

    My clients absolutely love the London Brow Keratin Lash & Brow Boost. Every single client who gets a brow lamination or lash lift purchases one of these to nourish and style their new look. A MUST-HAVE to retail to your brow and lash clients! I use it myself, too!

    My clients are loving these since I started stocking them to retail. It’s nice to know they’re using a good quality aftercare product at home in between appointments too.
