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.


RRP £24.99

London Brow Lamination Kits made in England vegan and cruelty free with waterproof brows

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!

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.

    Good product

    Softens the brows agains temporarily which helps with brittle over processed brow hair. Not sure if it’s reversing any damage but overall a good product to have.

    Absolutely love this brow serum and so do my clients, it's the perfect consistency and lasts ages. Much better than castor oil which can be too thick.

    I’ve loved retailing this to my clients for brow lamination and lash lift. They’re coming back for their next treatment with the hairs in great condition and giving me really good feedback! I kept one for myself and loved it on both my lashes and brows, could really notice the difference after using it for a couple of weeks!
