I absolutely love this product, as a lash artist also I have given this to my lash clients while they are resting they lashes, I have seen amazing strong lashes as a result
All I get is positive feedback's from clients. I have had so many of my clients buy 2 or 3 even purchase it for friends and family for gifting.
My clients love so much this serum
Perfect for Brow Lamination aftercare for clients to use at home. I also use it myself & it leaves my Brow hairs soft & silky
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!
Lovely product my clients love it for their aftercare!
I love this product not only for myself but for all my clients receiving lash lifts and brow laminations. It grows brows and lashes, smooths brows and even acts as a lash primer! Couldnt be more satisfied!
The Keratin Boost Brow Serum is an amazing product and the perfect aftercare pairing to go along with your great brow lamination products!
our clients love these after care brow product and they kept at it for maintenance all the time
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!
I love using this instead of a runny oil to look after my brows, it’s so quick and easy and my clients think so too!
Recommend this product to clients
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.
Love this product! I recommend to all my clients for the aftercare once they have laminated their brows
