Amazing
I had already been blown away by other products from LondonTown. Polishes, removers, base and top coats had all gotten my nails stronger, almost unbreakable. Then I saw the Probiotic Boost and we had definitely hit on the last bit for perfection. I haven't worn natural nails for forty years; most of...

Nail Probiotic ?
The instructions are too vague. Sometimes you put it on then wash it off, other times leave it on. There is no direction on how often it should be used. And my nails looked nothing the the nails in your video after applying this. I don't know if it's working because I don't know if I'm using it cor...

Great for hydrating nail bed
I like this mask for the nails however I do not wash it off. Ive been apply every day for about a week. My nails are less dry. I will continue to use. I took off one star because of the nail brush was stiff. I replaced the nail brush myself.
Purely Magical!

I have very dry brittle and/or peeling nails. I started using the whole Londontown line with the intro kit and bought the Probiotic with my second order in July. Not only do I love this product, I believe it's been the most beneficial to my nails. Using the cuticle oil daily, this before a weekly manicure with the Nail Veils I haven't had nail this nice in 15+ years. I love this entire nail care line and totally recommend this product 100%
Really helping my nails

I have issues with autoimmune disease that impact my nails, making them thin, brittle, rippled. They peel off very easily. I have started taking two polish free days between each manicure and applying this product three times daily. I do not wash off the product, but leave it on until it's dry. Please note that this is significantly different than the product directions on the labeling. After two cycles of this treatment cycle, my nails are much improved. The only thing I'm doing different is using this London Town Kur nail probiotic instant boost, so I'm going to give this product the credit. Please note that this picture shows the product while still drying, there is no other product applied for shine.
