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.

I really like this probiotic formula. It's easy to use, has no fumes, and really has made a difference in the look of my bare nails- they look and feel healthier after just a week.
This unique product is awesome

I've been using this probiotic for past 2 +years and really love how it conditions my bare nails. I remove any polish on my nails and use this between salon manicures. It gives my nails a chance to breathe and recover from polish. Prior to applying the Probiotic Instant Boost, I apply the Fresh Glow Cuticle Remover followed by Nourishing Cuticle Oil. Taking time to gently use my fingers to work each product in. Then I apply the probiotic and after a few minutes I use my fingers to rub t it in. Photo below shows finished product. I have purchased the probiotic for a friend and she loves it. I am 70 years young and a long time fan of Londontown products and recommend each and every product.

I use in conjunction with Mani Bright Nail Scrub and Soft Touch Nail Scrub. Nails began to yellow from working with certain materials, so used Mani Bright Nail Scrub (gently), then Soft Touch Nail Scrub and applied the Nail Probiotic for 10 minutes. Finishing touch with Sheer Strength Nail Blush - Concord. Voila! Healthy looking nails again!
