Key Ingredients

Nail Reboot Buffer
Nail Reboot File
Cuticle Conditioner Serum
Replaceable Buffer Pads

How to use

Step 1: File
Before using the nail buffer, we recommend using a nail file to shape the tips of your nails. It gives you a more complete look. Best practice for nail file: Start at the outer edge of one nail. Hold the file at a 45-90 degree angle against the nail edge and sweep the file towards the center of the nail. Avoid rubbing the file back and forth to prevent the nail from splitting. Repeat this movement as needed

Step 2: Buff
Use the buffer with clean, dry hands. Hold the block by its sides between your thumb and finger. (Avoid touching the white pads if possible. The oils in your skin can stain them and lessen the life of the pads.) Use slight pressure to slide the surface of the pad along your nail for about 5-10 seconds. Finish each step on all your nails before moving to the next step.

Step 3: Condition
Use the Cuticle Conditioner Serum for 2 consecutive weeks daily then 3 times a week. Dispense a small amount onto the nail bed of each finger. Then massage the serum into each of your cuticle

BUY THIS PRODUCT!!!!

This stuff is amazing! I wish I had taken a before picture of my nails because DAY 1 they are transformed!!! After decades of wearing fake nails to hide my dry, brittle, splitting and peeling nails I decided to go natural. Well it wasn’t working they looked like hell and it’s painful when they tear and split. I’ve tried every oil, cream buffer, hardening polish and nothing worked. I happened to see this on Amazon and bought it. Ya gotta love Amazon cuz you can return stuff if it doesn’t work. Anyway I used it today and my nails drank in this nail/cuticle serum. It’s magic!!! They look so much better that throughout the day I have dabbed a bit more on and again my nails are drinking it in. This has never happened with any other cream. Buy this you will not be disappointed!!! I can’t wait to see how well this will help them grow.

We've made using the Nail Reboot Challenge Kit simple and effective. Here's a step-by-step guide to get you started:

  1. Nail Reboot File: Begin by using the Nail Reboot File to shape your nails according to your desired style. Start at the edge of the nail and file in one direction, avoiding sawing motions that can cause damage.
  2. Nail Reboot Buffer: After shaping your nails, gently buff the surface of your nails using the Nail Reboot Buffer. This helps to remove ridges, smooth the nail plate, and enhance product absorption.
  3. Nail Reboot Oil: Apply a small amount of the Nail Reboot Oil to your nails and cuticles. Massage it in using gentle circular motions. The unique blend of oils deeply nourishes and moisturizes the nails and surrounding skin, promoting strength and vitality.
  4. Cuticle Serum: Use the Cuticle Serum to target and rejuvenate your cuticles. Apply a thin layer along the base of each nail and gently massage it in. This helps to soften and hydrate the cuticles, promoting healthy nail growth.
