If you look at the box for #4, smaller on the front, it says Xtra. **Q: In tek guide says after applying layer of Tek apply polish and then apply Tek within to seven days how many layers will be then?** A: I am using the ridge filler. I apply NailTek, then 2 layers of color (I use sheer, deep color my require just one coat) and finish with a quick drying top coat weekly. I do not add more layers. **Q: How do i get this out of clothing?** A: It is like a nail polish. You can use either an acetone or non-acetone nail polish remover. I use the non-acetone remover to remove it from my nails. You will need to test it on a hidden part of the fabric as it is very likely that it will affect dyes in the cloth or even attack the fabric if it is a synthetic. **Q: Is it necessary to use both the nail tek protection plus iii & nail tek (4) strengthner ?** A: I'm not sure if you need both. I tried the (4) strengthener and it really didn't help my nails. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***O on February 18, 2026* ### ⭐⭐⭐⭐⭐ Review *by C***K on December 13, 2025* ### ⭐⭐⭐⭐⭐ Review *by B***A on February 11, 2013* ## Frequently Bought Together - Nail Tek Xtra 4, Nail Strengthener for Weak and Damaged Nails, 0.5 oz, 1-Pack - Nail Tek Nail Nutritionist, Keratin Enriched Nail Treatment Oil for Weak and Damaged Nails, 0.5 oz, 1-Pack - Onyx Professional Hard as Hoof Nail Strengthening Cream with Coconut Scent, Nail Growth & Conditioning Cuticle Cream Stops Splits, Chips, Cracks & Strengthens Nails, 1 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/3078931-nail-tek-strengthener-xtra-4-strengthener-and-base-coat-0](https://www.desertcart.vu/products/3078931-nail-tek-strengthener-xtra-4-strengthener-and-base-coat-0) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
