Review on 💅 Nail Tek Nail Nutritionist: Strengthen & Repair Weak Nails with Keratin Enriched Treatment Oil - 0.5 oz, 1-Pack by Abunsefer Chongbang

I know quite a few people who like it. It was recommended to me by a woman who never leaves the house without applying it to her nails. But for me it was a disappointment. Applied unevenly (looks like there are crystals in it) and left my nails very dry and also yellowed. Not sure if it's a personal chemical interaction or what's causing these mixed results, but it might be worth a try if you have weak nails. Don't get your hopes up too high though because I did and was so disappointed! It wasn't the holy grail for nails, at least for me.
