Nail Hardener & Nail Strengthener for Thin Nails and Growth - Nail Growth Treatment, Protection & Nail Repair for Damaged Nails - Formaldehyde-Free Base Coat Nail Polish, 0.47 Fl oz

I’ve only been using it for 18 days (2.5 weeks) and you can already see the growth. I really didn’t think it would work for me but saw a lot of positive reviews, so figured I would just give it a try… no regrets!I don’t bite my nails, they just crack or peel and are extremely weak. I don’t even do acrylic anymore and they’re still soft and weak.I’m really satisfied with the results and excited to see what they look like after a full month.This was only using the white one .. I have yet to try the one with ajo and limon..My cuticles on the other hand… well.. lol

This polish is fabulous. The bonus to it fulfilling its primary function of strengthening and whitening the nails is that it lasts for a long time, too. Also, no pungent smell so characteristic of nail polishes. I've been looking for something like this for years and finally found it. Very happy with my purchase and would buy again.

Lo uso abajo del esmalte. Oh aveces lo uso así naturalmente y queda perfecto 👌Soy de uñas muy delgadas y quebradizas y este endurecedor es muy bueno..

Siempre lo uso me encanto saber que lo encuentro aquí y me encanta

The product smells very strong but it works.

Super bueno

Excellent

Probably was a good idea if Amazon have a policy to the companies ( sellers in general)To comply with the requirements to specify the ingredients information.I know some sellers are top notch on advertising their own products in a honest manner.For example this seller don’t do that .Their product have a component (formaldehyde 37%) may make nails brittle and more likely to break or peel. Nail products that contain formaldehyde may also cause skin irritation, as well as allergic reactions to this ingredient.And can’t returned. Waste of time and money
