Mavala Scientifique Original Nail Hardener


Item Ships in 10-14 Business Days


Mavala Scientifique is a great solution for soft, flaking nails. Most nail hardeners are topical nail hardeners, meaning that they sit on the surface of the nail. Mavala Scientifique is a unique, patented nail hardener that is formulated to actually penetrate and bond the three layers of the nail together, forming a harder nail tip. It is perfect for soft, broken, ridged, peeling, splitting, or bendable nails. It's neither a base nor a nail polish. You use it specifically to harden and strengthen your nail tips. You can also purchase Scientifique Nail Hardener in a new handy Mavala Scientifique Pen Applicator version.

How to Use: To start, remove polish or any oily film and clean your nails thoroughly. Apply on to the free edge of your nails. Leave on for one minute to set. Apply twice a week at the most until your nails have become healthy and strong. Then two to three times per month if necessary. (Works well with Mavala Nailactan).

Precaution: Never apply under nail, on cuticles, or skin to avoid hardening of the epidermis. If any product runs on to the skin, wipe it off with damp cotton pad. Do not use more often than advised; otherwise your nails may become too hard, leading to breakage.

This really works
By Nancy from Houston, Texas from on 3/31/2014
I have been using this product for years & - am very happy with the results. I have thin, peeling nails. This product makes my nails harder & - keeps them from peeling. Normally , I wear nail polish continuously to protect my nails but even if I don 't, my nails are hard at the tips & - don 't peel. I definitely recommend using this product if you have nails like mine.

Good stuff
By Mak from Overland Park, KS from on 3/1/2014
My natural nails are thin and ridged. I buff them to get most of the ridges out and use mavala nail strengthener religiously. It's the only way I have any nails at all! I have also used mavala ridge filler, another great product, but I am rather low maintenance with regard to my nails at this point in my life, the less the better.

Great Product
By Karen Coleman from Rochester NY from on 11/1/2013
I saw improvement to my thin nails with the first application. I don't bother with the apparatus included, just be careful not to get this on your skin ( actually, some did touch my cuticle & - they didn't fall off!).

The only product that works.
By Anne from NY, NY from on 10/19/2013
I have been using this produce for decades. It works well without any ill effects. For most of my early life I had soft, cracking and peeling fingernails. Mavala Nail Hardener make my nails almost normal and I can enjoy shaping and polishing. Thank for making it available.

LONG time user
By Cyndilu from Riverside CA from on 4/7/2013
My mother and I started using this product in the mid-70's. Yep, 40 years ago. I highly recommend it to anyone who has soft, peeling nails. I will not use anything else. I also use the 002 Base Coat, and the Top Coat and my manicure lasts through 2 weeks of typing, dishwashing, and general household chores and still looks fresh. The only reason I change it at 2 weeks is to change the color. I know it's pricey, but a bottle will last for YEARS.

Sadly not working.
By Cynthia from Kadoka, SD from on 9/5/2012
I purchased 3 nail products hoping to get my nails shaped up, but Mavala just is not working for me. I've been using it for at least three months now and no improvement. I have moved on to trying other things.

Love this stuff
By Madeline from Elmer, LA from on 1/19/2012
I always had long,strong nails when I was younger but they would eventually break off. Soooo, I started having acrylic nails put on and almost ruined my nailbed. I was trying to take vitamins and let the nailbed grow out and searching for something on the web to help my weak nails. This stuff is awesome. My nails have gotten much stronger...no more peeling and chipping. If I forget to use it for a week or two I will start to have problems but with the first application again I see improvement. Just yesterday I was using a drill (yes I am a woman) and got my finger nail in a jam and it only took a tiny chip out of the nail...hurt like heck so I figured the nail was torn off but no. I love this product...please never go out of business.

Finally happy!
By Donti from Kansas City from on 1/19/2012
After (finally) giving up on acrylic nails - expensive, time consuming and not always healthy - I've struggled getting my nails to have any length at all. I tried creams, oils, everything. I ordered this with the attitude that it couldn't hurt. It is great! I've used for three weeks now and am starting to get some length in my nails. Definitely a keeper.

By Tabbitha from tacoma, WA from on 11/21/2011
I have almost run out of this stuff and was frantically searching on the internet on where to buy it from and came across this website..when i placed my order and became an active member it showed me that the original bottle I got 3 years ago was from here!! From this website! I was so happy to find it again and to realize this is where i purchased it originally in 2008! This is the best product ever! I've shown other co-workers how well this works instantly and they're amazed! They love it too!

Great Product. I like that it quickly penetrates, so you don't have to worry about drying time. My nails feel stronger.

Wonderful product for chronic nail biters. I have just purchased this for my daughter as she was very impressed with my nail growth.

I've used this product for years. DO NOT get this liquid on your skin. Apply VERY sparingly. Brush all the liquid off the brush and apply to nail from the center and then to each side. Works like nothing else in the world!

Good description
By Cynthia from Madison Wi from on 9/24/2011
I started using a similar formula that has been recently discontinued more than 40 years ago, and am thrilled to find this product! It really works and is well worth the cost. It is the formaldehyde, that is the ingredient you need for hard as steel nails & it is the main ingredient, so hard to find nowadays. Only on the tips, do not coat the entire nail. It dries very quickly and does not have a lingering odor. While you can put it over polish, I'll dab it on the back of the nail if I have polish on that I don't want to remove. It is a small bottle but a little goes a long way & it will take years before you use it all but it will remain usable in all that time as well. I received it within a week of ordering & it was well packaged.

Very Best Nail Hardner I have ever used!!
By Rita from Hartville, OH from on 9/24/2011
I have used this many years ago and then I could no longer buy it because the store didn't carry it anymore. What a disappointment for me, since nothing else ever worked that I tried!
I was so glad to discover this online store carried it! I just ordered a bottle of this and I am so excited to get back to using the BEST Mavala nail hardener there is!

Time will tell.
By Karen Collier from Pennsylvania from on 9/13/2011
I just started using this product, so it is too soon to tell if it is going to work or not. I can say that it does as it says, and dries the skin around the nail out pretty bad. I need to put vaseline around the skin of my fingernails before applying the Mavala. I do not have long nails so the little nail protecter that comes with the product to protect the skin around the nails does not work unless you have a good amount of free edge.
I am anxious to see if this will help my nails from splitting and breaking.

Best ofn the market
By Ruth from New York. from on 8/12/2011
I have very soft, brittle, peeling nails and have tried every product out there, with little success. I find that Mavala Original Nail Hardener is the only one that really works. It doesn't deliver miracle overnight results, but it definitely helps!

Don't hesitate, get this
By K from CT from on 6/23/2011
I have used this for less than a month but already see strength in my nails. It does not take much. The bottle looks tiny, but if applied properly, you don't need much. My nails are stronger and flexible, the peeling has stopped. Great Stuff!

By Anonymous from on 2/6/2011
I gave it 2 stars, I started using it the same day I received it and I can't tell any difference. My nails still peel and chip. I was so excited to get it, but it's no good for me.

Review for Mavala Scientifique (Original) Nail Hardener
By Anonymous from on 10/21/2010
I discovered this product 20 years ago when I received a nail kit as a promo gift from a now-defunct department store. I used it very frugally to make it last because I couldn't find it anywhere. I finally ran out and looked to the internet. I was delighted to find it at WhatSheBuys, and now I can use it with abandon, knowing I can get more. It is an amazing product and really works. I was also favorably impressed with WhatSheBuys, and will use them again and again.
