The tip of your nail is the most fragile, most unprotected part and breaks easily. That’s why it’s the part of your nail we need to strengthen.

Mavala Scientifique is a great solution for soft, flaking nails and I'll tell you why.

Hardens As It Penetrates Your Nail Tips…

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’s so powerful and unique that you’ll feel the results in seconds!

Mavala® Scientifique 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.

  • Helps To Bond The Layers Of The Nail Together
  • Hardens The Nailplate
  • Puts An End To Splitting Nails

You can also purchase Scientifique Nail Hardener in a new handy Mavala Scientifique Pen Applicator version. It might make application a little easier for you.

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.

Quantity: One .16 fl. oz./5 ml bottle. Made in Switzerland by Mavala®.

Great Product
By Karen Coleman from Rochester NY on November 2, 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!).
It's not a polish; actually penetrates the nail
It's fast, easy, and works

I would recommend this item to a friend.

The only product that works.
By Anne from NY, NY on October 20, 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.
Easy to apply, and works for a decent time period.
h\Hard to find in stores.

LONG time user
By Cyndilu from Riverside CA on April 8, 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 on September 6, 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.

Excellent product
By Lin from Bellingham, WA on March 11, 2012
This product is easy to use and really lives up to its promise. My nails have never been so strong. No more peeling. No breaking. Love Mavala!!

Love this stuff
By Madeline from Elmer, LA on January 20, 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.
Does just what you said it would do. I have long , strong nails again that are my own.

I would recommend this item to a friend.

Finally happy!
By Donti from Kansas City on January 20, 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.
Easy to use, Quick results

I love this stuff!! It's awesome! 1 bottle lasted me a LONG time!
By Tabbitha from tacoma, WA on November 22, 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 soo 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!
How hard and strong it makes my nails! It is well worth the price, trust me!!! I'm a penny pincher but this is totally worth it!
Only that it's a little hard to find, but now that i've found it again I'm ecstatic!

I would recommend this item to a friend.

Great Product!
By Zulema from Hammond, Indiana on November 9, 2011
Great Product. I like that it quickly penetrates, so you don't have to worry about drying time. My nails feel stronger.

This has worked so well for me, a longtime nail biter who now has fingernails.
By Maureen Lyons from Portsmouth, Rhode Island on October 25, 2011
Wonderful product for chronic nail biters. I have just purchased this for my daughter as she was very impressed with my nail growth.
Easy application.

I would recommend this item to a friend.

By Strong Nails from Florida on October 20, 2011
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!

I would recommend this item to a friend.

Very Best Nail Hardner I have ever used!!
By Rita from Hartville, OH on September 25, 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 hardner there is!

It goes a long way and it really does harden soft, split and fragile nails!

I would recommend this item to a friend.

good description
By cynthia from Madison Wi on September 25, 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.
formadehyde is the neccessary ingredient needed & it is the 2nd item on the list.
I like the plastic collar inside the neck of the bottle, less waste with it.
following the directions it will take years to use it up, but it will last that long as well.
Honestly thr price. I know the formula, I know it works, I'm willing to pay it, but for the skeptic who has been taken by other products it's a hard price to pay up front. IF I had not ever tried the formula I probably would not have purchased this without some serious incentive like get another product for half off. I love free shipping but sometimes that is not enough to try a new product.

Time will tell
By Karen Collier from Pennsylvania on September 14, 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.

how it dries out the skin around the nails

Merchant Response:
A little bit of this product goes a long way. To prevent product from seeping onto your skin, swipe the applicator brush against the rim of the bottle before applying. This will prevent an over saturated brush from leaking product onto your skin. For additional control when applying Mavala also offers the Mavala Scientifique in a pen applicateur.

Been using this product for a while and i now love my nails. My nails use to break or crack a lot now they are beautiful.

Best ofn the market
By Ruth from New York on August 13, 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!
Ease of application
Absorbed by the nail

Don't hesitate, get this
By K from CT on June 24, 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 on February 7, 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.

By Anonymous on October 22, 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.
