Sally Hansen Diamond Nail Hardener Review

Sally Hansen Hardener

After so many hours spent on nails done with acrylic and gel, all the polish with buffers or drills, my nails need a break from time to time. We all know that applying acrylic on your nails in time will make them bendy and thin.

I cannot say that I have strong nails without applying any treatment from time to time. So, when I decide to give them a break, among the others, I use Sally Hansen Instant Nail Hardener. This nail strengthener is also one of my many favorite nail products. The protective coating seals the nails allowing them to increase the texture

Features:

Sally Hansen Diamond Strength Instant Nail Hardener will help your nails grow beautifully and harden their structure. This product will help you give a refresh to your nails. You need to use it in layers, one layer per day.

You donโ€™t need to remove the previous layer each day, just reapply and after 4-5 days remove all the layers and repeat the process. In time youโ€™ll see the benefits of this product and its excellence. Itโ€™s a remedy for soft, thin, cracked, or peeling nails.

๐Ÿ‘ Pros:

  • Helps the nails to grow naturally
  • Offers a strong structure
  • Looks nice on nails and gives a cute shine.

๐Ÿ‘Ž Cons:

  • Itโ€™s not matte, but shiny, I do not see it as a bad thing as I like shiny things, but a matte version could be easily accepted and used by men too.

Sally Hansen Nail Hardener Q&A

Can be used under acrylic nails?

No. Acrylic nails need a firm surface to adhere to. I would not recommend under acrylic but it can be used as a top-coat.

Does this need to be removed?

Yes. If you use it as a treatment to hardener your nails I would recommend you to apply it in layers, one per day. After 4-5 days you should remove with acetone and repeat the process.

Final thoughts

For you to see the results when using Sally Hansen Diamond Instant Nail Hardener as a treatment be patient with your natural nails to grow. This product will offer a strong structure and allow them to harden, grow, and recover. Itโ€™s a great product for thin, bendy, peeling nails and amazing for recovery after using a lot of acrylics.

With a ridge filler, a strengthener, and cuticle oil, the peeling nails will become a memory of the distant past. The unique formula of the products will seal the layers of the nail and will moisturize and nourish the cuticles.

NailTek Features

Containing a ridge filler, a strengthener, and cuticle oil, this package has it all. The ridge filler will permeate the crinkles and fill the nail, the strengthener with its unique protein formulation will harden the nail, while the cuticle oil will provide the finishing touch, nourishing the skin.

๐Ÿ‘ Pros:

  • Stops the peeling of the nail.
  • It is a great recovery product for the nails that were covered by acrylic/gel.
  • The ridges are filled, leaving a nice and smooth finish behind.

๐Ÿ‘Ž Cons:

  • While the polish covers the discoloration, it does not necessarily get rid of it.

NailTek Nail Recovery Kit Q&A

Yes, you do not need to apply the products over polish.

Do the products dry quickly?

Yes, they dry pretty fast.

Can you use the products on toenails too?

Yes, they have a great effect on toenails too.

Final words on NailTek

Iโ€™m giving this set a 10/10 credit for my nails remaining strong and beautiful. While they grow pretty fast, they have a tough time staying like that as theyโ€™re pretty thin. The filler is smooth and has a beautiful matte finish.

Topping with the clear strengthener will help prevent new damage and the cuticle oil will provide the finishing touch. All in all, receiving the 3 products in the kit is a good deal.
