I have very weak nails and the years of semi-permanent polish have destroyed them. After each removal, they need at least 2 months to recover. The oil is the best I have tried, but it does not have any substantial long-term results. My nails show some improvement, but nothing drastic.

Honestly, I didn't expect it, I had tried almost all types of nail polish, but my nails continued to be weak, brittle, peeling, etc.
It is the only product that worked, now I have nails, they don't break, they don't peel and the vertical lines have noticeably reduced. If they disappear completely over time, I will update.
I've been using it for about a month, once a day, before bed and before applying hand cream.
It deserves ten stars!

Excellent product. My nails were a mess after I removed the gel. Like soft flakes, rough, with vertical splits. I was embarrassed to show them. After a month of daily use before bed, they transformed into healthy, smooth, hard nails. Very satisfied!!!

Amazing product! It does everything it promises! I had a toenail for years that I was trying to fix after an injury and almost destruction since it wouldn't stick with anything and didn't grow a new one except for a little while and then it would come off again. With good care with a file, I managed to clean it and grow it very slowly, but when I started using this product, the nail began to grow rapidly!

After trying various nail strengtheners, this one made a difference. From the first applications, my nails recovered, stopped peeling, and became strong. I highly recommend it!!! It saved me

Very good, it immediately moisturizes the nails and in combination with a keratin product helps to rebuild and grow a thin, fragile, and damaged nail from semi-permanent and acrylic.

If there was a 6th star, it would deserve it. Already from the first 2 days of application, my nails started to regenerate. After removing semi-permanent manicure with a file, my nails had become fragile, weak, they immediately peeled and broke. 6 months passed without the slightest improvement. I bought this oil and used it daily, one drop on each nail. Not even a month later, my nails are long, strong, as if I had applied a hardener.

I used it for about a month and what I understood from using it was that it felt like a dullness on the skin, but that wasn't the problem. The problem was that instead of softening the skin, it started to become harder and peel off constantly every day, and new skin would appear. From not having a problem with the skin, I acquired the little star only because it did something to the nails, they became somewhat more resistant.

Very good & affordable product!
It does exactly what it promises.
If you have damaged or weakened nails, or even if the nail plate has been significantly damaged, it will strengthen and greatly assist in nail growth.
Of course, all of the above with systematic use, and as a bonus, the herbal scent it gives off...

Only Gehwol products saved me from toenail fungus. I have tried them all (cream, liquid, and the 'pen'/stick). Especially the last one, I highly recommend it due to its user-friendly shape.

Nail oil that softens and promotes healthy nail growth. It absorbs quickly and promises to strengthen brittle nails. It has a herbal-chamomile scent and has visible results, provided that it is used daily.

It is an oil that even from the first day you see differences in your nails. I had very fragile nails but this product whitens and strengthens the nails. They appear healthier!
