Dr Lewinn's Renunail Nail Strengthener 30ml

After dozens of products, this on e works. My nails were peeling so badly there was nothing left to file. In 2 weeks they had grown and have continued to improve. I cannot praise this highly enough.

I had used Dr. Lewinns Renunail strengthener before with success. The price I paid for a new bottle was rather expensive, and the varnish thickened in the bottle relatively quickly so I ended up having to throw it.

Don't like formaldehyde formulas and it did not state on site that this was. Makes my nails thin and "bendy" no strength at all. Plus it took a month to get here. Not recommended

I do have original bottle, this one does not have all the markings of Dr. Lewinn's nail strenghtener and again has wrong color

Excellent! This has strengthened my nails and saved me trips to the nail salon.I highly recommend this product. It does take a long time for it to arrive, however.

Excellent product my nails gave improved enormously as a result

fast shipping, have used this product for years & love it.

It is the best product out there! Too bad I can’t find it in the USA.

Strongly recommend, nails recovered in few weeks after 4 years having them filled by gel,

This is brilliant and really strengthens your nails and helps them to grow. Be sure to have a break and do as the instruction say ortherwise your nails will actually weaken.
