Claim against a beauty salon for negligence and damage

My wife recently had her nails done in Abu Dhabi.

During the so-called soaking off of the old nails which included using acetone & aluminium foil, after a time my wife noted her fingers were becoming sore.

After removing the foils, her fingertips were showing extensive burns. In 20 odd years, this has never happened. Can we claim for this type of negligence?

I have emailed the salon concerned, twice & messaged the owner, but have had no reply.

Please advise.

Thanks
