I'm a nail expert and women have no idea how much damage they're causing with this one seriously bad habit - and thousands are doing it

Experts are warning women to stop picking their nail polish off immediately if they want to avoid irreparable damage to their nail beds.

Speaking to FEMAIL, Jenny Wiles, a global trainer from Mavala Switzerland, said picking at old nail polish is a 'complete no-no', especially for those who get synthetic treatments.

'Peeling away polish and/or synthetic treatments like gels or shellac causes micro-trauma for the nail and ripping it off literally takes layers off your natural nails,' she warned.

'This in turn thins the nail and leads to further damage and potential infection.'

Doctors are also warning against the simple act, with Dr Dana Stern, a board certified dermatologist, saying it has a 'knock-on effect on the nail bed and root, which sees critical blood and nutrients flow reduced'.

'Start by giving your nails daily attention and care – you will see an immediate improvement' 

'I have experienced clients who think they are peeling just polish, but in fact are peeling chunks of their natural nail, leaving the nail bed exposed,' she told The Huffington Post. 

For those who have already caused significant damage by picking their nail polish off, hope is not lost. There is plenty that can still be done to aid repair and improve growth.

'Cuticle care is the holy grail of nail care,' Jenny said. 'Apply a topical treatment or oil twice a day to soften them.' 

 Nail hardeners and a proper diet can help damaged and brittle nails. Silicium is like ‘cell cement’ and helps nails to grow faster and be more resistant. It can be found in onions 

She also advises a 'penetrating nail hardener' such as the Mavala's Scientifique K+ $32.95, which is made without formaldehyde. 

As a reminder, Jenny said that while 'synthetic nails can be addictive, its important to break the cycle for a sustained period to allow your natural nail health to be restored.'

She also stresses the importance of diet when it comes to nail health.

'A key mineral is silicium, which is like "cell cement" and helps nails to grow faster and be more resistant,' she said.

'It's found in vegetables, in particular garlic and onions'.

'Also try to minimise exposure to harsh chemicals and water and wear gloves when you do'. 

Jenny recommends in-salon treatments such as the naked manicure from Sydney nail guru Jocelyn Petroni in Woollahra.

The treatment $90 treatment is 45 minutes long and includes replenishing hand and arm massage using European, Shiatsu and Reiki techniques.

The naked manicure 'focuses on the health of the nail with no polish, just glowing natural nails'.
