Answer: Brittle nails can be attributed to ageing and frequent exposure to water or various cleaning products.
To avoid brittle nails, wear rubber gloves when you wash up and/or use harsh chemicals. You can also try incorporating green vegetables and oily fish into your diet as these ingredients are high in nutrients that will strengthen nails and encourage growth. Taking vitamin B supplements will also help to strengthen the nails.
To treat brittle nails massage a nail and cuticle oil into your nails at least once a day and start using a good strengthening treatment.
