Your nails can become brittle and weakened for a number of reasons, ranging from iron deficiencies to using harsh products here. I would recommend looking into our Utricalcin Stinging Nettle Complex. This contains a combination of silicea, calcium, sodium salts and the stinging nettle herb which can actually help to strengthen your nails (and possibly your hair too!).
You could also try reading my blog, ’10 ways to keep your nails in tip top condition’ as this takes a deeper dive into how you can look after and maintain your nails, discussing diet and lifestyle habits as well as products that might be able to help.
I hope you found this information helpful. Please let me know if you have any other questions.
