I am Dr. Arun and will be helping you today.
I am sorry that your question was unanswered for long.
This may occur due to a variety of conditions.These include deficiency of nutrients like Iron deficiency, biotin and niacin, vitamin deficiencies like Vitamin C ,B5, B12 and folic acid. Repeated wetting and drying of the nails may also cause the problem.
Exposure to certain detergents and chemicals may also be responsible, repeated minor trauma to the nails will also cause this. Use of nail polish remover should be limited to not more than twice a month. Lack of adequate proteins in the diet can also be causative. Consuming a diet which is rich and balanced will help prevent such nail issues.
Regular use of thick creams like Neostrata (contains alpha hydroxyacids/Elon (contains Lanolin) after wetting the nails, especially at bedtime, to hydrate the nails may help. Lastly thyroid disorder should be ruled out by the blood work, if not yet done.
An opinion from a Dermatologist may help if symptoms persist. Taking colloidal mineral and multivitamin supplements may also help.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
Thanks for using Just Answer.
