Thanks for posting your query at DoctorSpring.com
I can understand your concern.
I had a look at the nails but I couldn't note the fissures. You do have vertical lines but that's considered normal. However, I would request you to send me a picture of your nails before you feel you got the fissures and also the chance in colour, so I can get a better idea of the change in the nails.
Feel free to discuss further,

Ok, I am sending pictures and I cannot upload them. cant you dend me your email. Thanks.
Thanks for the images.
You don't seem to be having any other pathology in the nails except brittleness of the nails. The vertical lines can occur even in normal individuals and do not always suggest anything specific.
The color change that you mention didn't appear to be significant enough to take any treatment or suggest a major pathology.
I would recommend that you take supplements of the vitamin called biotin daily for three months.
That should help reduce the brittleness of the nails.
Please let me know if you have any queries.
