I have good nails growth but the problem is with the index finger of my hands. It doesn't grow like other nails. How can I treat it. Thanks in advance.

You need to take calcium tablets and eat calcium-rich foods for good hair growth take biotin. Biotin is an important type of b vitamin that allows the body to turn food into energy. Use nail hardeners (sparingly) nail softness makes nails more prone to breaking, which increases the need for nail regrowth. Avoid glue-on nails and toxic polishes. Practice good grooming. Reflexology also believes that rubbing nails can help in treating hair loss effectively. The nerve ending lying just under the fingernails are directly connected to the hair follicles present in the scalp. By rubbing your fingernails you can stimulate the blood circulation in your scalp.
