Thanks for your query,
I think your doctor had given you right advise.You go with clop lotion.It has usually no side effects but when applied first time it should be checked with allergic shin reaction.
The most important thing is vitamin tablets.Don't forget to take it.
I also advised to take food rich in vitamins
like spinach leafy vegetables.
In addition to it take vitamin E
for 2 months.Apply some plain coconut oil in to hair & massage
it on scalp
will help you further.It takes atleast 6 months to regain your hair growth.Thanks
