Greying of hair on front-part.Looking awkward-Any solutions??????

Hi all,
I am 30 + years and from the past one year I am experiencing grey hair . That too the hair is turning grey mostly in the front part. I use henna for every fifteen days. But as my hair grows faster, the front part hair roots again grow grey. What to do? I am working and hence it is looking very awkward. My colleagues tell me to dye my hair.But I don't prefer.Even if I apply hair colour I think again I will face the same problem.Any solution friends??? Is there any henna which stays for at least ten days???? At present I am using Anoo's henna.:drowning:drowning

 

Thank you for your responses. How do we prepare henna oils ?
