Hey so I had trouble with my hair growing I dyed it a lot and changed the style loads and really wanted it to go, but because it was so damaged it really wasn't making much progress. I decided to get my hair chopped into a longish crop haircut. Quite boyish but also suits me. I was just wondering how long do you reckon it would take to grow to like a nice long bob length and then so on... I know it's a lengthy process... but is there any ways to fasten the process? I did this to see if it will grow back healthier :) thanks

Hair grows about 6 inches per year (15 cm / year).

There are lots of claims for things that will make your hair grow -- vitamins, tonics, etc. So far, I haven't seen anything that I believe.
