Lots of fresh air and sunshine also try eating lots of healthy foods. One summer I noticed my hair and finger nails were growing like weeds, also my skin was healthy. Normally I have about 1 inch of growth every month. Keep stress down and exercise. I found walking for about 1 hour was so good for every little problem. A trip to the hair dresser every 6 to 8 weeks for a trim, only get the ends taken off 1 cm. I shampoo & condition every 2nd day. I wet my hair every day. I color, highlight, use a curling iron and a hairblower I use a pick, comb and a brush once in a while for smoothing and shine. Hope this helps! Oh yes one last thing, patience.
Bye for now!
