What the hair from your head? Depends. If you are talking about body hair, it just looks like that, but it's not true
Hair will not grow back stronger, but will be stronger if you trim the split ends off about every six to eight weeks. This keeps the ends from splitting up the hair shaft and weakening the hair reducing breakage. Your hair will also get longer faster due to the fact it is not breaking off on the ends.
It actually gets thicker. Try to stay away from heat. Try not to wash your hair to much. Your needs the natural oils. Apply leave in conditioner to damp hair.Sally's has good products. Good Luck!
