I have been using MT for 10 days now and I have seen a difference in my hair growth already! My hairline has been damaged from too tight braids, buns, ponytails, wearing a cotton scarf. Pretty much every hair sin. Sometimes I would look in the mirror and feel like crying because I will never forget when a cousin of mine kindly remarked that I needed to stop with the tight braids if I wanted my hairline to grow back. This was after I had convinced myself that no one else could notice the lack of hair there.
Anyway fast forward to now, 10 full days of using MT every day on my hair line. Although I'm still not ready to wear my hair all back, there are little hairs sprouting there! Before that area was so bare that I could see the little holes where hair should have been growing out of. Not to be overly religious but every night I thank God for guiding me to MT and allowing it to work.
For the other parts of my hair I apply MT once a week and then leave it in until my next wash which is usually a week max (I have a very oily scalp). I've seen growth in the past 10 days in these other sections as well.
