With using MN that is. I finished my last bit yesterday, and I've been using it consistently since December 2011. Since my first mix, I went to a more potent option with 3 oz of castor oil + the same amount of MN. I have been applying it to my scalp daily.
I am scheduled to relax my hair in two weeks, so I wanted to be sure to stop using MN at this point. I want to give my scalp a chance to rest because I still don't know what the implications of mixing MN + relaxer are, and I have no intentions of finding out.
I am curious to see if I have experienced accelerated growth as a result of using MN. If I decide to use it again, I don't plan to do so until the end of this year. I don't really want to become dependent on a growth aid to reach my length goals, so I told myself that I would only use it between relaxers, once per year (the same way I did it this time).
I'm planning to do a length check after my next relaxer, so at that point I'll assess whether or not I experienced better growth.
