True Black Hair

I have very kinky hair transitioning from a relaxer (12 weeks post). I'm a type 4 hair which generally feels coarse to the touch.  When not in my lace front wig or weave I simply spray with s curl after I have washed and deep condition and towel dried.   I also use essential oil be it olive oil, alma oil, jasmine oil....so many to choose from. I learned to do this on a forum and it is a life saver.  S curl does soften the hair and makes combing with a wide tooth comb from ends to roots more manageable.  I cannot suggest anything that will naturally straighten the hair, so if you want it to retain its health without the heat I suggest weave or wigs which to me are protective styles. So my regime is wash, condition once a week, spray with s curl and infusium leave in conditioner, seal with essential oil, then I cornrow or plait in two.....wear my wig for a week and then start again.  I hope this helps as an alternative idea.
