I'm sorry if I ame off defensive, I'm just use to newly natural, or girls who are just learning to care for curly hair properly giving me advice like I am new to curly/natural hair when I've had it all my life. (this is my first, and only chemical treatment ever) ^^
Also I know the chemical is not the issue I had my retouch around last Feb., and seeing as dryness is not a usual issue of mine. Usually my hair is in pretty perfect condition. I just think my DC is not penetrating very well, possibly due to the overuse of protein, or because the pH is not suitable for my hair.
I'm gonna try a lower pH dc, and lay off the protein for a few a few weeks, and slowly add it in before my hair gets overly mushy from moisture >.<
