My stylist recommended waiting a while in between relaxers. I guess it all depends on the stylist and what they know about your hair. I normally don't experience any of those things and I have stretched my relaxer to as long as 4 months.
I've only stretched my relaxer out to 4 months one time and that killed me. My new growth was so thick and I think the only reason I was able to stretch it out that long was because I got my hair braided just to keep from perming it.
