Yeah man kief is really good, ive never gotten a headache from it. Depending on the strain you smoke though, the THC might be more in the plant material rather than the actual trichomes. There are plenty of strains out there that aren't super frosty like white widow but still pack a super high.
The only thing I can recommend is maybe adding a little green in with it to help out. As I said before some strains create resin with lower THC percentages yet the actual bud is potent as hell.
Some people look for high quality, less resinous strains because trichomes are harsher to smoke.
