I am fine/thin haired, normal porosity normal elasticity. I have tried a few PT's and they don't seem to have much of an effect on my hair. If anything, my curl loosens a tad. Although my hair gets amazing shine. I have tried gelatin, Ion Effective Care and GVP Joico K pack, always following with a DT. My question is, what are typical results if using a PT? Does it cause hair to curl more or just make hair healthier? My hair does not dry out with PT's but does frizz when I use Epsom salt spray or NPF as a spray.
Having said all that, last weekend I tried a PT of Ion (no DT that time), nothing much happened. Loose curls though, so I did a DT of GVP CB the next day, and got amazing curls! I didn't know if the PT the day before caused the results or just the DT.
