I bleach the hell out of my hair and heat style it like crazy and I can suggest a few amazing product. Not guaranteeing they'll work for you since not everyone reacts to products the same way, but definitely worth a try!
- Joico K-PAK RECONSTRUCT deep-penetrating reconstructor
- Redken Extreme Anti-Snap leave-in treatment
- Pantene Pro-v Restoratives Breakage defense strenthening spray
- Aussie original 3-minute miracle - LOVE IT!
- Paul Mitchell super skinny serum - great for smoothing your hair and making it look real healthy after styling it
- Bead Head Tigi after-party smoothing cream - same as the skinny serum
- Abba Creme-Moist Shampoo
Also, look at getting a good heat protecting spray. I need a new one so I can't think of any good ones of the top of my head, but check out
http://www.makeupalley.com they have millions of reviews on any beauty product imaginable. I don't buy any product without looking on this site first.
But like mentioned above deep condition at least once a week. I personally do it maybe 2 or 3 times a week and leave the deep conditioner in for a minimum of 20 minutes. Lol just wrap it up in plastic wrap heat it up with a blow dryer wrap a towel around my head and go about whatever I'm doing in my house lol.
Oil olive is also an amazing deep conditioner for your hair but make sure you have a good clarifying shampoo to wash it out or you could be left with really greasy hair. You may even have to shampoo it with a clarifying shampoo twice, but it really is worth it.
Another thing is if my hair is tangled I don't even attempt to brush it and break off pieces of my hair I just hop in the shower use a conditioner first to untangle it then use shampoo and then conditioner again.
And, obvious one try to avoid heat styling...hard one though I know lol.
